PSB 9000 2.5 kW Series 1.9.9 Analog interface This 15 pole Sub-D socket on the back side of the device is provided for remote control of the device via analog or digital signals. If remote control is in operation this analog interface can only be used alternately to the digital interface. However, monitoring is always available.
PSB 9000 2.5 kW Series 1.9.13 GPIB port (optional) The optional GPIB connector, which is available with option 3W, will replace the module slot of standard version devices. The device then offers a three-way interface with GPIB, USB and analog. The connection to a PC or other GPIB port is done with standard GPIB cables from stock, which can have straight or 90° connectors. When using cable with 90° connectors, the USB port will be inaccessible. EA Elektro-Automatik GmbH Helmholtzstr.
PSB 9000 2.5 kW Series 2. Installation & commissioning 2.1 Transport and storage 2.1.1 Transport • The handles on the front side of the device are not for carrying! • Because of its weight, transport by hand should be avoided where possible. If unavoidable then only the housing should be held and not on the exterior parts (handles, DC terminal, rotary knobs).
PSB 9000 2.5 kW Series 2.3.2 Preparation Mains connection for a device with a 2.5 kW power rating is done via the included 5 pole socket on the back of the device. Wiring of the included plug requires a 3 wire lead of suitable cross section and length. For recommendations about cable cross section see „2.3.4. Connection to AC supply“. The device mustn’t be operated on a standard wall socket. It requires a rigid connection to a properly fused supply point. See section 2.3.4.
PSB 9000 2.5 kW Series 2.3.4 Connection to AC supply • Connection to an AC supply must only be carried out by qualified personnel and the device must always be run directly on a power grid (transformer are permitted) and not on generators or UPS equipment! • Cable cross section must be suitable for the maximum input current of the device! See tables below.
PSB 9000 2.5 kW Series 2.3.4.3 Strain relief and plug fixture There is a standard fixture mounted to the AC input connection block on the rear. It’s used to prevent the AC plug from loosening and disconnecting due to vibrations or similar. The fixture is also used as strain relief. Using the 4x M3 acorn nuts, it’s recommend to mount the fixture to the AC filter block every time the AC plug has been plugged again.
PSB 9000 2.5 kW Series 2.3.4.5 Protecting the electrical installation when using energy recovering devices A PSB 9000 device recovers energy and feeds it back into the local power grid. The generated current adds to the grid current (see schematic below) and this can lead to an overload of the existing installation. Considering any two outlets, no matter of what kind they are, there is usually no extra fusing installed. In case of a defect in the AC part (i.e.
PSB 9000 2.5 kW Series 2.3.5 Connection to DC loads or DC sources • In the case of a device with a high nominal current and hence a thick and heavy DC connection cable it’s necessary to take account of the weight of the cable and the strain imposed on the DC connection. Especially when mounted in a 19” cabinet or similar, where the cable could hang on the DC terminal, a strain reliever should be used.
PSB 9000 2.5 kW Series 2.3.5.2 Cable lead and plastic cover A plastic cover for contact protection is included for the DC terminal. It should always be installed. The cover for type 2 (see picture above) is fixed to the connector itself, for type 1 to the back of the device. Furthermore the cover for type 1 has break outs so that the supply cable can be laid in various directions.
PSB 9000 2.5 kW Series Figure 8 - Example for remote sensing wiring with load in source mode (sink mode will be wired identically) 2.3.9 Installation of an interface module The optionally obtainable interface modules can be retrofitted by the user and are exchangeable with each other. The settings for the currently installed module vary and need to be checked and, if necessary, corrected on initial installation and after module exchange.
PSB 9000 2.5 kW Series 2.3.10 Connecting the “Share” bus The “Share” bus connector on the back side is usually connected to the Share bus connectors of further units of series PSB 9000, in order to balance the current between multiple units in parallel operation, especially when using the integrated function generator of the master unit. For further information about parallel operation refer to section „3.12.1. Parallel operation in master-slave (MS)“.
PSB 9000 2.5 kW Series 3. Operation and application 3.1 Terms The device is a combination of a power supply and an electronic load.
PSB 9000 2.5 kW Series The same occurs with a positive load step, i.e. low load to high load. There the output collapses for a moment. The amplitude of the overshoot or collapse depends on the device model, the currently adjusted output voltage and the capacity on the DC terminal and can thus not be stated with a specific value. Depictions: Example for neg. load step: the DC output voltage will rise above the adjusted value for a short time. t = transient time to settle the output voltage. 3.3.
PSB 9000 2.5 kW Series 3.3.4 Internal resistance regulation (source mode) Internal resistance control (short: CR) of power supplies is the simulation of a virtual internal resistor which is in series to the load. According to Ohm’s law, this resistance causes a voltage drop, which will result in a difference between the adjusted output voltage and the actual output voltage.
PSB 9000 2.5 kW Series 3.3.6 Sink-source mode switching The switchover between sink and source mode happens automatically and only depends on the device’s voltage setting and actual value on the DC terminal or the remote sense connector, if in use. It means, that when connecting an external voltage source to the DC terminal, only the voltage set value determines the operation mode. When connecting a load which can’t generate a voltage, only source mode can be run.
PSB 9000 2.5 kW Series 3.4 Alarm conditions This section only gives an overview about device alarms. What to do in case your device indicates an alarm condition is described in section „3.7. Alarms and monitoring“. As a basic principle, all alarm conditions are signaled optically (text + message in the display) and acoustically (if activated), as well as status via digital interface. In addition, the alarms are reported as signals on the analog interface.
PSB 9000 2.5 kW Series 3.4.6 Safety OVP This extra feature is only built into the 60 V model of this series. Similar to the regular overvoltage protection (OVP, see 3.4.3), the Safety OVP is supposed to protect the application or people according to SELV. The alarm shall prevent the device from providing an output voltage higher than 60 V. However, the alarm could also be triggered by an external source providing an excess voltage to the DC input of the device.
PSB 9000 2.5 kW Series 3.5 Manual operation 3.5.1 Switching on the device The device should, as far as possible, always be switched on using the rotary switch on the front of the device. Alternatively this can take place using an external cutout (contactor, circuit breaker) of suitable current capacity. After switching on, the display will first show some device related information (model, firmware versions etc.) and then a language selection screen for 3 seconds.
PSB 9000 2.5 kW Series 3.5.3.1 Menu “General Settings” Setting Allow remote control Description Selection “NO” means that the device can’t be remotely controlled over either the digital or analog interfaces. If remote control isn’t allowed, the status will be shown as “local” in the status area on the main display. See also section 1.9.6.1 Analog interface range Selects the voltage range for the analog set values, actual values and reference voltage output. • 0...5 V = Range is 0...
PSB 9000 2.5 kW Series Setting DC terminal after remote Description Determines the condition of the DC terminal after leaving remote control either manually or by command: • OFF = DC terminal will be always off when switching from remote to manual • AUTO = DC terminal will keep the last condition Enable R mode Activates (“Yes”) or deactivates (“No”) the internal resistance control. If activated, the resistance set value can be adjusted on the main screen as additional value. For details refer to „3.3.4.

PSB 9000 2.5 kW Series RS232 IF Level 1 - Element Com Timeout Description The baud rate is selectable, other serial settings can’t be changed and are defined like this: 8 data bits, 1 stop bit, parity = none Baud rates: 2400, 4800, 9600, 19200, 38400, 57600, 115200 Description Timeout USB/RS232 (in milliseconds) Default value: 5, Range: 5...65535 Defines the max. time between two subsequent bytes or blocks of a transferred message.
PSB 9000 2.5 kW Series 3.5.4 Adjustment limits Adjustment limits are only effective on the related set values, no matter if using manual adjustment or remote control setting! Defaults are that all set values (U, I, P, R) are adjustable from 0 to 102%. The full range may be obstructive in some cases, especially for protection of applications against overvoltage. Therefore upper and lower limits for current (I) and voltage (U) can be set separately, which then limit the range of the adjustable set values.
PSB 9000 2.5 kW Series 3.5.6 Manual adjustment of set values The set values for voltage, current and power are the fundamental operating possibilities of a power supply and hence the two rotary knobs on the front of the device are always assigned to two of the values in manual operation. For each mode, sink and source, the device has separately adjustable set values for current, power and resistance which are labelled accordingly in the display.
PSB 9000 2.5 kW Series 3.5.7 Switching the DC terminal on or off The DC terminal of the device can be manually or remotely switched on and off. This can be restricted in manual operation by the control panel being locked. After switching it on, it either works as input (sink mode) or output (source mode). More information can be found in „3.3.6. Sink-source mode switching“.
PSB 9000 2.5 kW Series 3.5.8.
PSB 9000 2.5 kW Series 3.6 Remote control 3.6.1 General Remote control is possible via the built-in analog or USB port or via one of the optional interface modules (only with standard models) or via the GPIB port (only with option 3W installed). Important here is that only the analog or one digital interface can be in control. One of the digital ones is the master-slave bus.
PSB 9000 2.5 kW Series 3.6.3.2 General information about the interface modules With the standard models of series PSB 9000, one of the plug-in and retrofittable modules listed in 3.6.3.1 can be installed. It can take over remote control of the device alternatively to the built-in USB type B on the back side or analog interface. For installation see section „2.3.9. Installation of an interface module“ and separate documentation.
PSB 9000 2.5 kW Series 3.6.4.2 Resolution The analog interface is internally sampled and processed by a digital microcontroller. This causes a limited resolution of analog steps. The resolution is the same for set values (VSEL etc.) and actual values (VMON/CMON) and is 26214 when working with the 10 V range. In the 5 V range this resolution halves. Due to tolerances, the truly achievable resolution can be slightly lower. 3.6.4.
PSB 9000 2.5 kW Series * AI = Analog Input, AO = Analog Output, DI = Digital Input, DO = Digital Output, POT = Potential ** Internal Vcc approx. 10 V *** Only one of both signals possible, see section 3.5.3.1 **** Only during remote control ***** The error of a set value input adds to the general error of the related value on the DC terminal of the device 3.6.4.5 Overview of the Sub-D socket 3.6.4.
PSB 9000 2.5 kW Series Following situations can occur: • Remote control has been activated During remote control via analog interface, only pin “REM-SB” determines the states of the DC terminal, according to the levels definitions in 3.6.4.4. The logical function and the default levels can be inverted by a parameter in the setup menu of the device. See 3.5.3.1. If the pin is unconnected or the connected contact is open, the pin will be HIGH.
PSB 9000 2.5 kW Series c) Reading actual values The AI provides the DC terminal values as current and voltage monitor. These can be read using a standard multimeter or similar. d) Switching between source and sink mode You can also switch between both modes when remotely controlling the device with the AI. This is done using the voltage set value (VSEL), which then must not be tied to a fixed potential, like shown in example b).
PSB 9000 2.5 kW Series 3.7 Alarms and monitoring 3.7.1 Definition of terms There is a clear distinction between device alarms (see „3.4. Alarm conditions“) such as overvoltage protection or overheating protection, and user defined events such as OVD (overvoltage detection).
PSB 9000 2.5 kW Series These device alarms can’t be configured and are based on hardware: Short Long Description Indication PF Power Fail AC supply over- or undervoltage. Triggers an alarm if the AC supply is out of specification or when the device is cut from supply, for example Display, analog & when switching it off with the power switch. The DC terminal will be digital interface switched off. OT OverTemperature Triggers an alarm if the internal temperature reaches a certain limit.
PSB 9000 2.5 kW Series These events shouldn’t be confused with alarms such as OT and OVP which are for device protection. User defined events can, however, if set to action ALARM, switch off the DC terminal and thus protect the load, like a sensitive electronic application. ►►How to configure user defined events 1. While the DC terminal is switched off tap the touch area on the main screen. 2. On the right side tap the arrows 3. to select “7.1 Event U Src” or “7.2 Event I Src” or “7.
PSB 9000 2.5 kW Series 3.9 Limits lock In order to avoid the alteration of the adjustment limits (also see „3.5.4. Adjustment limits“) by an unprivileged user, the screen with the adjustment limit settings (“Limits”) can be locked by a PIN code. The menu pages for the limits in SETTINGS and the profiles in MENU will then become inaccessible until the lock is removed by entering the correct PIN or in case it has been forgotten, by resetting the device as last resort. ►►How to lock the “Limits” 1.
PSB 9000 2.5 kW Series 3.11 The function generator 3.11.1 Introduction The built-in function generator (short: FG) is able to create various signal forms and apply these to the set value of either voltage or current. The standard functions are based on an arbitrary generator and directly accessible and configurable using manual control. In remote control, the fully customizable arbitrary generator replicates these functions with sequence points containing 8 parameters each.
PSB 9000 2.5 kW Series 3.11.2.3 Resolution Amplitudes generated by the arbitrary generator have an effective resolution of approx. 52428 steps. If the amplitude is very low and the time long, the device would generate less steps and set multiple identical values after another, generating a staircase effect. It’s furthermore not possible to generate every possible combination of time and a varying amplitude (slope). 3.11.2.
PSB 9000 2.5 kW Series 3.11.4 Manual operation 3.11.4.1 Function selection and control Via the touch screen one of the functions described in 3.11.1 can be selected, configured and controlled. This is only permissible while the DC terminal is switched off. ►►How to select a function and adjust parameters 1. While the DC terminal is switched off tap the touch area on the main screen. 2. In the menu tap on the touch area 3. and then on the desired function.

PSB 9000 2.5 kW Series 3.11.14 FC table function (fuel cell) 3.11.14.1 Preface The FC table function is used to simulate the characteristics of voltage and current of a fuel cell. This is achieved by setting up some parameters which define points on a typical fuel cell curve, which is then calculated as UI table and passed to the internal function generator. The user has to adjust value for four support points.
PSB 9000 2.5 kW Series The function can be saved to USB stick as table, as well as read via any of the digital interfaces. In remote control, the function can’t be loaded or controlled. From the screen where the XY function generator is controlled manually (start/stop), you can go back to the first screen of the FC table function and use the formerly locked touch area to save the table to USB drive. In order to do so, follow the on-screen instructions.
PSB 9000 2.5 kW Series 3.11.15.4 Simulation mode Apart from the panel technology there is also a simulation mode to select. Four options: Mode U/I Controllable simulation. Voltage (UMPP, in V) and current (IMPP, in A) in the maximum power point (MPP) are variable during runtime. The purpose of this mode is to directly shift the MPP into various directions. Mode E/T Controllable simulation.

PSB 9000 2.5 kW Series Step 4: Global limits This configuration screen allows to limit voltage and power globally for the simulation. The current, in this table based simulation, is taken from the calculated PV table which also is an IU table. The output voltage of the power supply is already defined by setting up UOC in step 2, so it’s recommended to adjust value U to same or higher, else the PV curve may not be working as expected. The power shouldn’t be limited at all.
PSB 9000 2.5 kW Series 3.11.16 Battery test function The purpose of the battery test function is to charge and discharge various battery types in industrial product tests or laboratory applications. Additionally, the so-called dynamic test mode combines a certain flow of charge and discharge phases while offering full configurability, for example which phase starts first or how much time in between both (pause) phases has to elapse or how often the charge/discharge cycle is going to be repeated.
