Therefore all parts under voltage must be covered! This basically applies to all models, though 40 V models according to SELV can not generate hazardous DC voltage! • All work on connections must be carried out under zero voltage (output not connected to load) and may only be performed by qualified and informed persons.
PS 9000 3U Series 1.7.2 Responsibility of the user The equipment is in industrial operation. Therefore the operators are governed by the legal safety regulations. Alongside the warning and safety notices in this manual the relevant safety, accident prevention and environmental regulations must also be applied.
PS 9000 3U Series 1.7.5 Alarm signals The equipment offers various possibilities for signalling alarm conditions, however, not for danger situations. The signals may be optical (on the display as text) acoustic (piezo buzzer) or electronic (pin/status output of an analog interface). All alarms will cause the device to switch off the DC output.

PS 9000 3U 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 signals or switching conditions. If remote control is in operation this analog interface can only be used alternately to the digital interface. However, monitoring is always available.
PS 9000 3U 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 output terminal, rotary knobs).
PS 9000 3U Series 2.3.2 Preparation Mains connection for the PS 9000 3U series is done via the included 5 pole plug on the back of the device. Wiring of the plug is at least 3 wire (L2+L3+PE) or, for some models, 4 wire (L1+L2+L3+PE) of suitable cross section and length. It’s allowed to wire the N conductor of a standard three-phase cable to the remaining input pin. For recommendations for cable cross section see „2.3.4. Connection to AC supply“.
PS 9000 3U Series 2.3.4 Connection to AC supply • Connection to an AC mains supply may only be carried out by qualified personnel! • Cable cross section must be suitable for the maximum input current of the device (see table below)! • Before plugging in the input plug ensure that the device is switched off by its mains switch! 2.3.4.1 Models for 400 V The device is delivered with a 5 pole AC plug.
PS 9000 3U Series 2.3.4.2 Models for 208 V The equipment is delivered with a 4 pole mains plug. Depending on model, this will be connected with a 2-phase or 3-phase mains supply, which has to be connected according to the labelling on the plug and the table below.
PS 9000 3U Series 2.3.4.3 Connection variants Depending on the max. output power of a certain model, it requires two or three phases of a three-phase AC supply. In case multiple units with 3.3 kW to 10 kW power rating are connected to the same AC supply point, it is recommended to take care for balanced current distribution on the three phases. See table in 2.3.4 for the max. phase currents. The 15 kW models are an exception, because they already consume balanced current on all three phases they require.
PS 9000 3U Series 2.3.5 Connection to DC loads • In the case of a device with a high nominal current and hence a thick and heavy DC connection cable it is 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 hangs on the DC output, a strain reliever should be used.
PS 9000 3U Series Examples of the type 1 terminal: • 90° up or down • space saving in depth • no bending radius • horizontal lead • space saving in height • large bending radius 2.3.6 Connection of remote sensing In order to compensate, to a certain degree, the voltage loss in a DC cable, the device provides the possibility to connect the remote sensing input “Sense” to the load.
PS 9000 3U Series 2.3.7 Grounding of the DC output Grounding one of the DC output poles is allowed. Doing so results in a potential shift of the other pole against PE. Because of insulation, there is a max. allowed potential shift of the DC output poles, which also depends on the device model. Refer to the technical specifications. 2.3.

PS 9000 3U Series 3. Operation and application 3.1 Important notes 3.1.
PS 9000 3U Series 3.2.2 Current regulation / constant current / current limiting Current regulation is also known as current limitation or constant current mode (CC). The DC output current is held constant by the power supply as soon as the output current flowing to the load reaches the adjusted current set value. The actual current results from the output voltage and the load’s true resistance.
PS 9000 3U Series 3.3 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 „3.6. Alarms and monitoring“. As a basic principle, all alarm conditions are signalled optically (Text + message in the display), acoustically (if activated) and as a readable status via the digital interface. With any alarm occurring, the DC output of the device is switched off.
PS 9000 3U Series 3.4 Manual operation 3.4.1 Switching the device on 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 show the manufacturers logo for a few seconds, plus some information like device model, firmware version(s), serial number and item number and will then be ready for use.
PS 9000 3U Series 3.4.3.1 Menu “General Settings” Element Description Allow remote control Selection “NO” means that the device can’t be remotely controlled over any of 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. Also see section 1.9.6.1 Analog interface range Selects the voltage range for the analog set input values, actual output values and reference voltage output of the analog interface on the rear.
PS 9000 3U Series Element Description DC output after OT alarm Determines how the DC output shall react after an overtemperature alarm has occurred: • OFF = DC output will be switched off and remain until user action • AUTO = DC output will switch on again after the device has cooled down and if the output has been switched on before the alarm occurred Share Bus mode Default setting: Slave For parallel operation of multiple units, where using the Share bus connection is recommended.
PS 9000 3U Series Submenu “IP Settings 1” Element Description Get IP address Manual (default): uses the default (after delivery or reset) or the last set network parameters. Those parameters are not overwritten by selection “DHCP” and remain when switching back from “DHCP” to “Manual” DHCP: after switching to DHCP and submitting the change with button , the device will instantly try to get network parameters (IP, subnet mask, gateway, DNS) assigned from a DHCP server.
PS 9000 3U Series Screen “View settings” This screen lists an overview of all active network and Ethernet port related settings and parameters, the status of DHCP, the MAC address and also the domain and host name, which can’t be set in the device’s setup menu. 3.4.3.7 Menu “HMI Setup” These settings refer exclusively to the control panel (HMI) and the display. The table lists all available settings for the HMI, no matter in which sub menu they can be found.
PS 9000 3U Series 3.4.4 Adjustment limits By default, all set values (U, I, P) are freely adjustable from 0 to 102% of rated value. This may be obstructive in some applications, especially for protection of applications against overcurrent. Therefore upper and lower limits for current and voltage can be set which limit the range of the adjustable set values. For power only an upper value limit can be set. These limits apply to every kind setting a value.
PS 9000 3U Series 3.4.5 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 usually assigned two of the three values in manual operation. Default assignment is voltage and current. The set values can only be adjusted with the rotary knobs. Entering a value changes it at any time, no matter if the output is switched on or off.
PS 9000 3U Series 3.4.7 The quick menu The quick menu offers access to some feature which are also accessible from the regular menu, but here they can be used while the DC output is switched on. The quick menu is shown when pressing the button and looks like this: Navigation in the menu is also done with arrow buttons / and . For example, in this menu it’s possible to preset the output values and to submit with button which allows for set value steps which would not be possible when rotating a knob.
PS 9000 3U Series 3.5 Remote control 3.5.1 General Remote control is principally possible via any of the built-in interface ports USB, Ethernet/LAN, analog or optional GPIB. Important here is that only the analog or any digital interface can be in control. It means that if, for example, an attempt were to be made to switch to remote control via the digital interface whilst analog remote control is active (pin REMOTE = LOW) the device would report an error at the digital interface.
PS 9000 3U Series 3.5.4 Remote control via the analog interface (AI) 3.5.4.
PS 9000 3U Series 3.5.4.3 Acknowledging device alarms In case of a device alarm occurring during remote control via analog interface, the DC output will be switched off the same way as in manual control. The device would indicate an alarm (see 3.6.2) in the front display and, if activated, acoustically and also signal most of them on the analog interface. Which alarms actually are signaled can be set up in the device configuration menu (see „3.4.3.1. Menu “General Settings”“).
PS 9000 3U Series 3.5.4.5 Overview of the Sub-D Socket 3.5.4.6 Simplified diagram of the pins Digital Input (DI) + 4K7 +10V 3.5.4.7 Analog Input (AI) The DI is internally pulled up and thus it requires to use a contact with low resistance (relay, switch, contactor etc.) in order to clearly pull the signal down to DGND. 12V V~0.5 High resistance input (impedance >40 k....100 kΩ) for an operational amplifier circuit.
PS 9000 3U Series • Remote control isn’t active In this mode of operation pin “REM-SB” can serve as lock, preventing the DC output from being switched on by any means. This results in following possible situations: DC output + + is off + Level on pin REM-SB HIGH LOW HIGH LOW + + + + + Parameter „Analog Behavior interface REM-SB“ DC output not locked. It can be switched on by pushbutton “On/Off” Normal (front panel) or via command from digital interface.
PS 9000 3U Series 3.6 Alarms and monitoring 3.6.1 Definition of terms Device alarms (see „3.3. Alarm conditions“) are defined as conditions like overvoltage or overtemperature, signalled in any form to the user of the device in order to take notice. Those alarms are always indicated in the front display as readable abbreviated text, as well as status readable via digital interface when controlling or just monitoring remotely and, if activated, emitted as audible signal (buzzer).

In case the additional PIN code lock has been activated in the menu “HMI Lock”, another requester will pop up asking you to enter the PIN before it finally unlocks the HMI. 3.
PS 9000 3U Series 3.9 Other applications 3.9.1 Parallel operation in Share bus mode Multiple devices of same kind and model can be connected in parallel in order to create a system with higher total current and hence higher power. To achieve that, the units have to be connected on their DC outputs and their Share Bus. The Share Bus will balance the units in their internal voltage regulation and thus current regulation, which will result in a balanced load distribution.
PS 9000 3U Series 3.9.1.5 Alarms and other problem situations Parallel operation, due to the connection of multiple units and their interaction, can cause additional problem situations which do not occur when operating individual units. For such occurrences the following regulations have been defined: • If one or more slave units are switched off on the AC side (power switch, supply undervoltage) and come back later, they’re automatically included again in the system.
PS 9000 3U Series 3.9.4 Two quadrants operation (2QO) 3.9.4.1 Introduction This way of operating refers to the use of a source, in this case a power supply of series PS 9000 3U (only from revision 2, see type label), and a sink, in this case a series ELR 9000 or series EL 9000 B electronic load. The source and the sink function alternatingly in order to test a device, such as a battery, by deliberately charging and discharging it as part of a functional or final test.
PS 9000 3U Series 3.9.4.3 Settings on the devices The master-slave settings in the MENU of the load device(s) also affect the Share bus. For correct 2QO operation, all involved load units must be slaves on the Share bus. This is achieved by setting the master-slave mode to OFF or SLAVE, depending on if there is digital master-slave in use or not. For the one load that is master (setting: MASTER) in the master-slave system the additional parameter “PSI/ELR system” resp. “PSI/EL system” has to be activated.
PS 9000 3U Series 4. Service and maintenance 4.1 Maintenance / cleaning The device needs no maintenance. Cleaning may be needed for the internal fans, the frequency of cleanse is depending on the ambient conditions. The fans serve to cool the components which are heated by the inherent power loss. Heavily dirt filled fans can lead to insufficient airflow and therefore the DC output would switch off too early due to overheating or possibly lead to defects.
PS 9000 3U Series 4.3 Calibration (readjustment) 4.3.1 Preface The devices of series PS 9000 feature a function to re-adjust the most important DC output related values, which can help in case these values are out of tolerance. The procedure is limited to compensate small differences of up to 1% or 2% of the ratings. There are several reasons which could make it necessary to readjust a unit: component aging, component deterioration, extreme ambient conditions, high frequent use.
PS 9000 3U Series 4.3.3.1 Calibrating the set values ►►How to calibrate the DC output voltage 1. Connect a multimeter to the DC output. Connect a load and set it to approx. 5% of the nominal current of the power supply as load current, in this example ≈8 A. 2. In the display enter the setup menu with button , then push . In the sub menu navigate to “Calibrate Device”. Push 3. In the next screen select “Voltage calibration” + 4. 5. again. , then “Calibrate output value” + 2x .
PS 9000 3U Series 4.3.3.3 Calibrating the actual values Actual values of output voltage (with and without remote sensing) and output current are calibrated almost the same way as the set values, but here you don’t need to enter anything, just confirm the displayed values. Please proceed the above steps and instead of “Calibrate output value” select “Calibrate actual value” in the submenus.
