3 Technical Description Description SYSKON KONSTANTERs (power factor control, single-output system power supplies) are manual and remote controllable DC power supplies for laboratory and system use. Thanks to modern switching controller technology, the devices are compact and lightweight despite high output power. Active power factor control assures nearly sinusoidal mains input current.
Performance After Power on Analog Control Inputs In the event of mains failure, it’s important to specify which operating state the device will assume when power is restored. This may be extremely important if the device is used in long-term testing applications.
Sample Application Generation of a characteristic voltage curve in an automotive electrical system when starting the engine U [V] 12 6 4.5 5 15 5 2000 10 t [ms] Note: Compliance with voltage rise and drop times is only assured within a limited load impedance range. Balancing Function (adjust) Offset and final values for setting and measured values for output quantities voltage and current are balanced digitally in the device. The user can execute balancing as required with this function.

7.2 Auto-sensing mode Function Output voltage values required for voltage measuring and control circuits can be acquired directly at the consumer instead of at the output terminals with the help of the SENSE + and SENSE – sensing lead terminals at the analog interface. Sensing mode operation (remote sensing) offers the following advantages: • In the constant voltage regulating mode, current related voltage drops occurring in the output leads have practically no effect on voltage supplied to the consumer.

• Usi can also be applied as an alternating voltage, for example in order to superimpose manually selected direct current ISET with interference signals. To a great extent, the maximum operating frequency of modulated output current depends upon the output current value, as well as the voltage amplitude which results from the prevailing load, and thus cannot be defined with a simple formula. It is increased as amplitude is decreased, and as load is increased.
7.8 Trigger Inputs Trigger Function Setting Parameters Function • • Floating optocoupler inputs TRG 1± and TRG 2± allow for remote control of a device function with the help of a binary signal. The function to be controlled is selected by manually or digitally configuring the trigger mode (SEtUP/dPYIF/AnIF/trG 1 txt or SEtUP/dPYIF/AnIF/trG 2 txt). Parameters Meaning OFF Trigger input function is deactivated, trigger signals have no effect.
7.9 Parallel Connection • If output current from a single KONSTANTER is insufficient for the respective application, the outputs of any number of KONSTANTERs can be parallel connected. ! This output maintains constant load current until the load resistor is short-circuited. Attention! If outputs with different nominal voltages are parallel connected, all outputs must be limited to the lowest utilized nominal voltage value. The ULIM parameter is used to select this setting. 7.9.
7.9.2 Master-Slave Parallel Connection Function As opposed to direct parallel connection, master-slave parallel connection offers significant advantages: • Equally suitable for voltage and current regulation • Output parameters (output voltage, cumulative current limiting) are set entirely by the master device. • All interconnected KONSTANTERs are equally loaded. Wiring • • • • Define one power supply as a master device. Connect master and slave devices as shown in figure 7.9.2. Connect the output leads.
7.10 Series Connection If output voltage from a single KONSTANTER is insufficient, or if you want to generate a ± voltage, the outputs of several KONSTANTERs can be connected in series. Warning! Maximum allowable cumulative voltage for series connection is 240 V (or 480 V with grounded neutral point). 7.10.1 Direct Series Connection ! Attention! If outputs with differing nominal values are series connected, the highest selected current value is present at all outputs in the event of short-circuit.
7.10.2 Master-Slave Series Connection Function As opposed to direct series connection, master-slave series connection offers significant advantages: • Equally suitable for voltage and current regulation • Output parameters (cumulative output voltage, current limiting) are set entirely by the master device. • All interconnected KONSTANTERs are equally loaded. Wiring • • • • Define one power supply as a master device. Connect master and slave devices as shown in figure 7.10.2.
7.11 Varying the Internal Output Resistance Value Function In the voltage regulating mode, internal output resistance has a value of close to 0 Ω. The internal output resistance value can be increased for certain applications, for example simulation of long output cables or weak automotive batteries. The selected (open-circuit) output voltage is reduced in proportion to increasing load (figure 7.11 a) Figure 7.
8 Descriptions of Operating Commands All setting and query commands are described and listed alphabetically in the following pages. Commands with an asterisk (*) are at the beginning of the list. Each heading includes the command, along with its abbreviation. Insofar as query commands exist (identified with a question mark ?), they are listed as well. The next line (with the hand symbol) indicates how the respective command can be executed manually. If keys are required, they are mentioned as well.
*ESE, *ESE?, *PRE, *PRE?, *SRE, *SRE?, ERAE, ERAE?, ERBE, ERBE?, ERCE, ERCE? – Enable registers — Function The enable registers determine which bit(s) from the corresponding event or status byte register is/are capable of influencing the respective group message. The respective group message remains set (1 = TRUE), as long as at least one bit which has been enabled to this end has a status of TRUE.
*OPC, *OPC? – Operation Complete Query — *RCL – Recalling Stored Settings RCL Function The operation complete function (OPC) allows for synchronization of the controller and the device: Information indicating whether or not the previous instructions in the command string have been processed can thus be evaluated. There are two possible procedures: Function Settings which have been previously saved to battery-backed memory with the *SAV command (SAVE) can be recalled and activated with *RCL (RECALL).
*SAV – Saving Device Settings SAVE *TRG – Device Trigger Function — Function Current device settings can be saved to battery-backed memory with the *SAV (SAVE) execution command. Function A command or a list of commands which has been previously defined by means of the *DDT string (DEFINE DEVICE TRIGGER) is executed with this command. The device accepts this command as a device message via all integrated PC interfaces.
connected to a suitable resistive load for current balancing. ADJUST – Balancing / Calibration Function Menu ! Function ! Attention! This procedure replaces directly the reference parameters referring to the accuracy of the Konstanter. Please check carefully before starting this procedure. The factory settet adjustment was done with high precise instruments as shown in DKD-calibration certificate. When starting the adjust function, the right display shows the last presetted calibration date (format Y.
C_DYN, C_DYN? – Setting Current Regulating Dynamics Menu DCL, SDC – Device Clear Function — Function This command makes it possible to adapt the control dynamics of the current regulator to inductive loads. Correct use of this command allows for optimization of the regulator for critical load circumstances. Function The device clear command causes clearing of the input and output buffers at the computer interfaces (e.g. requested data which have not been picked up).
Parameters List ERROR? – List of Error Messages Menu Param- Content Meaning eter Function The three last different error messages can be read out with this command. The content of the µC-RSTSRC registers is added as the fourth parameter The error list can be reset with the *CLS command. A description of the errors is included in the section entitled “System Messages”. CLR Empty memory location, is ignored/skipped during execution.
IL_H, IL_H? – Upper Limit Value for Current Setting Menu IMAX? – Maximum Measured Current Value Menu Function IL_H defines the upper setting limit (soft-limit) for current setpoint value Iset. The limit can be used to assure that output current is not inadvertently set above a specified value. The IL_H command corresponds to the ILIM command for the SSP6XN Konstanter series as an upper limit value. Thus IL_H can also be replaced with ILIM. When the ILIM? query is executed, IL_H +XXX.
ISET, ISET? – Current Setpoint SELECT B or rotary encoder Iset Function The output current setpoint is set with ISET. The ISET? query returns the momentarily selected current setpoint as a response. Values outside of the value range (0 ≤ IL_L ≤ w ≤ IL_H ≤ Inom) are not accepted, and cause generation of an error message and setting of an error bit in event register ERC.2. Entered numeric values are rounded off to device-specific resolution.
OCP, OCP? – Overcurrent Protection Menu, LED OC_DELAY, OC_DELAY? – Overcurrent Protection Trigger Delay Menu Function The OCP function (over current protection) determines how the power output will respond if load current climbs to the selected OCSET value. The OCP function is used in addition to current regulation, whose setpoint is specified with ISET or via the analog control input.
OUTPUT, OUTPUT? – Switching the Power Output On and Off OUTPUT / LED OVP, OVP? – Overvoltage Protection Menu, LEDs Function The power output can be activated and deactivated with the OUTPUT function. Activation: OUTPUT ON: Current and voltage values of “0” are specified initially for a period of approximately 2 ms with activated output for the transition from the “highly resistive” condition. The output is then adjusted to the selected voltage and current setpoints.
OVSET, OVSET? – Overvoltage Protection Trigger Value SELECT A and Menu POWER_ON, POWER_ON? – Response After Power On Menu Function The triggering threshold reference value required for the OVP function is set with OVSET. Function The POWER_ON function determines the status of device settings after mains power has been switched on.
REPETITION, REPETITION? – Number of Repetitions for Sequence Function Menu Function The REPETITION parameter determines how many times a sequence will be repeated, which is defined by the current START and STOP addresses. It is an optional parameter which addresses the setup memory (1 to 12) to which the repetition value will be written, and from which it will be read.
SIG123, SIG123? – Analog Interface Signal Outputs Menu SM_LOAD – Load Sequence Memory Location Menu Function Two floating signal outputs (SIG 1 and SIG 2) and one signal output with reference to AGND 2 (SIG 3) are provided at the analog interface. They can be used to trigger control functions in the application. Different device functions and statuses can be assigned to these signals. Function The content of a memory location can be loaded in a targeted fashion with the SM_LOAD command.
START_STOP, START_STOP? – Memory Location Start and Stop Addresses for the Sequence Function Menu Function The start and stop addresses of the sequence to be executed are defined with the START_STOP command. The STOP address must be equal to or greater than the START address. i is an optional parameter which addresses the setup memory (1 to 12) to which the START-STOP values will be written, and from which they will be read.
T_MODE, T_MODE? – Function Selection for the Trigger Inputs Menu Function Two floating trigger inputs are provided at the analog interface, whose action can be defined independent of each other. In this way, control functions can be triggered at the device from the application. Depending upon which function is selected, the trigger input is level or edge controlled. Note: Detailed descriptions of the control level are included in the section entitled “Analog Interface”.
UL_L, UL_L? – Lower Limit Value for Voltage Setting Menu UOUT? – Querying the Momentary Voltage Value SELECT A Function UL_L defines the lower setting limit (soft-limit) for voltage setpoint value Uset. The limit can be used to assure that output voltage is not inadvertently set below a specified value. Values outside of the value range (0 ≤ w ≤ Uset) are not accepted, and cause generation of an error message and setting of an error bit in event register ERC.2.
9 Status and Events Management The device is equipped with special registers which can be queried by the controller in order to detect programming errors (e.g. receipt of an incorrect command), device states (e.g. output set to voltage regulating mode) or occurred events (e.g. output deactivated by a protective function).
