SYSKON⏐P1500
Computer Controlled Laboratory Power Supply
Front Panel Control Disabling
The controls can be disabled to prevent unauthorized operation
by pressing the appropriate key, with a computer command or by
applying a signal to the trigger input.
Analog Control Inputs
Voltage and current can also be adjusted by via the control inputs
at the analog interface. A 5 V signal corresponds to 100% of the
respective nominal value.
These inputs can be switched on and off using the keys, or with
computer commands.
The controlled output quantity is the sum of the digital setpoint
value and the specified value at the control input.
This function makes it possible to superimpose these control
signals onto the output quantities.
Monitor Outputs
The actual values for output voltage and current can be
acquired at the monitor outputs as a standardized signal (10 V
corresponds to 100% nominal value).
Trigger Inputs
Two floating trigger inputs are available for controlling device
functions. The following trigger input assignments can be
selected:
– output = Switch the power output on and off
– local lock = Disable controls
– SQS = (sequence step) Step-by-step control of a
stored sequence
– sequence = Start / stop the sequence function
–
Analog input = Activate / deactivate the analog control inputs
Signal Outputs
Programmable Control Outputs
The analog interface is equipped with three digital control outputs
for status messages to external monitoring devices, for switching
external components on and off, or for coupling purposes.
The status of these outputs can be defined either directly, or
depending upon the following device statuses:
– Output on or off
– Voltage or current regulation
– Sequence function running or finished
– SSET signal status for the sequence function
– Limit value message for the measuring function (tolerance
band)
Min-Max Measured Value Memory
The Min-Max function automatically acquires and saves minimum
and maximum voltage and current values.
Tolerance Band (in combination with Min-Max function)
Measured output values can be continuously compared with
stored upper and lower tolerance band values. Evaluation is
possible via the programmable control outputs.
Memory
The memory function makes it possible to save and recall device
configurations using a battery-backed memory module.
The memory module is equipped with two storage areas:
– Setup memory: 12 memory locations for complete
configurations
– Sequence memory: 1536 memory locations for the following
sequence parameters: voltage setpoint USET, current set-
point ISET, dwell time TSET and function request FSET, with
the ability to invoke subsequences
Sample Application
Generation of a characteristic voltage curve in an automotive
electrical system when starting the engine
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.
DKD Calibration Certificate
All SYSKON Konstanters are shipped with a DKD calibration cer-
tificate (DKD = Deutscher Kalibrierdienst; German calibration
authority) issued by our DKD test laboratory.
Operating Software for Computer Controlled Systems
Convenient software in English for quick and easy use of the
SYSKON KONSTANTER is available free of charge. Its central ele-
ment is the Soft Front Panel. This makes it possible for the user to
take targeted advantage of the comprehensive range of included
functions within his own application – without any programming at
all. The panel has a clear-cut layout and is broken down into
taskspecific displays.
The software detects KONSTANTERs which are connected to the
various possible interfaces including USB, RS 232 and GPIB.
KONSTANTERs detected by the software are identified automati-
cally and can be selected for the respective application.
If several KONSTANTERs are connected, the software can be
started separately for each device, and each device can be indi-
vidually controlled.
