Protective and Additional Functions
– Sensor terminals protected against pole reversal
with automatic switching to sensing mode (auto-sensing)
– Protection against excessive temperature
– Protection against output pole reversal
– Locking of front panel operation
– Device configuration memory with battery backup
– Power and phase failure recognition
– In-rush current limiting
Auto-Sensing
Operation in the sensing mode (remote sensing) can be activated
in order to compensate for voltage drops at the power lines.
The sensing mode is automatically activated by connecting the
(–) negative sensing terminal to the negative load level.
Max. compensatable
voltage drop 1 V per line
Locking of Front Panel Operation
The control elements can be secured against unauthorized use by
pressing a key, with a computer command, or by applying a
signal to the trigger input.
Activating and Deactivating the Output
The power output can be activated and deactivated by pressing a
key, with a computer command, or by applying a signal to the
trigger input (no electrical isolation).
Power-On Status
The power supply can be placed into one of the following
conditions after power-up:
– Reset = default setting (0 V, 0 A, output inactive etc.)
– Recall = last setting (same as prior to last shutdown)
– Standby = last setting, but with inactive output
Overcurrent Protection
The device can be configured to respond to current limiting in one
of the following ways:
– OCP off = continuous current limiting (UI characteristic curve)
– OCP on = deactivate output if duration of current limiting
is greater than delay time
Delay time: setting range from 0.00 to 99.99 s
resolution: 10 ms
Trigger Selection
The device can be configured to respond to the floating trigger
input at the analog interface in one of the following ways:
– output = activate / deactivate the power output
– local lock = lock the control elements
– recall = individual, step-by-step recall of stored
settings
– sequence = start / stop the sequence function
