● Switch on delay
In order to reduce the load on the overall SITOP PSU8600 power supply system as a
result of simultaneous switch-on current peaks of the loads at the various outputs, an on
delay between the outputs can be selected when switching on.
When the on delay is activated, the outputs are sequentially switched-on with a 25 ms or
100 ms delay time between the outputs, or load optimized.
When the variable on delay is activated, you can assign individual on delay times to the
individual outputs.
● Mode
Two overload responses can be defined for all outputs:
–
In the ELECTRONIC SHUTDOWN mode, overload is permitted for a defined time.
The output is electronically shut down after the limit value has been exceeded (see
Overload shutdown and carrying out a reset (Page 56)).
– In the CONSTANT CURRENT mode, an overload current is continually permissible
(U/I curve) according to a defined characteristic. The overload current is limited to a
maximum of 150 % of the setting value of the current potentiometer for a duration of 5
seconds (LED "ON/OFF/RST" flashes green with 2 Hz); the current is then limited to
100 % of the setting value (LED "ON/OFF/RST" flashes green with 1 Hz) as long as
there is an overload condition.
You can find additional information on configuring the outputs in Chapter Operator control at
the device (Page 51).
