Using the power supply

Example applications
Overview D-Sub socket
Attention! Never connect grounds of the analogue interface
to minus (negative) output of an external control application
(PLC, for example), if that control application is otherwise
connected to the negative power supply output (ground
loop). Load current may flow over the control leads and
damage the device!

Output off
Pin „REM-SB“ is always operative and does not depend on
the remote mode. It can thus be used to switch off the output
without extra means.
All the user has to do is to ensure the level of the input is held.
Remote control of current and voltage
Two potentiometers between VREF and ground, sliders at the
inputs VSEL and CSEL. The power supply can be controlled
as with the rotary knobs on the front and can either operate as
current or voltage source. In compliance with the max. 3mA for
the VREF output, potentiometers with at least 10kOhm have
to be used.
The power set value is here, for models with power regulation
feature, tied to VREF and thus 100%.
or
Remote control with power (where available)
Similiar to the example above, but with adjustable power limit.
Power adjustment only works at models from 1000W, which
feature power regulation.
