Local / Remote control
The LED “Remote” illuminates, when the Power Supply is in the REMOTE control mode and
is off in LOCAL control mode.
The control mode (LOCAL/REMOTE) is changed by pushing the "Remote" push button if the

Current setting
In local:
The output current level can be displayed by pushing the “SET” button.
The output current display consists of six 7-segment LEDs. The left segment shows the sign. For
negative set values a minus sign will be displayed and for positive set values no sign will be
displayed. The other Segments display the set value. Each segment can be altered individually
with the up/down button. To select which segment to alter, use the forward/back button. The
chosen segment will flash.

Setting up the MPS
Two dip-switches are available for setting up of the power supply.
35V / 75V setup
The analogue ±10V output voltage read back can be scaled for either 35V or 75V
Factory settings are indicated on the back of the SYSTEM 7000 cabinet

Bandwidth setup
For highest stability and fastest response time, the load impedance transfer function is incorporated
in the total loop gain. Therefore it is necessary to adapt the internal gain and frequency response of
the loop to match the actual connected load.
The current loop gain can be change between 1, 5 and 10 on switch P302. (1, 14 and 20dB)
The lowest loop pole can be shifted a decade upwards with switch P306.
