Operating the device

9. Digital interface cards

The device supports following retrofittable, pluggable, digital
interface cards:
IF-U1 (USB)
IF-R1 (RS232)
IF-C1 (CAN)
IF-G1 (GPIB/IEEE)
IF-E1 (Ethernet/LAN)
IF-PB1 (Profibus)
The cards require only a little or no setup after insertion. The
card specific settings are kept, even if the card is replaced by
one of different type. Thereby it is not necessary to configure
the card settings everytime a card is inserted.
Details about the technical specs of the interface cards and the
handling, as well as instructions to implement the device into a
bus system or to control the device by means of a PC (LabView
etc.) can be found in the user manual for the IF cards.
Important! Insertion or removal only if the device is completely
switched off (power switch)!
About configuration of the plugged cards see section „8. Device
setup".

10. Analogue interface

10.1 General

The integrated, 15 pole analogue interface is located on the
front and offers, amongst others, following possibilities:
• Remote control of output current, voltage and power
• Remote monitoring of status (OT, OVP, CC, CV)
• Remote monitoring of actual values
• Remotely switching the output on/off
The control voltage range that is going to be used is selected in
the device setup. See section „8. Device setup". The reference
voltage at output pin 3 is related to the chosen setting and will
be either 5V or 10V.
Usage instructions:
• Controlling the device with analogue voltages requires to
switch it to remote control with pin „REMOTE" (5).
• Before connecting the application that is used to control the
power supply, make sure to wire all leads correctly and check
if the application is unable to put in voltages higher than
specified (max. 12V).
• The input REM-SB (remote standby, pin 13) overrides the
pushbutton Output On. It means, the output can not be swit-
ched on by the button if the pin defines the output state as „off".
• The output VREF can be used to build set values for the set
value inputs VSEL, CSEL and PSEL. For example, if only
current control is required, pin VSEL and PSEL can be brid-
ged to VREF. CSEL is then either fed by an external voltage
(0...5V or 0...10V) or via a potentiometer between VREF and
ground. Also see next section.
• Putting in set values up to 10V while the 0...5V range is se-
lected will ignore any voltage above 5V (clipping) and keep
the output value at 100%.
• The grounds of the analogue interface are related to
minus output.

10.2 Pin overview

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!
