Operating the device
9. Pluggable interface cards
9.1 General
The power supply supports various optionally available inter-
face cards for digital or analogue remote control. All cards are
galvanically isolated. Following isolation voltages are given:
• USB (IF-U1), CAN (IF-C1), RS232 (IF-R1): 2000V DC
• GPIB (IF-G1): 2000V DC
• Ethernet (IF-E1b): 1500V DC
• Extended analogue interface (IF-A1): 2000V DC
Note: before picking an interface for remote control, consi-
der the isolation voltage and carefully check if the particular
isolation voltage is sufcient for the target application!
The digital interface cards IF-R1 (RS232), IF-C1(CAN) and IF-
U1(USB) use a uniform communication protocol. Up to 30 units
can be controlled from a PC at once with these cards.
The GPIB interface IF-G1 (IEEE 488) offers a SCPI command
structure for up to 15 units per bus.
The Ethernet/LAN interface IF-E1 also provides SCPI command
set, as well as a browser surface. It features an additional USB
port which makes the device accessible like with the IF-U1 card.
The interface card IF-A1 is an extended analogue interface,
which features a higher isolation voltage than the built-in analo-
gue interface, as well as variable input voltage range and much
more. For more information, please refer to the interface cards
instruction manual, which is supplied on the CD that is included
with the interface or available upon request or on our website.
9.2 Conguring the interface cards
The interface card is automatically recognized by the power
supply and should be congured at least once.
This is done using the menu Communication.
+Communication +
Except for the optional analogue interface IF-A1 it is recom-
mended to set the unit’s address (Device node). Only then
the units can be identied correctly in case multiple units are
connected to the PC. Select the interface with
Slot A: { IF-… } (depends on what is equipped)
Then you can adjust the device node:
Device node Default: 1
= {1..30} Up to 30 device nodes (addresses) can be as-
signed to devices, one per unit. A device node
must only be assigned once if multiple units are
controlled.
Conguring the various cards
All cards have different parameters to congure. These are
explained in detail in the corresponding user instruction manual.
Please refer to it.
10. Built-in analogue interface
10.1 General
The integrated, galvanically isolated (for isolation voltage see „2.
Technical specications“), 15 pole analogue interface is located
on the rear and offers following features:
• 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 set value inputs can be operated with either 0...5V or
0...10V. The desired voltage range is selected in the device
setup (see section 10.3).
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
specied (max. 12V).
• The input REM-SB (remote standby, pin 13) overrides the
pushbutton ON. It means, the output can not be switched on
by the button if the pin denes the output state as „off“. This
does not apply, if the control location was set to local. Also
see section 6.9.
• 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 whole interface is galvanically isolated against the
DC output of the device
