PS 800 R Series
6.1.3 Adjust set values 1
Analogue inputs: VSEL(1) and CSEL(2)
This example shows how the set values can be
adjusted using the reference voltage (10V, VREF)
and potentiometers on the set value inputs.
The bridge between pin 10 and Pin 7 switches the
device to the required remote control mode. This
bridge can be substituted by a low resistive switch.
In case only one of both set values shall be adjusted,
the other one should be tied to pin VREF.
The potentiometer should be 10kΩ each or higher.
6.1.4 Adjust set values 2
Analogue inputs: VSEL(1) and CSEL(2)
The example shows how to control voltage and
current by means of external voltage sources. Also
see example 1.
Attention! Never connect voltages >12V to these
inputs!
Set values >10V are internally clipped to 100%
nominal value.Other applications
7. Other applications
7.1 Series connection
It is possible to connect multiple units of preferrably
the same type to a series connection if these rules
are followed:
• No master-slave operation
• The grounds of the analogue interfaces MUST
NOT be connected to each other. This also applies
for any other signal on the analogue interfaces. If
remote control is required, it can be done using
galvanic isolation amplifiers and by controlling on
or all units in parallel.
• The remote sense terminal must not be wired!
• The Share Bus terminal must not be wired!
• No negative DC output pole of any device may
have a potential >300V against earth (PE).
7.2 Parallel connection
The parallel connection and operation of multiple
identical units is basically possible, but not explici-
tely supported. Due to the overvoltage protection
level that follows the adjusted output voltage, it is
not possible to use the analog interface to create a
master-slave-like system or to use the Share Bus
for load current distribution.
