About the device
2.5 Analog interface connection
The 12 pole analog interface on the right side is
of type press & clamp. It is eligible for cable cross
sections of 0.1mm² (26 AWG) to 0.5mm² (20 AWG).
If possible, use cable end sleeves.
Attention! Never connect grounds of the ana-
log interface to minus (negative) output of an
external control application (PLC etc.), if that
control application is already connected to the
negative power supply output (ground loop).
Load current may flow over the control leads
and damage the device! In order to avoid this
a fuse can be integrated in the „weak“ ground
line.
Clamping procedure:
3. Functional description
3.1 Remote sense
In order to compensate voltage drops along the load
leads, the device features remote sense inputs on
the front. Here the sensed voltage from the load is
connected with correct polarity. Remote sense can
compensate up to a certain level, see „4. Technical
, item „Remote sense compensation“
for details.
When not using the sense inputs, they just remain
open. It is not required to bridge them to the output.
The cross section of the sense leads is non-critical.
3.2 Share Bus
The Share-Bus connector at models of series PS
800 R is without function.
3.3 Overvoltage protection (OVP)
All models feature an overvoltage protection circuit
which follows the currently adjusted voltage set
value with an offset. This offset is:
80V models: 3V, 360V model: 14V
If, for example, a 360V model is set to 200V, then
the OVP would act at around 214V.
In case of an overvoltage condition, whether caused
by an internal defect or by external reasons, the po-
wer output is switched off and the error is indicated
by the LED „OVP“ and also by pin 9 of the analog
interface. After the OV condition is gone, the output
can be switched on again.
3.4 Overtemperature (OT)
All models also feature an internal temperature
supervision. In case of overheating, the power out-
put will be temporarily switched off until the device
has cooled down, and then automatically switch on
again.
The condition is indicated by the LED „OT“ and by
pin 9 (OT/OVP) of the analog interface.
3.5 Analog interface
All models feature a 12 pin analog interface on the
front of the device. It can be used to monitor the de-
vice condition, as well as remotely switch the output
on or off. Also see section „5.5 Remote control“.
3.6 Power reduction
Models with 1500W nominal power will switch to a
power reduction of 1000W at mains input voltage
of 150V and under. Permanent operation at grids of
115V nominal voltage, like for example in the USA,
will always result in max. 1000W output power.
