About the device
2.4 Analogue interface connection
The 12 pole analogue interface on the front 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-
logue 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 avo-
id this a fuse can be integrated in the „weak“
ground line.
Clamping procedure:
2.5 Remote sense connection
The remote sense inputs are located on the top of
the device. If remote sense is going to be used, the
connection is easily done using the included Phoenix
plug on connector „Sense“.
3. Functional description
3.1 Remote sense
In order to compensate voltage drops along the load
leads, the device features remote a sense input on
the top side. Here the sensed voltage from the load
is connected with correct polarity. See „4. Technical
specifications“ about how much voltage drop remote
sense can compensate.
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 Overvoltage protection (OVP)
All models feature an overvoltage protection circuit
which follows the adjusted voltage set value with an
offset. This offset is:
80V model: 7V
200V model: 17V
500V model: 42V
If, for example, the 500V model is set to 200V, then
the OVP would act at around 217V.
Because the offset is not adjustable, the user has to
consider possible voltage incrementals coming from
the power supply before the OVP reacts.
In case of an overvoltage condition, whether caused
by an internal defect or by external reasons (mutual
induction), the power output is switched off and the
error is indicated by the LED „OVP“ and also by pin
9 of the analogue interface. After the OV condition
is gone, the output can be switched on again.
The same applies for remote control via the analo-
gue interface.
3.3 Overtemperature (OT)
All models also feature an internal temperature su-
pervision. In case of overheating, the power output
will be temporarily switched off until the device has
cooled down, and then automatically switched on
again.
The condition is indicated by the LED „OT“ and by
pin 9 (OT/OVP) of the analogue interface.
3.4 Analogue interface
All models feature a 12 pin analogue interface on
the front of the device. It can be used to monitor
the device condition, as well as remotely switch the
output on or off and, of course, to remotely control
the device. Also see section „6. Remote control“.
3.5 Current limitation
The output current of the device is not adjustable
and thus limited to the nominal output current. It
always has to be considered that in case of a very
small load or short-circuit at the output the device
will constantly deliver the maximum current. This
can damage the connected load.
3.6 Flexible power limitation
The device has a maximum output power of 5000W
which is limited by a flexible output stage. It means, it
can provide either high voltage with comparably low
current or high current with comparably low voltage.
In either case, the power is limited according to the
formula P = U * I.
3.7 Share bus connection
The Share-Bus connector at models of series PS
800 R is without function.
