About the device
General
Introduction
The microprocessor controlled power supplies of the
PS 800 R series are designed for wall mount and are
cooled by a temperature-controlled fan.
The functionality focuses industrial power supply. It
means, the device will continue its work with the last
settings after a blackout.
The output voltage is seperated into three selectable
ranges, where each one is defined as approximately
1/ of the nominal voltage.
The power output is short-circuit-proof and over-
load-proof. For protection of the loads, the devices
also feature an overvoltage protection (OVP). At an
overtemperature (OT) event, the power output will
be switched off until the unit has cooled down and
automatically switch on again.
Models with 1500W output power will switch to a
1000W output power limitation at mains input voltages
of <150V
AC

Visual check
After receipt, the unit has to be checked for signs
of physical damage. If any damage is found, the
unit may not be operated. Also contact your dealer
immediately.

Installation
Mounting
The device is designed for wall mount. It is required
to mount it in a way that allows unimpeded air flow
through the ventilation slots. Take care for plenty of
space (at least 15cm) below and above the device in
order to ensure proper cooling. The included mounting
kit contains strips that can be attached to the device in
vertical or horizontal position. These strips have drill
holes for screws with up to 5mm thread.
Also see drawing on page 14.
Mains connection
All models are equipped with an active PFC (power
factor correction) and a wide range input. It can be
operated at AC input voltages from 90V to 264V and
mains frequencies of 45Hz up to 65Hz.
The connection is done at the pole terminal „Power
Input“ on the front plate. It must only be carried out
by trained technical personnel. Main focus lies on
an appropriate cross section of the mains lead, as
well as the fact that the device does not feature a
power switch. The mains input is fused by a standard
5x20mm fuse, type T16A, which is located in the fuse
holder on the front plate.
DC output connection
The load is connected to the DC output terminals on
the front using leads with appropriate cross section.
The device can produce dangerous voltages. Thus
the output must be covered when working with the
device. The included shrinking hose can be used, or
something similiar.
Functional description
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 2V.
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.
Overvoltage protection (OVP)
All models feature an overvoltage protection circuit
which is set 110% of the nominal output voltage. In
case of an overvoltage condition, whether caused by
an internal defect or by external reasons, the power
output is switched off and the error is indicated by
the LED „OVP“ and also by pin 10 of the analogue
interface. After the OV condition is gone, the output
can be switched on again.
Overtemperature (OT)
All models also feature an internal temperature super-
vision. In case of overheating, the power output 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
10 of the analogue interface.
