About the device
General
Introduction
The microprocessor controlled power supplies of the
PSI 800 R series are designed for wall mount and
work with a convectional cooling.
The functionality focuses industrial power supply. It
means, the device will continue its work with the last
settings after a blackout.
All models feature fixed voltage ranges, as well a full
voltage range. The fixed voltage ranges are configu-
rable within certain limits, the full voltage range is not
limited and offers 100% of all nominal values.
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.
The devices are equipped with an analogue interface
and an extension card slot by default, that enables
remote control and monitoring by digital interfaces
like USB, RS232 or CAN.
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 ow
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 12.
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 with the included 3pole plug
(Phoenix Combicon GMSTB 2,5/3-ST-7,62) according
to the print 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 which is located inside the unit.
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
General
The power supply is pre-congured to a certain vol-
tage and current.
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.
