INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
The PSR-5H is a plug-in power supply unit for the AFI SR-50H redundant power supply sub-
rack frame. Redundancy is provided by utilizing two PSR-5H power supplies which operate in
an “active (hot) standby” configuration. The PSR-5H power supplies plug into the two power
supply positions on the sub-rack which are on the right side of the unit. Each of the PSR-5H
units are 100W regulated high efficiency power supplies.
These two power supplies connect to the sub rack backplane in an “either or” configuration
which means that one or both may be providing power to the sub rack simultaneously.
However, when both are providing power, the current requirement from each supply is reduced
proportionally. If both supplies are providing power equally to the sub rack load, each will then
be operating at only 50% of its total power capacity.
Typically the power supplies are not perfectly balanced and one or the other of the PSR-5H
power supplies are providing most or all of the sub rack power requirements. If either one of the
PSR-5H power supplies fails, loses input power, or is switched (turned) off, power is seamlessly
maintained to the sub rack by the second unit. When the non operating power supply is
replaced or switched back on, both the PSR-5H power supplies are automatically available to
provide sub rack power. No reset is required.
Utilizing state of the art, low noise, switching power supply technology, each PSR-5H power
supply provides up to 100 Watts of output power to be provided to the application cards. Over
voltage and thermal protection are included in each unit. There are no user serviceable parts
inside. Up to eleven single or five dual position plug in cards can be powered by each of the
PSR-5H power supplies.

INSTALLATION
This installation should be made by a qualified service person and should conform to all local
codes. All wiring methods should be in accordance with the National Electric Code, ANSI/NFPA
70. The unit slides in and is locked into place by four ¼ turn fasteners. The line cord is then
plugged in from the rear. Please note that this supply is intended to be used with, and only
when inserted into, an SR-50R sub-rack frame. Be sure that the power switch is in the off
(rocker switch in upper position) before connecting to the power source. The rear of the unit
includes an exhaust fan. In order to insure long life and reliable operation, air-flow from the fan
port should not be obstructed. The sub-rack SR-50R is supplied with two three-conductor power
cords. The “ground conductor” is directly connected to the chassis
LINE VOLTAGE
For proper operation, the input line voltage should be in the range of 100 to 240 VAC, 50 - 60
Hz, properly grounded and conforming to all local codes. A universal power connector is
provided on the rear of the unit to facilitate connection to the power mains.
POWER INDICATOR
A front panel LED indicates the AC line (POWER) being present and the power switch being in
the on position. The ON/OFF switch is located on the rear of the unit.
