DESCRIPTION
UNIPOWER Telecom's PCM500 Series
Power Control and Monitor System
(PCMS) is a one mounting position high
(1.75 inches) basic control and monitoring
system for DC power plants. It controls up
to 16 rectifiers in up to 4 shelves, precisely
setting the float voltage and equalize
voltage (optional) on all rectifiers
simultaneously. It monitors the battery
voltage and current by means of front
panel test points or optionally by a front
panel digital voltmeter and ammeter.
A front panel yellow LED indicates that the
controller is in the optional equalize voltage
mode. Front panel red LEDs give the following
alarms: rectifier fail alarm-minor, indicating a
single rectifier failure; rectifier fail alarm-major,
indicating two or more rectifier failures; AC input
failure on any rectifier; failure on any fuse or
circuit breaker; failure on one or both low voltage
disconnects; battery overvoltage; and battery
undervoltage. These alarms all have isolated
Form C relay contact outputs.
The PCM500 is available in either 48 or 24VDC
versions and will operate with a positive or
negative polarity plant. It comes with brackets
that permit mounting in either a 19- or 23-inch
relay rack and can be mounted from the front of
the rack with offsets every quarter-inch from
front to back to align with exisitng rack-mounted
equipment. The front panel has voltage adjust-
ment potentiometers for float voltage, equalize
voltage (option), battery overvoltage and
undervoltage, and temperature compensation
set (option). A front panel switch puts the PCMS
in either float or equalize voltage mode. A front
panel green/red LED indicates the controller is
operating or has failed. The PCMS 500 mates
with UNIPOWER Telecom's rectifiers and
shelves.

PCM500 SERIES OPERATING MANUAL This table shows that, for example, a 50mV, 100A shunt is the shunt resis- tance that produces 50mV for a 100A full-scale current. In this case the shunt resistance is 50mV ÷ 100, or 0.5 milliohm. The shunt rating is always the full-scale current that produces 50mV across the shunt. -
