Lucent Technologies 60V Small Broadband Power System J85500Q-1
Issue 4 October 1998
Product Description 2 - 3
•
Light weight, easy to install: These connectorized,
pluggable units may be installed in 60-volt CPS power
plants in less than one minute.
•
Simplified plant administration: Rectifiers may be
installed in a working plant without adjustment and without
interruption of service. System failures can be easily
corrected by replacing defective power modules. Defective
fans may be easily replaced in the field.
•
Front access only: Power modules and the 60-volt CPS
power plants may be installed and serviced without the need
for rear access.
•
User friendly: Front panel LED indicators on power
modules as well as the control unit front panel indicate
system status.
•
Lamp test: A push-to-test switch on the plant Alarm
Control Unit activates all plant alarm and status LED
indicators.
•
Active inrush current limiting: Upon application of the
source voltage, an active circuit limits the peak inrush
current, thus eliminating nuisance tripping of customer
provided input breakers.
•
Output current limit: Power modules provide a constant
output voltage up to their rated output current, at which
point they begin to provide constant current outputs. The
maximum output current is inherently limited to less than
110% of the rated output without user adjustment.
•
Internal selective high-voltage shutdown: If the plant
voltage goes too high, only the defective power module will
shut down.
•
Restart circuit: If a rectifier or inverter has shut down due
to high voltage, it will try to restart a maximum of two times
automatically. After two unsuccessful tries, the power
module shuts down and locks down.
•
Power module alarm: The power module alarm provides
both a local visual indication of low output voltage as well
as a signal to the plant control unit. In addition, alarms are
generated by either a high module temperature and/or an
operated internal fuse.
