Lucent Technologies 60V Small Broadband Power System J85500Q-1
2 - 2 Product Description
Issue 4 October 1998
The rectifier is equipped with field replaceable, self-contained
cooling fans. Thermal alarm circuitry offers additional
protection by shutting the power unit down and providing an
alarm when the internal temperature exceeds 75° C. Forced air
cooling improves the reliability of power units by maintaining
their internal temperatures very close to the outside ambient
temperature.
60-volt/60 Hz CPS series power units are self-protected such
that short circuits and system overloads are handled
automatically; i.e., if a short circuit is removed or a system
overload reduced, the power units will automatically resume
normal operation.
Signal interfaces between the 60-volt/60 Hz CPS rectifier and
the plant control unit provide alarm monitoring, rectifier output
voltage adjustment, lamp test, and rectifier On/Standby control.
For inverters, the signal interface with the control unit provides
alarm monitoring and lamp test, but does not allow voltage
adjustment or current monitoring.
