Introduction
J85503C-3
This product manual (Select Code 169-790-132) describes the
J85503C-3, 3-phase, 400-ampere, 60-Hertz, -48-volt, floor-mounted
rectifier.
The J85503C-3 rectifier is a member of the Lucent Technologies family
of Lineage
®
2000 rectifiers. Like all Lineage
®
2000 rectifiers, it
represents a significant advancement in efficiency, space savings, and
serviceability. The rectifier uses the electronically controlled,
closed-loop, ferroresonant technology developed by Lucent
Technologies Bell Laboratories. This technology provides excellent
output regulation in spite of variations in the incoming commercial line
voltage and frequency, and the outgoing current or load.
The J85503C-3 rectifier converts commercial 416-volt ac input power
at 60 Hertz into highly regulated and filtered, low-noise, -48-volt dc
output power for telecommunications equipment loads. Central offices
usually obtain electrical power from potentially noisy commercial ac
lines and/or emergency generators during commercial power failures.
The J85503C-3 rectifier provides the high quality dc power required for
proper operation of telecommunications equipment.
Lucent Technologies developed the J85503C-3 rectifier to support large
central office applications where high reliability, low maintenance, long
life, and fault tolerance are critical.
The J85503C-3 rectifier can be used with a Lineage
®
2000 battery plant
or any commercial battery plant. It can boost charge batteries and
equalize batteries off-line to 65 volts as well as operate without
batteries. The rectifier works with Lucent Technologies controllers to
provide control and alarm functions. An interface board is available to
access these functions with commercial controllers.
