Product Description
Overview
In most telecommunications applications, the output of the
rectifier system is electrically connected in parallel with the
batteries. The rectifiers provide both the power to the telephone
equipment through the plant distribution and the charging and
float current to the batteries. In the event of commercial power
failure, the batteries supply the required dc power to the
telephone equipment. This transition needs no switching
because of the parallel connection of the rectifiers and batteries.
Ferroresonant
Technology
The J85503A-1 rectifier is a member of the Lucent Technologies
family of Lineage
®
2000 rectifiers. Like all the rectifiers in the
family, 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. This technology provides
excellent output regulation in spite of variations in the incoming
commercial line voltage and frequency, and the outgoing current
or “load.”
Highlights of ferroresonant technology include:
•
Eliminates internal switching transients typically associated
with other technologies.
•
Reduces noise and transients from commercial lines. As the
interface between commercial power and telephone
equipment, the ferroresonant rectifier significantly
attenuates noise and lightning surges from commercial
lines.
