Introduction
General
Information
This product manual (Select Code 169-790-122) describes the
J85502A-1 25-ampere ferroresonant rectifier. The J85502A-1
rectifier converts commercial 208 or 240 volts ac input power at
60 hertz into highly regulated and filtered, low-noise, 24 or
48-volt dc output power for telecommunications equipment
loads.
Since central offices usually obtain their electrical power from
potentially noisy commercial ac lines (and emergency
generators during commercial power failures), and since high
quality dc power is required in order for the equipment to operate
correctly, the J85502A-1 rectifier is an excellent choice for any
telecommunications battery plant.
The J85502A-1 rectifier can be used with a Lineage

battery plant, older vintage Lucent Technologies battery plants,
or any commercial battery plant. With certain options, it can also
operate off battery.
