1 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.

Issue 10 July 2000 Product Description 2 - 1
2 Product Description
Function In most telecommunications applications, the output of the rectifier
system is electrically connected in parallel with the batteries. The
rectifiers provide boththe power to thetelephone 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 tothetelephone equipment. Thistransition needs no switching
because of the parallel connection of the rectifiers and batteries.
Benefits The J85503C-3, 400-ampere, 60-Hertz rectifier offers you the following
benefits:
• Eliminates internal switching transients typically associated with
older technologies.
• Reduces noise and transients from the commercial ac source. As the
interface between commercial power and telephone equipment, the
ferroresonant rectifier significantly attenuates noise and lightning
surges from commercial lines.
• Introduces far less noise into closely coupled telephone lines due to
lower harmonic components in the input current waveshape.
• Provides highly efficient power conversion.
• Ferroresonant technology and the rectifier's physical design
features combine to provide reliable service, easy maintenance, and
greater cost effectiveness.
• All components in the rectifier meet Lucent Technologies' strict
specifications and reliability standards. The rectifier uses an
extremely efficient, free-convection cooling system that keeps
components operating at temperatures well below the
recommended maximum, resulting in high reliability.

Lucent Technologies Lineage®2000 400A, 60Hz Ferroresonant Rectifier J85503C-3
2 - 2 Product Description Issue 10 July 2000
• All circuits for power control, alarms, voltage regulation, current
limiting, restart, plant interface, and remote monitoring/control are
mounted on replaceable circuit modules. Front access to the circuit
modules simplifies replacement or adjustment, if required.
Standardized modules simplify parts inventory, resulting in lower
costs and better equipment availability.
• The rectifier can be used in a plant with or without batteries and
with or without a controller. The load share feature, equalize
feature, noise filtering, and interface board adapt the rectifier to
practically any application.
Features The J85503C-3, 400 ampere rectifier offers the following standard
features.
Output Current
“Walk-in” This circuit controls the time required for the rectifier to reach its rated output voltage after it is turned on. Initially, the output voltage is about
80 percent of normal, and gradually increases to the required value in
approximately 10 seconds. As the output voltage “walks in,” so does
output current. This feature minimizes the starting surge on the
customer's power source and is especially important with a more limited
power source, such as an engine driven alternator.
Electronic Current
Limit The rectifier provides a constant output voltage up to its rated output current, at which pointitprovides constantcurrent.Thiscurrent limitset
point is adjustable from 30 to 110 percent of the rectifier rating, 120-440
amperes. When the output current tends to increase above the current
limit setting, the current limit circuit overrides the voltage regulating
signal and limits the output current of the rectifier.
Backup Current
Limit In addition to the electronic current limit, the ferroresonant transformers are naturally current limiting to 125-175 percent of full load, or 500-700
amperes.
Selective High
Voltage Shutdown If the battery voltage goes too high, a Lineage®2000 controller signals all of the connected rectifiers. This signal causes the rectifier(s)
delivering morethan10 percent offull load to shutdown. The remaining
rectifiers continue to operate. The J85503C-3, 400 ampere also accepts
a selective high voltage shutdown (HVSD) signal from any external
source via the interface board.
