1 Introduction
General This product manual describes the J85503B-2, 3-phase,
200-ampere, 60-hertz, -48 and ±24 volt, floor-mounted
ferroresonant rectifier. The manual covers rectifier technology,
features and specifications, installation and testing, and
operation and maintenance.
The J85503B-2 rectifier is a member of theLucent 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 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 J85503B-2 rectifier converts commercial 208/240/480-volt
ac input power at 60 hertz into highly regulated and filtered,
low-noise, -48 and ±24 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 J85503B-2 rectifier provides the high quality dc
power required for proper operation of telecommunications
equipment.
Applications Lucent developed the J85503B-2 rectifier to support large
central office applications where high reliability, low
maintenance, long life, and fault tolerance are critical.

Lucent Technologies Lineage®2000 200A Ferroresonant Rectifier J85503B-2
1 - 2 Introduction Issue 8 January 1999
Features The J85503B-2 rectifier can be used with a Lineage®2000
batteryplant oranycommercialbatteryplant.Itcanboostcharge
batteries and equalize batteries off-line to 65 volts (for -48-volt
plants) or to ±32 volts (for ±24 volt plants), 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.
Benefits The J85503B-2 rectifier offers you the following:
• 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.
High reliability: 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, which results in high
reliability.
Easier maintenance: 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.
Wide versatility: The rectifier can be used in a plant with or
withoutbatteries and with or without a controller. The loadshare

2 Product Description
General 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.
Typical Battery
Plant Figure 2-1 shows a basic block diagram of a typical dc battery
plant. The battery plant accepts alternating current from the
commercial utility or a standby ac power source and rectifies it
toproduce dc power for the using equipment.The plant’s control
and alarm functions interact with the rectifiers and the office. In
addition, the plant provides overcurrent protection, charge,
discharge, and distribution facilities. Battery reserve
automatically provides a source of dc power if the commercial
or standby ac fails. This battery reserve is engineered to supply
dc powerfor a specific periodof time. In normalpractice, battery
capacity is sized to provide 3 to 8 hours of reserve time.
Battery Plant
Subsystems AC Input: connects the commercial and/or standby ac power
sources to the rectifiers within the plant and provides
overcurrent protection. This subsystem is usually supplied by
the customer.
Rectifiers: convert an ac source voltageinto the dc voltagelevel
required to charge and float the batteries and to power the using
equipment.

2 - 2 Product Description Issue 8 January 1999
Controller: provides the local and remote control, monitor and
diagnostic functions required to administer the battery plant.
Batteries: provide energy storage for an uninterrupted power
feed to the using equipment during loss of ac input or rectifier
failure.
DC Distribution: provides overcurrent protection, connection
points forthe using equipment,and bus barsused to interconnect
the rectifiers, batteries, plant shunt, and dc distribution.
Converters: transform -48 volt source voltages into regulated,
low-noise 24 volt dc power sources for use with
telecommunications loads.
Features The J85503B-2 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 80percent 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 thestarting surgeon thecustomer’spower source and
is especially important with a more limited power source, such
as an engine driven alternator.
