1 Introduction
General
Information This product manual (Select Code 169-790-121) describes the
J85502C-1 125-ampere rectifier. The J85502C-1 rectifier
converts commercial 208 or 240 volts ac input power at 60 Hz
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
qualitydc power is required inorderforthe equipment to operate
correctly, the J85502C-1 rectifier is an excellent choice for any
telecommunications battery plant.
The J85502C-1 rectifier can be used with a Lineage® 2000
battery plant, older vintage Lucent Technologies battery plants,
or any commercialbattery plant. With certain options, itcan also
operate off battery.

2 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.
The rectifier provides alarms and accepts control signals from an
external source. It is Underwriters Laboratory (UL) listed and
Canadian Standards Association (CSA) certified. The rectifier
uses controlled ferroresonant technology, which reduces noise
and transients from commercial lines.
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.
Allcircuitsforpower 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 orwithout a controller. One each of twoinput voltages, two
output voltages, and either negative or positive polarity may be
ordered. Optional noise filtering can be added. Each option

requires different equipment which Lucent Technologies has
organized into numbered lists to simplify ordering.
Ferroresonant
Technology The J85502C-1 rectifier isa 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 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.”
Ferroresonant technology and the rectifier’s physical design
features combine to provide reliable service, easy maintenance,
and greater cost-effectiveness on a dollars-per-output-ampere
basis.
Ferroresonant technology also:
• 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.
• Introduces far less noise into closely coupled telephone
lines due to lower harmonic components in the input current
waveshape compared to other technologies.
• Provides highly efficient power conversion.
Standard
Features The J85502C-1,125-ampere rectifier has 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

Lucent Technologies Lineage®2000 125A Ferroresonant Rectifier J85502C-1
Issue 8 July 1999 Product Description 2 - 3
the starting surge on the customer’s power source and is
especially important with amore limited power source, such
as an emergency generator set.
•Internal selective high voltage shutdown: If the rectifier
voltage goes too high, and it is delivering at least 10 percent
of its rated output current, the rectifier shuts down. If the
rectifier is connected to a Lineage®2000 controller, this
feature is deactivated and the controller furnishes the
external selective high voltage shutdown (HVSD).
•External Selective high voltage shutdown: If the battery
voltage goes too high, the Lineage®2000 controllers signal
all of the connected rectifiers. This signal causes the
rectifier(s) delivering at least 10 percent of rated output
current to shut down. The remaining rectifiers continue
operating. Straps on the CM1 option board must be set for
List WB. See Table 8-B.
•Backup high voltage shutdown: This circuit prevents
damage to the rectifier in the event of high battery voltage.
Each rectifier senses its own output voltage and when this
voltage exceeds a preset value, it shuts down. This circuit
operates if the external selective HVSD fails to operate.
This backup HVSD operates from an independent voltage
source per Bellcore standards.
•Voltage monitor circuit module: This circuit monitors the
± 5 and ± 12 biased dc supply voltages on the 205A1
control board. The circuit shuts down the rectifier and issues
an RFA alarm when these voltages fall below acceptable
levels.
•Output current limit: The rectifier provides a constant
output voltage up to its rated output current, at which point
it provides constant current. When the output current tends
to increase above the rated output, the current limit circuit
overrides the voltage regulating signal and limits the output
current of the rectifier.
•Back-up current limit: In addition to the output current
limit, the ferroresonant transformers self-limit current
output between 125-175 percent of full load, or 156-219
amperes.

Lucent Technologies Lineage®2000 125A Ferroresonant Rectifier J85502C-1
2 - 4 Product Description Issue 8 July 1999
•Isolated output current indication: When used with a
Microprocessor Controlled System controller, the rectifier
provides an isolated 2- to 10-volt signal, corresponding to a
range of no-load to 125 percent of rated output load, which
is used to indicate the rectifier drain on the controller.
•Safety interlocks: A series-loop circuit electrically
interconnects the control circuit modules and prevents
rectifier operation if an open circuit is detected.
•Fuse alarm circuit: The low-power control functions shut
the rectifier down if a fuse alarm (FA) occurs. One fuse
alarm protects each of the regulation leads. When any FA
occurs, a Rectifier Failure Alarm (RFA) LED lights on the
front panel and an RFA signal is generated. The FA LED
also lights.
•Man alarm: This alarm indicates that either the rectifier
has been turned off manually or has lost commercial input
power.
•Restart circuit: The rectifier has an automatic restart
feature that is compatible with the Lineage®2000
controllers and most other controllers. If a rectifier shuts
down due to the external selective HVSD, most controllers
try at least once to restart it automatically.
•Remote sense leads: These leads permit remote regulation
of the rectifier if it is installed with a compatible controller
and straps on CM1 option board are set for List WA. See
Table 8-B.
•TR: This signal remotely shuts down the rectifier.
•AC voltage monitor circuit: This circuit monitors the ac
input voltage and shuts the rectifier down if the ac goes
below the following voltages:
Input Low
208 170
240 195
•LOA: The limited output alarm (LOA) signals a controller
that the rectifier has lost input voltage.
