1 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
qualitydc power is required inorderforthe 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®2000
battery plant, older vintage Lucent Technologies battery plants,
or any commercialbattery plant. With certain options, it can 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. Each option requires different equipment that Lucent

Lucent Technologies Lineage®2000 25A Ferroresonant Rectifier J85502A-1
2 - 2 Product Description Issue 4 May 1998
Technologies has organized into numbered lists to simplify
ordering.
Ferroresonant
Technology The J85502A-1 rectifier isa member of theLucent Technologies
family of Lineage®2000 ferroresonant rectifiers. Like all the
rectifiersin the family, itrepresents asignificant 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 J85502A-1, 25-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 25A Ferroresonant Rectifier J85502A-1
Issue 4 May 1998 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 must be 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 controller signals
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 in this manual.
•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 shuts down
when this voltage exceeds a preset value. This circuit
operates if the external selective HVSD fails to operate.
This backup HVSD operates from an independent voltage
source per Bellcore standards.
•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.
•Voltage monitor circuit: This circuit monitors the ±5 and
±12 volt dc bias voltage on the control board. This circuit
shuts down the rectifier and issues an RFA alarm when
those voltages fall outside acceptable levels.
•Backup current limit: In addition to the output current
limit, the ferroresonant transformers self-limit current
output between 125-175 percent of full load, or 31.25-43.75
amperes.
•Isolated output current indication: When used with a
Microprocessor Controlled System controller, the rectifier

Lucent Technologies Lineage®2000 25A Ferroresonant Rectifier J85502A-1
2 - 4 Product Description Issue 4 May 1998
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 occurs.
•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.
•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 the straps on the CM1 option board are set for List WA.
See Table 8-B in this manual.
•TR: This signal remotely shuts down the rectifier.
•LOA: The low output alarm signals a controller that the
rectifier input voltage is below the lower limit of the
rectifier operating voltage.
•AC voltage monitor circuit: This circuit monitors the ac
input voltage and shuts the rectifier down if the ac voltage
drops below 170 volts for plants with 208-volt ac input and
195 volts for plants with 240-volt ac input.
Additional
Features Dynamic Response
For any step load change of10 to 90 percent, or 90 to 10 percent,
or a step change of 10 percent of the input voltage, the sense

point voltage remains within 5 percent of its setting, and returns
and remains in the 1/2 percent band within 300 milliseconds.
For batteryless operation, for any step load change of 50 to 90
percent, or 90 to 50 percent, or a step change of 10 percent of the
input voltage, the sense point voltage remains within 10 percent
of its setting, and returns and remains in the 2 percent band
within 500 milliseconds.
Electromagnetic Compatibility
The J85502A-1, 25-ampere rectifier complies with FCC Docket
20780, Part 15,Subpart J as required for Class A applications. In
addition, the rectifier meets all specified operating
characteristics when subjected to electric fields upto 10volts per
meter over a frequency range of 20 to 1000MHz.
Circuit Modules The rectifier's signal processing and control circuitry are located
on replaceable circuit modules or packs. Circuit modules are
plug-in boards that can be ordered separately. Table 8-A lists
recommended spare parts for the rectifier. All circuit modules
areaccessible byopening therectifier door. Figure 5-2 showsthe
location of the circuit modules and other features of the rectifier.
Figures 6-2, 6-3, and 7-1 show the CM1, CM2, and CM3 board
layouts, respectively. A description of each module follows.
• The CM1 circuit module (ED83158-30 Group 2, A)
contains circuitry common to several rectifiers in the
Lineage®2000 rectifier family. The factory provides the
options required for each application by removing certain
wire straps and resistors from the CM1 board. The factory
modification of CM1 is complete when the board is
installed in the rectifier. However, ordered spare or
replacement CM1 boards have not been modified. The
customer must make this modification. See Section 8 for
information on parts to be removed and retained.
• The CM2 circuit module (205A1 control board) contains
the following circuits:
Local power supplies
Feedback regulator
Walk-in feature
Backup high voltage shutdown (BUHVSD)

•TheCM3 circuit module (207A meter board) controls the
digital Output meter on the control panel of List 10
rectifiers. The meter displays the rectifier's output current,
voltage, or the plant battery voltage depending on the
three-position selector switch (see Figure 2-1).
•TheCA1 circuit module (ED83156-30 Group 1) contains a
triac/thyristor snubber network. Refer to schematic drawing
SD82604-01 for further information.
• The CM5 circuit module (434A or B) has ac and dc voltage
monitor circuits. When activated, these circuits shut down
the rectifier. The dc circuit issues an RFA alarm. The
rectifier must be restarted when the problem has been
cleared. When the ac circuit is activated, the rectifier shuts
down but automatically restarts when the corrected ac
voltage is restored.

• The digital output meter is optional on the J85502A-1
rectifier. The meter displays (1) the rectifier output current
when the selector switch is in the AMPS position, (2) the
rectifier output voltage when the selector switch is in the
RECT V position, and (3) the plant battery voltage when
the selector switch is in the BATT V position. The default
display is rectifier output current. Table 2-A gives the
accuracy of this meter in the various positions. The
accuracy of the reading depends on the vintage of the digital
meter board (CM3) in the rectifier. The POWER (control)

switch turns the rectifier on and off. When the switch is in
the Off position, the rectifier cannot be turned on by the
plant controller. When the switch is in the On position, an
MCS controller can remotely turn the rectifier on or off to
satisfy the plant load current requirements. The POWER
ON LED emits a green light to indicate that the rectifier is
on.
• The RFA (Rectifier Failure Alarm)LED lights and a signal
is sent to the plant controller if the rectifier fails because of
external or internal high voltage, a blown +V or -Vfuse, or
an internal unbalance.
• The RECT TEST switch provides a manual test of the
rectifier regulation by simulating a full load (FL) or no load
(NL) condition. Operating the switch raises or lowers the
output voltage setting of the rectifier by 0.25 volt when on
battery. When the switch is in the center position, the
rectifier is in the normal operating state.
• The OUTPUT VOLTS ADJ potentiometer provides for
manual adjustment of the output float voltage.
• The REG test jacks allow for measuring the plant output
voltage at the points where the remote sense leads are
connected. This measurement is accurate only when the
remote sense leads are connected.
• The 1/2 AMP +V and -V alarm fuses protect the internal
voltage sense leads to the rectifier control and regulation
circuits. These fuses are located on the control panel inside
the rectifier door.
• The DC OUTPUT circuit breaker protects the plant from
rectifier malfunction and excessive current, and may be
used to disconnect the rectifier from the battery. An output
circuit breaker alarm issues and the RFA (Rectifier Failure
Alarm) LED lights when the circuit breaker trips.
Alarm and
Control Flow The J85502A-1 25-ampere rectifier is typically installed in a
battery plant that is monitored and controlled by a Lucent
Technologies Lineage®2000 controller. The rectifier generates
various monitoring and alarm signals and, in this type of
installation, sends them to the controller for processing and
subsequent action. The action may be local or remote alarm

Lucent Technologies Lineage®2000 25A Ferroresonant Rectifier J85502A-1
Issue 4 May 1998 Product Description 2 - 9
indications or control signals fed back to the rectifier. Refer to
the various Lineage®2000 controller product manuals for a
description of rectifier signal processing and resultant action.
Figure 2-2 shows the typical signal flow between a rectifier and
a Lucent Technologies controller. The control signals and
alarms enter and leave the rectifier via the CM2 control board.
The Lineage®2000 family of controllers also uses replaceable
circuit modules that give flexibility to battery plant design.
