1 Introduction
60-volt Cabinet
Power System The low-maintenance, outside-plant 60-volt/60 Hz CPS
integrates advanced technology in a modular system. The
system delivers highly regulated, low-noise power over a wide
range of load currents and input voltages. Using switchmode
technology to process the power, along with forced-air cooling
in the rectifiers, results in a power unit characterized by high
power density, light weight, and an extended service life.
Applications Lucent Technologies has developed the 60-volt, 60-Hertz Small
Broadband Power System to support the growing needs of
broadband video/telephony networks.
Configurations The single-shelf Cabinet Power System (CPS) houses one
rectifier and a Battery Polarity Switch (BPS). The rectifier uses
commercial ac power to produce 82 volts dc. The BPS converts
the 82-volt dc power to a nominal 60-volt ac @ 60 Hz output for
powering the broadband network.
In a fully configured system, the CPS shelf contains one (1)
ES664 rectifier and one (1) ES635 Battery Polarity Switch. In
addition to converting the rectifier output, the BPS provides the
alarm and control functions as well as the output distribution
circuit breakers and connectors.

2 Product Description
Overview Figure 2-1 is a block diagram of a 60-volt/60 Hz CPS battery
plant. The shelf assembly houses and interconnects the ES664
rectifier andthe ES635 Battery Polarity Switch(BPS). The shelf
design provides a platform which accepts plug-in modules,
thereby simplifying plant assembly and repair. Furthermore, this
plug-in design permits growth of plant capacity as well as easy
maintenance without interruption of service. Keying prevents
improper insertion of incompatible modules.
Power Modules These units have been designed specifically for applications
where size, weight, ease of installation and maintenance are
important. Switchmode circuit design provides excellent output
regulation over a wide range of load currents and input voltages.
Power processing at higher frequencies allows for substantial
reduction in the size and weight of energy storage elements.
Higher frequencies and the use of forced-air cooling in the
rectifier help achieve high power density and light weight. The
ES635 (BPS) is convection cooled.

2 - 2 Product Description Issue 4 October 1998
The rectifier is equipped with field replaceable, self-contained
cooling fans. Thermal alarm circuitry offers additional
protection by shutting the power unit down and providing an
alarm when the internal temperature exceeds 75° C. Forced air
cooling improves the reliability of power units by maintaining
their internal temperatures very close to the outside ambient
temperature.
60-volt/60 Hz CPS series power units are self-protected such
that short circuits and system overloads are handled
automatically; i.e., if a short circuit is removed or a system
overload reduced, the power units will automatically resume
normal operation.
Signal interfaces between the 60-volt/60 Hz CPS rectifier and
the plant control unit provide alarm monitoring, rectifier output
voltage adjustment, lamp test, and rectifier On/Standby control.
For inverters, the signal interface with the control unit provides
alarm monitoring and lamp test, but does not allow voltage
adjustment or current monitoring.
Features The following list describes standard features for 60-volt CPS
series power modules.

Issue 4 October 1998 Product Description 2 - 3
•Light weight, easy to install: These connectorized,
pluggable units may be installed in 60-volt CPS power
plants in less than one minute.
•Simplified plant administration: Rectifiers may be
installed in a working plant without adjustment and without
interruption of service. System failures can be easily
corrected by replacing defective power modules. Defective
fans may be easily replaced in the field.
•Front access only: Power modules and the 60-volt CPS
power plants may be installed and serviced without the need
for rear access.
•User friendly: Front panel LED indicators on power
modules as well as the control unit front panel indicate
system status.
•Lamp test: A push-to-test switch on the plant Alarm
Control Unit activates all plant alarm and status LED
indicators.
•Active inrush current limiting: Upon application of the
source voltage, an active circuit limits the peak inrush
current, thus eliminating nuisance tripping of customer
provided input breakers.
•Output current limit: Power modules provide a constant
output voltage up to their rated output current, at which
point they begin to provide constant current outputs. The
maximum output current is inherently limited to less than
110% of the rated output without user adjustment.
•Internal selective high-voltage shutdown: If the plant
voltage goes too high, only the defective power module will
shut down.
•Restart circuit: If a rectifier or inverter has shut down due
to high voltage, it will try to restart a maximum of two times
automatically. After two unsuccessful tries, the power
module shuts down and locks down.
•Power module alarm: The power module alarm provides
both a local visual indication of low output voltage as well
as a signal to the plant control unit. In addition, alarms are
generated by either a high module temperature and/or an
operated internal fuse.

2 - 4 Product Description Issue 4 October 1998
•Thermal alarm: The rectifiers are fan cooled to increase
their reliability. Excess internal temperature caused by fan
failure or other conditions initiates a thermal alarm.
•Power factor: State-of-the-art circuits in the rectifiers
increase the power factor to near unity.
•Total harmonic distortion: By controlling the power
factor, the total harmonic distortion is reduced to less than
five percent at full load.
•Voltage range selection: CPS power modules
automatically accept a wide range of ac input voltages.
•Dynamic response: Step changes in load over the range of
10 to 90 percent, will not cause the voltage measured at the
point of regulation to overshoot or undershoot more than 5
percent. After the step change, the voltage will return to and
stay within the regulation band within 300 milliseconds.
• CPS power modules are capable of withstanding repeated
surges of the following wave forms (per ANSI C62.41-1991
requirements) without damage:
– Rise time of 8 microseconds to 3000 amperes peak
amplitude and decay to 1500 amperes in 20
microseconds.
–0.5 microsecond-100 kHz ring wave with a peak voltage
of 6000 volts.
Inverter (BPS) Each BPS inverter, ES635, provides four outputs, with each
delivering 110 Watts of power. The BPS output is 60 volts
polarity-switched at 60 Hz.
The ES635 BPS is a double-wide unit that houses the Alarm
Control Unit (EBM1) and distribution circuit breakers for the
four outputs.
Alarm Control
Unit An Alarm Control Unit (ACU) is included in the 60-volt/60 Hz
system. The ACU (EBM1) provides plant monitoring and
control features as well as office alarm outputs.
Alarm reporting for the 60-volt/60 Hz CPS plants is typical of
telecommunication battery plants. Alarms are categorized as
