1 Introduction
Description of
Product ThisLucent Technologiesproductmanual (167-790-125)covers
product features and specifications, converter technology,
installation and testing, as well as operation and maintenance.
This manual describes the Flexible Power System 693AA
DC/DC Converter which transforms 24-volt dc source voltages
into highly regulated, low noise, -50-volt, 10-ampere dc power
sources for usewith telecommunicationsloads.This converteris
used in the Lineage®2000 Flexible Power System (FPS)
DC/DC converter plant.
When used in the Lineage®2000 FPS DC/DC converter plant,
the power system can serve power needs within the 10 to 120
ampere range. To achieve this current range, the system grows
in capacity from a one-shelf plant, which accepts up to six
converters, into a two-shelf plant capable of housing 12
converters.
Included in the shelf assemblies is a sophisticated plant monitor
and control panel, facilities to terminate the input distribution,
and output distribution and protection panels. The monitor and
control panel serves both one- and two-shelf plants. Input
termination and output distribution/protection facilities are
provided with each shelf. Figure 1-1 shows a 693AA DC/DC
Converter. Figure 1-2 illustrates one and two shelf DC/DC
Converter or Rectifier/Converter plants.
The Lineage®2000 FPS series converters are designed
specifically for applications where size, weight, ease of
installation and maintenance are of overriding importance.

Lucent Technologies Lineage®2000 693AA DC/DC Converter
1 - 2 Introduction Issue 2 September 1996
When plugged into a converter plant shelf assembly as shown in
Figure 1-2, all interconnections between the converter, the
monitor and control panel and the input and output distributions
are completed. This front access, plug-in design plant permits
growth and easy maintenance without interrupting service.
Because the DC/DC converter plants are physically
interchangeable with Lineage®2000 ECS battery plant rectifier
shelves, these converter plants may be used with ECS battery
plants to provide fully integrated systems where dual voltage,
battery backed power is needed.
These features make the FPS series converters the ideal choice
for power applications in the 10 to 120 ampere range. UL
recognized and CSA certified, these FPS series converters can
be operated with or without the monitor and control panel,
providing the user with maximum flexibility.
Technology
Highlights The Lucent Technologies family of Lineage®2000 FPS series
converters represents a significant advancement in space
utilization and ease of installation over previously available
products.A unique Bell Laboratories design, which incorporates
100 kHz switching frequency, advanced technology, and
forced-air cooling, has resulted in converters which occupy
minimal space. This 10-pound switchmode converter design
provides excellent output regulation over a wide range of load
currents, and input voltages. Processing the power at higher
frequencies allows for substantial reduction in the size and
weight of the energy storage elements.
The SR series converters use forced-air cooling to help achieve
high power density and light weight. Each unit is equipped with
easily replaceable, self-contained cooling fans (see Section 6).
Thermal alarm circuitry offers additional protection by shutting
down the converter and providing an alarm when the internal
temperature exceeds approximately 70°C. Forced air cooling
improves the reliability of the converter by reducing the internal
ambient temperatures of the converter to essentially the outside
ambient temperature.
FPS series converters feature automatic load-share circuits
which force the converters to equally share the plant load, thus
reducing the stress on individual converters. FPS series
converters are self protected; short circuits and system overloads

Lucent Technologies Lineage®2000 693AA DC/DC Converter
Issue 2 September 1996 Introduction 1 - 3
are handled automatically, if the short circuit is removed, or the
system load reduced, the converters automatically resume
normal operation.
Signalinterfacesbetweenthe FPS seriesconverters andthe plant
monitor and control panel provide alarm monitoring, converter
output voltage adjustment, plant current monitoring, lamp test,
and converter on/stand by control.
These features allow Lucent Technologies to offeraswitchmode
converter product and associated power plants that meet the
same standards for system flexibility and reliability found in our
ECS power plants equipped with SR series rectifiers.

Lucent Technologies Lineage®2000 693AA DC/DC Converter
2 - 4 Product Description Issue 2 September 1996
Parallel operation The converters are capable of operating in parallel with
other 693AA DC/DC Converters.
Load share A load share circuit automatically forces the converters to
share the plant load. The load share circuit is made fail-safe
by using an isolated load share bus between the converters.
Upon failure, the failed converter is disconnected from the
load share bus.
Active inrush current
limiting Upon application of the dc source voltage, an active circuit limits the peak inrush current, thus eliminating nuisance
tripping of customer provided input breakers.
Output current limit The converter provides a constant output voltage up to its
rated output current, at which point it begins to provide
constant current. The maximum output current is limited to
less than 125% of the rated output and no user adjustment
is necessary.
Internal selective
high-voltage shutdown If the converter plant voltage goes too high, only the defective converter or converters will shut down.
Restart circuit If a converter has been shut down due to high voltage, it
will try to restart a maximum of three times automatically.
After three unsuccessful tries, the converter shuts down
and locks down.
Converter alarm The converter alarm provides both a local visual indication
of low output voltage and a signal to the plant monitor and
control panel. An CFA is generated by the following
output undervoltage, thermal alarm, and/or an operated
internal fuse.
Thermal alarm The FPS series converters are fan cooled to increase their
reliability. Excess internal temperatures caused by fan
failure or other conditions initiate a thermal alarm. See
Section 6 - Maintenance for details on fan replacement.

Additional
Information
Dynamic response Step changes in load over the range of 10 to 90 percent, or 90 to
10 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.
Lightning protection The converters are capable of withstanding without damage
repeated surges of the following waveforms (per IEEE
C62.41-1991 and IEEE 587-1980 requirements):
• Rise time of 8 microseconds to 3000 amperes peak amplitude
and decay time to 1500 amperes in 20 microseconds.
• 0.5 microsecond - 100 kHz ring wave with a peak voltage of
6000 volts.
Shipping The converter in its shipping container will withstand the
vibrations and shocks normally encountered in shipping without
damage or degradation of performance.

details. When not shipped assembled in a plant frame, the FPS
power plants are shipped with all mounting hardware necessary
for assembly to standard frames.
Additions to
Existing Plants When adding converters to existing power plants, consideration
must be given to converter loads and the availability of both dc
source power and protection for load feeder circuits.

Lucent Technologies Lineage®2000 693AA DC/DC Converter
3 - 2 Engineering Information Issue 2 September 1996
Although the converters and FPS power plants are keyed to
prevent accidental insertion of converters having input or output
voltages that differ from the plant voltage, care should be
exercised to avoid using excess force to seat a converter in a
plant.
Heat Dissipated
to Environment The maximum heat load imposed on the environment by a
converter is provided in Table 2-A in Section 2. The 693AA
DC/DC Converters are designed for forced air cooling: the
building or area must have a maximum ambient temperature no
greater that 50°.
Warning
Converters and rectifiers in the Flexible Power System
product family appear similar and may be identified only by
the label.
