1.0 INTRODUCTION

This Operating Manual should be read through carefully before installing and operating
the Gravitas X100 Integrated DC Power System.

Connection to this system and servicing it must be performed only by qualified
technicians who are trained in the installation and operation of electrical power
systems. The safety warning described later must be carefully followed.

Unipower Telecom, a division of Unipower Corporation, does not accept responsibility
for safety, reliability or performance of these systems if any modifications or repairs are
carried out by unauthorized personnel. Unipower Telecom specified replacement parts
must be used and must be of the same type and rating to ensure continued protection
against risk of fire.

OPERATING MANUAL

GRAVITAS X100 COMPACT,

INTEGRATED DC POWER SYSTEM

Since Unipower Telecom has a policy of continued product improvement, specifications
and components of this system are subject to change.

2.0 GENERAL DESCRIPTION

2.1 The Gravitas X100 is a compact, integrated DC power system. See Figure

1. It consists of three high power-density, hot-swap rectifier modules
which can produce a total 60 amperes at -48VDC, 99 amperes at +24VDC,
or +12V at 100A depending on system configuration. In a 2+1 redundant
operation the output currents are 40, 66 and 50 amperes, respectively.
There are three standard models of the X100.

2.2 The complete system has a DC distribution panel with up to 5 load cir­cuits which are protected by circuit breakers, GMT fuses or a combination
of the two. Optional is a low-voltage battery disconnect. Battery breakers
for up to two battery strings can be provided.

2.3 The integral controller has LED visual alarms, Form C relay alarms, test
points and set-point adjustments including over- and under-voltage
adjustments. There is a temperature compensation option.

2.4 The complete Gravitas X100 is only 2RU high (3.47 inches or 88.1mm)
and is easily installed by a qualified technician. All connections are at the
rear to DIN-rail terminal blocks. The units may be mounted in 19- or
23-inch racks. See Figure 2.

5.0 RECTIFIER SUMMARY & SPECIFICATIONS

5.1 The Gravitas X100 rectifiers consist of two or three parallel-connected, hot-swap

rectifier modules. There is a choice of three different modules which give the
following maximum system capabilities: -48VDC at 60 amperes, +24VDC at 99
amperes and +12VDC at 100amperes. One rectifier can be used for redundancy
with lower system output.

5.2 The -48, +24 and +12 volt outputs are nominal values. The actual adjustment
ranges are 45 to 58V, 22.5 to 29V, and 11 to 14.5 respectively; the factory-set
outputs are -54.4V, +27.2V, amd 13.6V respectively. Table 5-1 summarizes the
key characteristics of the three rectifier module models.

6.0 POWER DISTRIBUTION SECTION

6.1 Figure 1 shows the top section of the system showing two battery circuit break-

ers (one standard in the 48V model, two standard on the 24 and 12V models).
These battery breakers are rated at 80A each. Next are up to two load breakers
rated 1A to 50A in positions 1 and 2 followed by two additional load breakers
rated at 1A and 20A in postions 3 and 4. An optional 4 (active) position GMT
fuse block rated up to 15A each.

6.2 The total number of DC load circuits is five. This means any combination of up to
five breakers and fuses ar e available.

6.3 The DC distribution connections are made at the rear of the X100 to DIN-Rail
terminal blocks. See Figure 2.
