DESCRIPTION
Gravitas X150 is a compact, integrated, DC power system. It
consists of up to three high power-density, hot-swap rectifier
modules which can produce 75 amperes at -48VDC, 150 amperes
at -48VDC or 150 amperes at +24VDC, depending on system
configuration. In a 2+1 redundant operation the output currents
are 50, 100 and 100 amperes, respectively.
The system has a DC distribution panel with up to 10 load
circuits which are protected by circuit breakers, GMT fuses or a
combination of the two. Three Also optional is a low-voltage
battery disconnect. Battery breakers for up to three battery
strings can be provided.
There are two choices for the system controller. A basic controller
has LED visual alarms, Form C relay alarms, test points and setpoint adjustments including over- and under-voltage adjustments. There is a temperature compensation option and digital
voltage and current display option. An optional intelligent
controller provides all these features in keyboard format with an
alphanumeric display and remote data access options.
The complete Gravitas X150 is only 5RU high (8.65 inches or
220mm) and is easily installed by a qualified technician. All
connections are at the rear to DIN-rail terminal blocks. A
comprehensive operating manual explains all the details of
operation and installation. The units may be mounted in 19- or
23-inch racks.

BASIC CONTROLLER (Standard)
INTELLIGENT CONTROLLER (Option)
This basic controller controls the system rectifier,
monitors the system parameters and has alarms for
system failures. There are seven red LED alarms which
also have Form C relay outputs to indicate a failure:
Rectifier-Major, Rectifier-Minor, AC Input, Fuse or
Circuit Breaker, Low Voltage Disconnect, Overvoltage
and Undervoltage. Four front-panel voltage-set
adjustments are for Float Voltage, Battery Overvoltage, Battery Undervoltage and Temperature Compensation. Test points for load voltage and current
permit external measurement of these values. Options
for this controller include digital meters for continuously monitoring battery voltage and load current
and a temperature probe which provides a temperature compensated output from the rectifier.
This full-featured controller is a control and supervisory unit that communicates directly with the
rectifier to monitor and control its function. The
digital controller features a keypad and a back-lit
2x24 character alphanumeric display. All system
parameters can be controlled by the keypad. Alternatively, the system can be controlled by software from
a remote PC by means of a standard RS232 port or
via an optional modem or Ethernet LAN. This
controller also has an optional temperature probe for
temperature compensated output from the rectifier.
