1.0 INTRODUCTION
Gravitas X75 is an ultra-compact, integrated DC power system. The base system is a 1RU
shelf holding up to three hot-swap rectier modules. This system produces up to 1950 watts
output at -54.4, +27.2 or +13.6VDC. It can also be operated as a 2+1 redundant system with
up to 1300 watts output. The expanded system consists of a base shelf plus an expander
shelf with a 2RU total height. This system holds up to six rectier modules with up to 3900
watts output; it can be operated as a 5+1 redundant system with up to 3250 watts output.
Each rectier module is cooled by a fan that operates at a speed which is a function of load
and temperature.
There are up to ve circuit-breaker protected DC outputs or up to 10 GMT fuse protected
outputs on the base system. A battery string breaker and a low-voltage battery disconnect
are standard features. The expander shelf comes with a ribbon cable and connectors to link
the signals between the two units at their rear panels. It also comes with bus bar links to
parallel the rectier output bus bars.
The base and expander shelves can also be operated as a battery backup, single feed power
system (without load circuit breakers or fuses).
The remote access controller has LED visual indicators and Form C relay alarms. It is
programmed by means of a remote PC web page display with communication by Ethernet
LAN. Temperature compensated rectier output is provided by means of an accessory TC
probe. The X75 can be quickly installed by a qualied technician.
