1.0 INTRODUCTION
Gravitas X100 is an ultra-compact, integrated, DC power system. It consists of up to
three high power-density, hot-swap rectifier modules which can produce up to 66 amperes
at -54.4VDC, 99 amperes at +27.2VDC or 100 amperes at +13.6VDC. In 2+1 redundant
operation the output current is up to 44 amperes at -54.4VDC, 66 amperes at +27.2VDC or
100 amperes at +13.6VDC.
The system has a configurable DC distribution panel with options of up to 10 load circuits
protected either by GMT fuses or circuit breakers. Two battery breakers and a low-voltage
battery disconnect are included as standard. The system also has a temperature probe for
temperature compensated output from the rectifiers and an optional second probe can be
used to monitor external temperature.
The intelligent control and supervisory unit communicates directly with the rectifiers to
monitor and control their function. The system can be controlled by software from a remote
PC via the Ethernet LAN port, using an on-board WEB server which can be accessed by
any standard Java enabled WEB browser.
The complete Gravitas X100 is only 2RU high (3.47inches or 88.1mm) and is easily installed
by a qualified technician. All connections are at the rear to terminal blocks. The unit may
be mounted in a 19 or 23 inch rack.
