The Gravitas X100 from Critical Power Supplies 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 21 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 rectifi ers and an optional second probe can be used to monitor external temperature.
The intelligent control and supervisory unit communicates directly with the rectifi ers 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.
