UNIPOWER GRAVITAS X75 Power Systems 12V, 24V and 48V, up to 75Amps
Gravitas X75 available from Dewar Electronics is an ultra-compact, integrated DC power system in both a base and expanded configurations.. The base system is a 1RU shelf holding up to three hot-swap rectifier modules. This system produces up to 1958 watts output at -54.4, +27.2 or +13.6VDC. The Gravitas X75 can also be operated as a 2+1 redundant system with up to 1305 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 rectifier modules with up to 3916 watts output; it can be operated as a 5+1 redundant system with up to 3264 watts output..
There are up to five 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 rectifier output bus bars.
The system can also be operated as a battery backup, single feed power system (without load circuit breakers or fuses).
The remote access controller monitors the system parameters and has alarms for system failures. There are six red LED alarms which indicate a failure: Major Alarm, Minor Alarm, Rectifier Alarm, AC Input Alarm, Over temperature Alarm and Overvoltage Alarm. A green LED indicates that the controller is operating. Four Form C relay outputs give alarms: Major Alarm, Minor Alarm, Rectifier Alarm and AC Input Alarm. The controller is programmed by means of a remote PC webpage display. Communication is by Ethernet LAN with an SNMP (Simple Network Management Protocol) alarm option. It also has provision for temperature compensated.
