The Gravitas X200 DC Systems from Critical Power Supplies.

Gravitas X200 is an ultra-compact, integrated DC power system. The base system is a 2RU shelf holding up to four high-efficiency hot-swap rectifier modules. This system produces up to 148 amps output at -54.4, 27.2 or +13.6VDC. It can also be operated as a 31 redundant system. The 92% efficient rectifier modules cooled by a fan that operates at a speed which is a function of load and temperature, keeping acoustic noise to a minimum.

There are up to 10 DC outputs which utilise pluggable circuit breakers rated up to 60A which are fully field replaceble. Two battery string breakers and a low-voltage battery disconnect are standard features.
There are two expansion options, each housed in a 1RU expansion enclosure. The first increases the number of load circuits to 20 as well as providing support for an additional two battery strings, while the second houses an additional four rectifier modules and increases maximum system capacity to 220A.

The remote access controller monitors the system parameters and has alarms for system failures. There are four LED alarms which indicate a failure: Major Alarm, Minor Alarm, AC Failure and Rectifier 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 trap option. It also has provision for temperature compensated charging of an external battery using a supplied TC probe.
