UNIPOWER Corporation has announced a new modular DC power system designed specifically to meet the exacting requirements of telecom systems applications where reliability, flexibility and battery back up are key factors.

The Gravitas X410R DC power system is built around a compact 600 x 600 x 2134mm or 2’ x 2’ x 7’ (48U) freestanding enclosure incorporating 8 positions for hot-swap rectifiers, AC input distribution/protection, DC load distribution/protection, low voltage battery disconnect, battery distribution/protection, system controller, and two or three shelves of front-connect batteries rated up to 185AH each. A vertical space of 12U rack height has been allocated below the power components for optional equipment such as inverters or DC/DC converter shelves and their distribution/protection panels, customer supplied equipment or for an available third battery tray.

According to UNIPOWER’s European Marketing Director, Nigel Frey, the new DC power system supports 48VDC loads up to 400A (21.7kW) and can accommodate a variety of AC inputs from either single or three-phase sources.

Commenting on the launch of the new DC power system, Nigel Frey said, “This new mid-size DC power system will interest anyone looking to put together a telecom power source that can be specified to meet their exact needs and is simple to install. Users will also appreciate the system’s front access battery terminals and field installable circuit breakers.”

An important feature of the new Gravitas DC Power System is the facility for up to 36 load circuit breakers. This is more breaker capability than many other similar systems available, representing a real advantage for many applications . These 36 field-replaceable breakers can be connected to external loads as well as internally installed equipment.

The Gravitas X410 is available either as an open rack or as a fully enclosed system with top cover, removable side panels, lockable, hinged rear door and a convenient lockable, double front door.

All UNIPOWER Corporation Gravitas power systems meet the requirements of all relevant safety standards including UL60950-1, CSA22.2 No. 60950-1 and EN60950-1 and are RoHS compliant. Product is currently available from UNIPOWER Corporation’s factories located in the U.K. and the U.S.
