Unipower offers ultra-compact 200-A DC power system


Gravitas X200 expandable up to eight rectifiers

Gravitas x200 integrated DC Power System

Unipower announces the Gravitas X200 integrated DC power system designed for telecoms and other applications that require 12, 24, or 48 VDC. The Gravitas X200 is an ultra-compact system based on a 2 RU shelf that is expandable to 3 RU to provide output loads to 200 A. Standard output voltages are -54.4 VDC, +27.2 VDC, and +13.6 VDC. Gravitas X200 Power Systems incorporates up to four 92% efficient hot-swap rectifiers in 2 RU systems and up to eight rectifiers in the expanded 3 RU systems. Internal speed-controlled fans cool the rectifiers and respond to load and temperature conditions keeping acoustic noise to a minimum. The DC output circuits can power as many as 10 loads which use pluggable circuit breakers each rated up to 60 A. Two additional pluggable 100 A breakers can provide either load or battery protection. Battery protection rating can be increased to 125 A each with non-pluggable breakers. Where battery protection is provided externally, an unprotected battery feed output is provided as standard. A field replaceable remote-access controller monitors system parameters, controls rectifier output, and provides alarms for system failures. LEDs indicate major and minor failures, as well as a system-good status signal, while four form-C relay outputs provide the alarms for remote use. Gravitas X200 systems can be programmed using a remote PC webpage display and communication is by Ethernet LAN with an SNMP option. It also has provision for temperature compensated external battery charging using a supplied TC probe. An optional LCD touchpad is available for local metering, status, and set-up. www.unipowerco.com
