Unipower offers ultra-compact 200-A 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
