UNIPOWER Unveils Gravitas X100 DC Power System

UNIPOWER Telecom, a division of UNIPOWER Corp. (Coral Springs, FL), unveiled its new Gravitas X100 ultra-compact, fully integrated, dc power system, which is designed to power a variety of telecom systems. The power system consists of three high power-density, hot-swap rectifier modules; a monitor and control section; and a dc power distribution section. The complete 19 in rack system is only 2 RU high (3.47 in) and 11.56 in deep.

Maximum system output is 60 A at –54.4 Vdc, 99 A at +27.2 Vdc or 100 A at +13.6 Vdc. In redundant mode, the output currents are 40 A, 66 A and 50 A, respectively. The dc distribution section can be configured with up to five load circuits protected by circuit breakers, GMT fuses or a combination of the two. The circuit breakers are pluggable for easy changing or upgrading of the output circuits. There are also one or two battery string breakers and an optional low-voltage battery disconnect. Temperature compensated battery charging is also an optional feature, including a temperature probe.

The controller section controls and monitors the rectifier outputs and monitors the output load circuits. It has LED visual alarms and Form C relay alarms for rectifier failure, fuse or breaker action, low-voltage battery disconnect, over-voltage, and under-voltage. There are front-panel adjustments for float voltage, battery under-voltage, battery over-voltage, temperature compensation, and test points to monitor load voltage and current.

The Gravitas X100 is suitable for use in small telecom installations requiring 12 Vdc, 24 Vdc or 48 Vdc. The “base system” is priced at $930 each, in quantities. Rectifier modules are priced at $480, in quantities. Systems can be configured and shipped within one week in small quantities.
