DESCRIPTION

The Gravitas DSC1000 is a remote access system controller for telecom power systems. It is used to digitally control and monitor a communications center/site power system. In particular it can be employed with Unipower Telecom's Sigma, Radian, and Ranger Series rectifiers. Embedded versions of the DSC1000 are also used in Unipower Telecom's X75, X100, X150 and X300 Compact DC Power Systems.

The DSC1000 is only 1U high and features local or remote control and monitoring of 12, 24, or 48-volt power systems. Communication is over an Ethernet connection or SNMP (Simple Network Management Protocol) as an option. The unit can control and supervise up to 64 rectifiers in 16 shelves.

The front panel has an LCD matrix display, 16 LED indicators and an 8-key touchpad. The controller can be programmed via the touchpad and 16-character, 2-line matrix display or by means of a PC web page display. Other features include up to 8 Form C relay alarms, battery temperature compensation, up to 8 digital inputs for monitoring, and control of 2 low voltage disconnects.

The rectifiers are controlled via I²C data over a common 4-conductor telephone cable with RJ11 connectors. A large number of system operating parameters are measured or monitored by the DSC1000. The units are shipped with default settings for 12, 24, or 48-volt operation.
