Circuit Breaker Panels

Tue, 04/10/2001 - 11:05am
UNIPOWER Telecom, a division of UNIPOWER Corp., introduced its new DPB1U circuit breaker panels that provide distribution and overload protection from 1 up to 12 DC circuits. The panels are one mounting position high (1.75 inches) and provide one to six single bus breakers or two to twelve dual bus breakers (for redundant A/B configurations). They distribute up to a total of 300 amperes load current from two separate 150 ampere sources with true A and B distribution, and come with alarm capabilities.

The A and B sections of the panel are isolated, and can be configured for handling 12, 24, or 48 VDC, positive or negative ground. Circuit breakers are available from 1 to 50 amperes.

A circuit breaker alarm is indicated by a dual color (green/red) LED for each bus and two Form C relay contacts per bus. A fail-safe option lets the A and B sides operate redundantly from two separate feeds.

The panels are 1.75 inches high, 19 inches wide and 9 inches deep. They come with brackets that permit mounting in either 19 or 23-inch relay rack. They can be mounted from the front of the rack with offsets every quarter-inch from front to back, to align with existing rack-mounted equipment.
