UNIPOWER Telecom’s DPBF1U Series of all Front Connected DC circuit breaker distribution panels provide distribution and overload protection for 8 DC loads up to 30A. The 1RU mounting position (1.75 inches) high DC breaker panels provide 8 singlebus loads or 4/4 dual-bus (A&B) loads (up to 30A max. per load). They distribute up to a total of 150 amperes of load current from two separate 150A sources with true A and B distribution and alarm capabilities.

A and B sections of the dual-bus panel are isolated and can be separately configured for 12, 24 or 48 volts, positive or negative ground. Breaker sizes are 1 to 30 amperes.

Breaker alarms are indicated by a red LED for each bus and two Form C relay contacts per bus with multiple connection points.

The panels come with brackets that permit mounting in either a 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.
