UNIPOWER DPB1U Series 1U DC Breaker Panels

The UNIPOWER DPB1U Series 1U DC breaker panel provides distribution and overload protection for 1 to 12 circuits. The panels are only one mounting position (1.75 inches) high. Alpine Power Systems is an approved distributor of UNIPOWER products.

The panel provides 1 to 12 single-bus breakers or 2 to 12 dual-bus (A&B) breakers (1 to 6 per bus) and distributes up to a total of 300 amperes of load current from two separate 150-ampere sources with true A and B distribution and alarm capabilities.

A and B sections of the dual-bus 1u dc breaker panel are isolated and can be separately configured for 12, 24 or 48 volts and are polarity neutral.

Breaker capacities are from 1 to 50 amperes.  Alarms are indicated by a dual-color LED (green/red) and one Form C relay contact per bus.

The 1u dc breaker 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 front to back to align with existing rack-mounted equipment.
