DESCRIPTION

Unipower Telecom's DPT1U Series of Type 70 fuse distribution panels provide distribution and overload protection for 6 or 12 circuits. The one mounting position high (1.75 inches) Type 70 fuse panels provide 6 single-bus fuses or 12 dual-bus (A&B) fuses (6 per bus). They distribute up to a total of 120 amperes of load current from two separate 60-ampere 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. Fuse sizes are ½ to 10 amperes.

Fuse alarm is indicated by a dual-color LED (green/red) for each bus and two Form C relay contacts per bus.

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.
