DESCRIPTION

Unipower Telecom's DPK1U Series of Type KTK fuse distribution panels provide distribution and overload protection for 5 or 10 circuits. The one mounting position high (1.75 inches) Type KTK fuse panels provide 5 single-bus fuses or 10 dual-bus (A&B) fuses (5 per bus). They distribute 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 panel are isolated and can be separately configured for 12, 24, or 48 volts, positive or negative ground. Fuse sizes are 0.1 to 30 amperes.

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

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.
