DPB1U & DPG1U SERIES
DC POWER DISTRIBUTION PANELS
1.0 INTRODUCTION
These distribution panels provide protected power distribution to telecommunication equipment.
They offer fuse or circuit breaker positions on the A and B sides of the panel. The A and B loads
of the distribution panel are totally independent and isolated from each other. There is a green/red
LED for each load to indicate normal operation or an open circuit due to a blown fuse or tripped
circuit breaker.
The panels are only 1.75 inches (1 mounting position) high to minimize rack space and can be mounted
in either a 19- or 23-inch relay rack with corresponding brackets. They can be mounted from the
front of the rack with offsets every ¼-inch from front to back to align with existing rackmounted
equipment.
Figure 1 shows the two series of panels. The first is the DPG1U Series which has 10 GMT fused
circuits on both A and B sides. The second is the DPB1U Series with up to 6 circuit breaker circuits
on both A and B sides.

The panels can be configured for 12, 24 or 48 volts and are polarity neutral. Because the A and B
sides are independent and isolated, they can be configured separately. For example, the A side can
be 48V and the B side can be 24V. The voltage and of each side must be configured at the factory..
Each bus (A and B) has a green/red visual alarm and one Form C relay alarm contact for connection
to external audible or visual alarms.
