Power Distribution Mode +24V DC Distribution


Power Distribution Mode 220V AC Distribution


DCDU-01 The DCDU-01 supports one -48V DC power

input and ten -48V DC power outputs. The DCDU-01 supplies power to the BBU,

WRFU, FAN unit, and user devices in the cabinet.

The DCDU-01 has the built-in surge protector that provides surge protection of 10 kA in differential mode and 15 kA in common mode.

Adjustment based on the temperature and adjustment controlled by the main control unit

Fan rotation control function. The FAN unit stops the rotation of the fans when the ambient temperature is low.



SLPU (Optional) The signal lightning protection unit (SLPU), which

can be optionally configured with the UFLP or UELP, provides the signal surge protection. The SLPU is an optional module of the BTS3900 cabinet (-48 V) or the power distribution cabinet.
