Device Description
APM30 The APM30 is an integrated power system for outdoor use and
has the following features:
zSupporting -48 V DC and 110/220 V AC power supply
zProviding at most 12 U space for user equipment when not
configured with additional devices
zSupporting internal storage batteries in the case of AC input
zSupporting piled installation with the storage battery cabinet
(under the APM30 cabinet), which is optional
DCDU The DCDU is a power distribution box and supports one DC
input and nine DC outputs.
