2. DESCRIPTION
The AC/DC Power Supply/Battery Charger provides
-54 VDC to the Power Supply Unit in the TA 750/850
Chassis. The PS/BC receives 115 VAC through a
standard plug and wall socket. The unit works in
conjunction with an optional ADTRAN backup
battery pack, P/N 1175044L1, L2, L3. In this
arrangement, the PS/BC maintains the battery at peak
charge of -54V. If AC power is lost, the unit
automatically transfers power from the battery pack
without interrupting service. When AC power returns,
the unit switches back to AC power and recharges the
battery to peak charge.
This device complies with Part 15 of the FCC rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference,
and (2), this device must accept any interference that
may cause undesired operation.
Changes or modifications not expressly approved by
ADTRAN could void the user’s authority to operate
this equipment.
