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.
