The 100121A-01 Power Supply incorporates a rechargeable Lithium-Ion battery (BB-2557/U) to provide battery operation in addition to worldwide power applications for the newest transceivers presently being fielded by the U.S. Military.

Each unit includes one Transceiver Power Supply unit, one Lithium-Ion battery pack, one AC input cable, one DC input cable and one Operation/Maintenance Manual.

Transceiver operation from almost any worldwide AC power source (including aircraft or generator power). External 26 VDC output for amplified speaker or other 26 VDC applications.

Internal BB-2557/U battery allows for the operation of the transceiver independently of the external power source. An internal charger allows the100121A-01 Power Supply to recharge the battery while the transceiver is operating from an external AC or DC power source. To assure a positive recharge of the battery, each string of battery cells is recharged independently.
