The product required is the Inverter/Control Assembly Test Set (P/N: 16U4255-1, NSN: 4920-01-097-0452). The test set consists of circuits to functionally test and isolate faults of the inverter/control assembly which consists of a battery control unit, and inverter, and a NI-CAD battery assembly. The test set monitors power inputs from aircraft essential dc buses 1 and 2 and, in the event of loss of these inputs, automatically switches to output of the emergency generator converter unit. In the event the voltage of these power inputs is less than the battery voltage, the inverter will switch to the flight control inverter battery assembly as a source of power. The test set simulates these signals to the inverter/control assembly and monitors outputs of the assembly. The inverter/control assembly can be tested with or without the NI-CAD battery assembly. The test set will simulate both a good and malfunctioning battery assembly. Surplus is acceptable as long as it is new or reconditioned. As long as the equipment is fully functional and operates according to instructions in T.O. 8C3-11-3-7-1, surplus equipment in either state is acceptable.
