Ultralife a-320v1 power connector

[huskyrunnr]

The power connector on this amp has three pins. A is +24v, B is ground, but can anyone tell me what pin C is for? I’m thinking a remote power on line but I don’t want to go hooking up voltage Willy nilly without knowing for certain what voltage or signal that line is for.

Um................ What Amp? What Truck? What plane? What equipment?

The amp is mentioned in the thread title, Ultralife a-320v1. Downstream of the amp for me is a diy cable, 12 volt battery and a dc-dc 12-24 volt converter. The military uses a BB-2590() battery usually, but there are other power sources they use that I’m less familiar with. The cable for the BB-2590() battery has no connection from pin C on the amp only connection from pins A and B which are +24v and chassis ground. However, the technical data sheet for the amp says it has “remote power on capability”. The connector is a Glenair 801 Mighty Mouse with three sockets and the amp has three pins. The company won’t answer the phone.
