The Integrated Power Supply (IPS) is constructed from aviation grade aluminum and houses high reliability DC-DC and EMI circuitry with current limit protection, short circuit protection, input under voltage lockout, soft start output and inhibit shutdown. The IPS is a 5 volt 3 amp power source. It has two D-Sub mating connectors, one to mate with the Connector Docking Assembly (CDA) and the other for input connection of 28vdc, grounds, USB or RS232 from the aircraft systems. The IPS will also have a manual power interrupt via an Annunciator On/Off switch conveniently located within the cockpit. The IPS may also be used as a standalone power supply.
