Navy Model 800-1 Inverter

Also produced as the PU-43/A for the USAAF, this inverter provided 800Hz power for radar (and for the Navy, communications transmitters.) Below is a sample of maintenance and operational notes about the inverter that may help in troubleshooting your own version of this 'siren in power supply clothes'. One of the reasons for demise of the 800Hz power standard for aircraft was the effort needed to deal with reactance of the generators. More on that issue is located here.
