Phase detection option

The FR-A8AVP converts the FR-A842 inverter into a high power factor converter. In combination with the FR-A8VPB-H, the FR-A8AVP can send phase and voltage information about the commercial power supply to an inverter connected to the FR-A842 converter. It is not possible to use any other plug-in option when the FR-A8AVP is installed on the FR-A842 converter. All terminal options become unusable too.

Phase detection transformer box

This is a stepdown transformer acquiring phase and voltage information about the power system to send to the FR-A842 converter.

Dedicated filter capacitor
