3 PHASE SYNC BOX

The 3PH-B400D is designed to convert two KGS Electronics SPC series inverters into a 115 VAC, 400 Hz DELTA three phase power source with 60 degrees between phases. A transformer can be used to realize 120 degrees between phases. The 3PH-B400W will convert three SPC series static  inverters into a WYE 115/200 VAC, 400 Hz three phase operation.

3PH-B400

One of the static inverters is employed as a master oscillator synchronizing signal and is fed into a transformer phase shift circuit. Two signals (one 120 degree leading and 120 degree lagging) from this phase shifter are then connected to the oscillator synchronization circuit of the slaved inverters. The 3PH-B400 provides isolation between the oscillator synchronization of each inverter, thus each inverter will operate individually even though the load may be unbalanced.
