Three internal thyristor Modules.
Controls the start capacitor stage.
Controls two capacitor banks for four additional stages.
No need to oversize a single to three-phase converter.
Output power is increased each time a motor starts.
Voltages are balanced for CNC, welders, inverters and other loads.
SCRs are protected against over-voltage and over-current.
Monitors the three-phase voltage symmetry.
Capacitor selection at zero volt transitions.
