Four internal thyristor Modules.
Controls the start capacitor for start stage.
Controls three capacitor banks for eight additional stages.
Voltages are balanced.
Output power is increased each time a motor starts.
No need to oversize a single to three-phase converter.
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.
