Controllers for Phase Converters
Our controllers sense starting motors and boost a converter's power to accelerate a motor fast.
Controllers vary the run capacitor for balanced three-phase output voltages.
In two, in four or in eight stages.
Capacitors are smoothly selected, free of stress, at zero volt difference moments.
Converters don't have to be oversized.
Life expectancy of components is high.
Output voltages are pure sine wave.
-
E
The output power is boosted each time a load motor starts.
Motors start fast, machines ride through overloads with ease.
-
E - D
An E version without internal SCR.
Driver only.Add an external SCR module.
This is for converters >12kW. -
R
Controls a second run capacitor for two-stage voltage balancing.
Requires an external SCR module.
No need to oversize a converter. -
T
Controls the start capacitor for start boosts.
Four-stage variable run capacitor for converters up to 8kW (10hp).No need to oversize a single to three-phase converter.
Voltages are balanced for CNC, welders, inverters and other loads.
SCRs are protected. -
F
Controls the start capacitor for start boosts.
Eight-stage variable run capacitor for larger converters.No need to oversize a single to three-phase converter.
Voltages are balanced for CNC, welders, inverters and other loads.
SCRs are protected. -
F - D
F driver for external thyristor modules.
Available for 230V, 400V or 460V three-phase.Buy thyristors in production quantities.
Mount onto alu frame (small) or heatsink (large converters).
