Controllers for Phase Converters
Controllers sense starting motors and accelerate them.
Load motors start fast.
Run capacitors are controlled for smooth voltage balancing.
Voltages are symmetrical at all loads.
For single motors
Run one three-phase motor on single phase power.
S: Senses starting motors and boosts currents for fast acceleration.
R: Senses voltage symmetry and engages a second run capacitor.
RS: Run and start capacitor control.
For multiple motors
Control converters for multi-motor machines, CNC machines and welders
E controls a start capacitor
RS for one start and two run capacitors
T for one start and three run capacitors (five stage control)
F for one start and four run capacitors (nine stage control)
