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)
