Question
Can three G3PX Power Controllers for single-phase applications be combined for control of three-phase loads?
Answer
No.
Three-phase loads are controlled by each having a phase angle separated by 120°, so three G3PX Units for single-phase applications cannot be used. Always use a Three-phase Controller to control three-phase loads.
Sometimes the G3PX-260E[] can be used for an open delta configuration (see the connection diagram below).
Note: The G3PX-220E[]/240E[] (20 A/40 A) cannot be used.
