Power
The PSQ uses a single phase power supply. Internally the power supply voltage
is changed to:
• 242V AC for the low voltage power unit and the main drive motor
• 230V AC for the shuttle positioner motor and the bridge motor.
The main drive motor is a 3 phase motor. A frequency inverter is used to change
the single phase to 3 phase.
Refer to the following:
