Single phase voltage regulator: The A and X terminals are the input terminals, and the A and X terminals are the output terminals.
Three phase voltage regulator: The A, B, and C terminals are the input terminals, the A, B, and C terminals are the output terminals, and the O terminal is the star (Y-shaped) neutral point.
Precautions for use:
The regulator must be well grounded to ensure safety.
The input voltage should not exceed 105% of the rated voltage to avoid burning out the equipment.
When using, the handle should be rotated slowly and evenly to avoid damaging the electric brush or generating sparks.
Regularly check the wear of the electric brushes and replace severely worn ones in a timely manner.
Keep the contact surface between the coil and the electric brush clean to prevent sparks from burning out the coil surface.
