SKU CH-JWSP-EE2YK

Controls 220V AC motor speed up to 400W with forward and reverse operation at 50 or 60Hz

  • Controls single-phase AC motors up to 400 W
  • Forward and reverse direction switching built in
  • Operates on 220 V 50/60 Hz mains supply
  • Compact internal power cable design for easy installation

400 W AC Motor Speed Controller

The US-52 regulates single-phase AC motors up to 400 watts on 220 volt 50 or 60 hertz mains. It provides forward and reverse direction control for compatible induction motors. The unit is designed for internal wiring inside equipment enclosures. It suits hobbyists and technicians building variable-speed drives for small machinery.

Replaces Fixed-Speed Wiring

This controller replaces a simple on/off switch or fixed capacitor arrangement when variable speed and direction change are required. The upgrade is worthwhile when the application needs adjustable RPM or reversible rotation without mechanical gearboxes. It is not suitable for three-phase motors, brushless DC motors or loads exceeding the 400 watt rating. Buyers needing higher power or different voltage ranges must select a different controller.

Questions about this item

What internal power cable connections does the US-52 speed controller require?

The controller connects inline between the 220V AC supply and the motor using its built-in terminals for line, neutral and motor leads.

How is the US-52 controller wired, and which step is often missed?

Wire the supply to the input terminals and the motor to the output terminals, then set the direction switch before powering on — many forget the direction step.
