US-52 SPEED CONTROL UNIT 120W

Product Description

The US-52 Speed Control Unit 120W is an AC motor speed regulator designed for smooth and precise speed control of small single-phase induction motors. It operates on a 220V AC supply and allows stepless speed adjustment using a rotary knob, making it ideal for light industrial automation, conveyors, labelling machines, packaging systems, and small machinery applications.

This controller is part of the widely used US series motor speed controllers, offering compact design, forward/reverse direction control, and stable motor performance under variable loads.
