AC 220V 400W Motor Speed Controller

The US-A-52 regulates AC motor speed on a 220V supply with a 400W rating. It provides pinpoint control and supports forward and backward operation at 50 or 60Hz. This internal component suits industrial or workshop equipment needing variable speed.

Users needing precise AC motor regulation

Buyers who require DC motor control or a lower voltage input should look elsewhere. The unit does not suit applications exceeding the 400W power limit or those needing wireless or programmable interfaces. Installers without mains wiring experience should seek professional assistance.

Questions about this item

What is the maximum continuous power the US-A-52 can regulate before it hits its limit?

The unit is rated for 400 W, so sustained loads above that level will exceed its specified capacity.

How much heat or noise does the US-A-52 produce when running at full load all day?

The controller contains no fan or active cooling, so it operates silently; heat output scales with the load up to the 400 W rating.
