Product Description

Power & Speed Controller 110V / 240V

Manufacturers Notes...M028N

Loads of applications and with a 25 amp peak rating! With this power controller you can regulate incandescent lamps, heaters, heating lelements, hand drills, electric motors etc. via the supplied potentiometer. 2 operating voltages: 110vac or 240vac. The rated contstant load is 18A but can peak at 25A max. At 240vac this corresponds to 4000va. The units are PWM (Pulse Width Modulation) type controllers.

Important Note: The module HAS to be mounted on a heat sink or cooling plate if the constant load exceeds 8 amps.

Single phase motors with internal centrifugal starting switches can not be speed controlled electronically.

If it is a DC appliance that needs to be controlled, the module can be installed at the primary (input) side of a transformer which in turn will give a proportional output on the transformers secondary (output) side, thus allowing full control over the DC output too. Perfect for loads of power, voltage & speed control applications.

The power controllers are supplied with the potentiometer & leads

  1. Accurate PWM control

    Posted by Steve Murphy on 1st Jul 2013

    I am very pleased with the smooth control of the 25A speed controller. I'm using it in a temerature control circuit drawing 8A using a heatsink. It performs accurately.
