Are you alarmed by the juicy "splattt" from your mains power point when you plug in something like a large plasma TV set? Do you some-times burn out light and power point switches because of the surge currents at switch-on? Or perhaps you occasionally trip circuit breakers because of appliance switch-on surge currents. This is a very common problem but there is a simple cure: our SoftStarter. It tames those nasty surge currents while having no effect on appliance performance.

You've asked for it many times and we have always said NO! It's too complex, too difficult, too expensive, whatever. Now we're saying YES. This Induction Motor Speed Controller is suitable for motors up to 1.5kW (2HP) and can be used to control speed over a wide range. It will save big dollars with swimming pool pumps and will be great for running machinery at different speeds. Even better, it will control 3-phase motors as well!

This tiny regulator board outputs 1.2-20V from a higher voltage DC supply at currents up to 1.5A. It's small, efficient and cheap to build, with many handy features such as a very low drop-out voltage, little heat generation and electronic shut-down.
