Fast delivery of the Spanish warehouse, the same product as described in the ad, controls the speed of AC motors without greatly increasing current consumption.
works really well, w use it to reduce power of a slow cooker in combination with a watt meter. This way we can set the desired power input correctly
Chinese lettering, but it does not take a rocket scientist to figure out :) Works as described, has already been invaluable for repairs and troubleshooting.
Happy with item, works fine only the adjustment knob is missing.
