  • Note: This product is AC input, AC output, can only step down, and the voltage can be adjusted only when the load is connected. It is useless to connect a multimeter with no load, because it is not a transformer.
  • Motor speed controller operating voltage range is AC 110V to 220V, max power is 4000W, long term operating power is 3000W, and adopting double insulation, meaning there will be no electric leakage if short-circuit or SCR burn out.
  • Protection: our motor regulator is designed with Anti-spike and anti-surge protection, RC absorption, fuse all enhance usage safety.
  • Aluminum Case: the motor speed controller is equipped with Aluminum case prevents it from easy damagement; filled tin stops it from heating when in huge current.
  • Application: the motor governor can be applied to electric stove, water heater heat regulation, dimming lamp, small motor speed control, electric iron thermostat, etc.

DATE ORDERED: 02/06/24DATE RECEIVED: 02/14/24DATE OF REVIEW: 03/10/24PERSONAL BUY/PRODUCT TO REVIEW: Personal BuyDELIVERY: UPS - Well packaged with additional itemsQUALITY: Well, it 'looked' pretty good. But it died on the first day.INTENDED PURPOSE: The plan was to use this device to control 2 small heater strips. Total load 15 Amps (7.5 amps each) on a 120V circuit. Total wattage of 1800W (900 watts each) on a 4000W advertised product. It should have been able to handle this load with no problem based on the ratings advertised.RECOMMENDATION: On the first test, the switched worked. On the second test, it did not. This was a purely resistive load. Not an induction load. I started with the switch in the low position and slowly ratcheted upward to full. Like I said, it worked the first time. I thought I would be pleased. The second time, it locked into the high setting only. I should have expected this. Junk from China. I'd ask for a refund or replacement but that would be like pulling teeth with with a fork. Lesson learned. I rate this product as a DO NOT BUY!

Made all the motors I tested give off a loud humming sound as soon as I lowered the power.

Quit working on the second use. This is garbage, and a waste of money.

I've been working with scrs and triacs since the 1970s. I know how to use them. I wired this up carefully, paying attention to the warning that the inputs and outputs could be reversed from left to right. I connected it to a motor with a maximum load of 1,400 Watts. However it's never been my intention to run it at full power. At reaching the minimum control activation, the fuse blew like a Fourth of July fountain. I also have some variac type variable transformers rating at less than a thousand watts that do a perfect job of controlling this motor and do not overheat. I'm going back to using them. Old technology is sometimes the best.The refund did not require a return so I opened it up. First off, the fuse did not protect the Triac. It's toast. Second, the circuit seems unnecessarily complex for a basic motor controller. Regardless, it was beyond repair, and not valued enough by the vendor to require a return.

Bought and rebought this item. First one worked great. The second one looked exactly like the first but for a different color of peel off protective plastic wrap. But,,, the inputs and outputs were reversed! I didn't catch that and burned out a motor. I won't make that mistake again.
