Teyleten Robot AC 110V 120V 220V 230V 10000W High Power SCR Motor Speed Controller Board Dimming/Attemperation/Voltage/Regulator/Thermoregulation/SCR Controller Board

I was not expecting very much when I ordered this power control but it exceeded my expectations. First, it has solid wire terminals to attach my 14 gauge wires. Second, the heat sink allowed for good heat dissipation. Third, it was easy to disassemble so that I could custom fit and mount the chassis. Fourth, the voltage control knob could be mounted remotely with it's 6 inch leads. I was controlling a 240 volt, 1500 watt water heating element, and this control worked perfectly.

My main purpose in buying this product was to control an infrared heater so I can set its intensity to my liking. So far, it has passed my test. In both ~75% and 100 % setting, I didn't sense in any dramatic increase in the controller's temperature and no arcing or buzzing at all. See attached picture.I also tested it on a heat gun -- not a real application, just did it as a sanity check. Using this controller, I could vary the motor speed and intensity at the same time from the lowest to highest level.Also notice that I've only tested it on resistive and brushed motor loads. Not sure how it would handle different load types.

Device needs a load. It seems to work so far on 120v. Could be a bit better quality

This was my first foray into controlling AC voltage with such a thing (used with a DC rectifier to run a 110VDC permanent magnet motor)...works like a charm, although it's worth noting that it was necessary to replace the potentiometer with a lower resistance one to achieve the desired range in volts - the original potentiometer essentially sets the bottom end of the volt range too high for my needs. But that's a cheap fix and a quick one if you're into soldering. Overall, perfectly happy with the purchase. In fact, and if anyone out there needs to cut back on the heat sink - I did to make it fit into an enclosure - I've run it for hours at a good clip (~50-60%) without overheating or burning out the controller...happy news for anyone needing to remove part of the heatsink...

I'm not an electronics expert, so I don't know if it will make much of a difference or not, but the product listing lists multiple input voltages (110V, 220v, 240v, etc.) But the decal on the side of the unit itself only says 220v!Luckily my application is 110v, so I'm not too worried about damaging the unit if it IS designed for 220, but for anyone planning on using it for 240 or higher based on the Amazon product listing, be aware that the unit itself doesn't list voltages higher than 220v. So if you're planning on using it with voltages higher than that, you may need to calculate the max wattage of this unit based on those higher voltages, as the max load listed in the product listing may be at 220V.

I was skeptical at first to control my treadmill motor, but when I added the 50 amp bridge rectifier, in turn putting a load on it, then the miracle happens it puts out about max 118v dc enough to power my 2.5 hp treadmill motor for my converted mini wood lathe.

The media could not be loaded. If you read the "Customer questions & answers", you will find out how useless it is for motor over 1/5 horse power. I think it is only useful for a resistance device.Watch the video. It's not suppose to spark like that. And in case you were wondering, I did add a Bridge Rectifier.

Not an electrics expert, so I know you *can* use 110 on a 220 device, but I'd rather not.
