Product description

Size:AC110V 4000W

Parameters:
Operating voltage: AC 110V
Max Power: 4000W (Connected resistive load)
Voltage Regulation: AC 0V - 110V Adjustable
Size: (shell) length 91x wide 59MMx high 34MM
Usage:
This product is Connected to 110V AC input, The output is connected to the electric wire or electrical appliances,
Rotary potentiometer rotating rod,
Can play speed, pressure, temperature control effect
Application:
This product uses the new two-way High Power SCR,
Because the design of the current max up to 20 A
A good solution to cool down the situation in the electric wire
Resistance is too small to cause over-flow problem;
Can easily adjust the output voltage 0-110V
Such as:Furnace,Hot water heater tune,Lamp dimming,Small motor speed,Electric iron，thermostat and so on.
So as to achieve dimming, thermostats, adjusting the voltage effect.
Can be used for electric power appliances use less than 4000W
Inductively or capacitive load power should be reduced, the regulator is equipped with two-way high-power thyristor, potentiometers are with nuts and thick oversized radiator with aluminum shell
Note:
Note that the load can not exceed the maximum power, otherwise it will burn modules and appliances;
Try using a resistive load;
Inductive, capacitive load power to stay for more than half margin.

Over Rated Capacity. NOT 4000 watts.

January 10, 2017

Size: AC110V 4000WVerified Purchase

The manufacturer has greatly over-stated the power handling capacity of the controller when describing it as a 4000 watt controller. It will just BARELY handle a 2000 watt load. I have many certifications in electronics, so such things are not a mystery to me.

This device is very similar to your typical light dimmer, being a common variable voltage controller built around a triac semi-conductor. The power handling capacity is limited by the maximum "junction" temperature of the triac. The triac conducts all of the current, which causes it to heat up. The maximum safe junction temperature of these devices can vary from 100 degrees centigrade (cheap ones) to 150 degrees centigrade (very expensive ones). The "finned" aluminum device is a heat sink to radiate heat away from the triac. By the time you factor in the inefficiencies of device-to-heat sink conduction, the maximum allowable heat sink temperature is mostly likely to be something like 90 to 120 degrees C. Since this is a very low-cost device, it surely incorporates the cheapest possible version of triac. Without knowing the exact component specifications, my educated guess is that when the heat sink temperature reaches 100 degrees centigrade, the device has reached the power handling limit.

I connected the device to various loads and carefully measured the heat sink temperature after allowing time for the temperature to stabilize. With a 1500 watt load, the heat sink temperature stabilized at 65 degrees C, which is fine. With a 2100 watt load the temperature stabilizes at 102 degrees, which was probably maximum continuous load for reasonable product life expectancy. With any higher load, the max heat sink temperature starts to rise VERY fast. This indicates that the heat sink is under-sized for any larger load. From a cold start, with a 3000 watt load connected the heat sink reaches 100 degrees centigrade in 7 minutes. There is NO WAY this device can be accurately described as a 4000 watt controller. It might handle a 4000 watt load only for 30 seconds or one minute, after which it will need 10 or 15 minutes to cool down.

My conclusion is that this device will work just fine with a load less than 2000 watts. At that, the user should be sure that it's not placed in a enclosed box. Free air flow is needed to allow heat to escape through holes in the cover. If you want to put this device in a closed box, you would be wise to limit the load to less than something like 1000 or 1200 watts. If you really want to extract more power from this unit, you can remove the perforated cover and use a fan to blow cool air through the fins of the heat sink. That will gain some capacity, but I haven't done the tests to be able to estimate the improvement.

Even though it's over-rated, this device works for my application which is to control a 1200-watt heating element. I suspected these ratings were much exaggerated, which is my I bought the 4000 watt version and not the 2000 watt version. This would be a 4-star item if the vendor had not exaggerated the ratings. It is reasonably well built and fairly priced for a 2000 watt controller. Even then it would not reach 5 stars because the vendor provides nothing in the way of documentation or instructions for people who aren't already familiar with these devices.

Overrated.

August 17, 2017

Size: AC110V 4000WVerified Purchase

Did not work out of package. Not sure if it was over powered by motor. But motor was well within advertised ranges for product. Instructions for wiring are basic at best. Beginners might start fires with instructions given. Would not recommend. Spend a little more to get a better quality product.

Hacked a Wilton Candy Melter for Tempering Chocolates

June 27, 2016

Size: AC110V 4000WVerified Purchase

I have a Wilton Candy Melter that was too hot, even on the lowest setting, to deal with chocolates. I bought this regulator and patched it in to the power cord of the candy melter and now I have fine control of the temperature. I also added an LCD fish tank thermometer and am now able to temper chocolates with ease.

Don't use the whole 10000 watts

June 19, 2017

Size: AC110V 10000WVerified Purchase

Though I doubt I would want to try the full advertised 10000 watts rated, it does a fine job regulating my 400 watt bench grinder. The SCR (a triac really) seems fair quality, is well heat sinked and has an internal fan for cooling. Has no connection for the ground so be careful. The instructions translated into english will make you smile.

This product is awesome. Incredible package for a nice package

Size: AC110V 10000WVerified Purchase

This product is awesome. Incredible package for a nice package. I have not maxed this item out, but it easily handles 1200-1300 watts. I highly recommend it. A real steal of a price. I used it for a lab heating element with 8ohms resistance.. and 120v AC line input. It is perfect.

Simple versatile a.c. motor control.

A simple good motor control. Useful in slowing down smaller motors in the smaller horsepower range.I believe I used this control on a 1/2 to 1 horsepower a.c. motor.

Product did not work. Didn't reduce voltage, not even one volt.

Very disappointing. Product did not work. Same voltage at output as at the input regardless of how far up or down the rheostat was turned.Read more
