The digital voltage regulator will work wherever smooth power regulation of various devices is required, such as electric motors, fans, power devices equipped with a transformer, e.g. battery chargers, welders, migomats, etc. An additional advantage is that the regulator can control devices with a power of up to 4kW (that's really a lot) everyone can use electronics a bit, without problems, it can significantly increase the power of such a regulator, replace its 40A triac with, for example, a 100A triac, only then you should remember to significantly thicken (lead) the power input and output paths ( so that the path does not burn out at higher currents). I recommend

Unfortunately no connection plan included, soldering points should be checked (many long pieces of wire, too long and bent by the components, resulting in short circuits). Part is life-threatening if you are not familiar with electronics.

It came with the bad triac attached to the heatsink and it had a bad solder. At 1000w incandescent bulb, something went wrong. I changed the triac and it works fine.

Product not tested yet. The packaging is good, the product appears to be intact.

I can't test at the moment. Later I will leave the review on the functionality

Works perfectly I am satisfied recommend Thanks joom

It has no wiring diagram or principle.

The board is complete crap and doesn't regulate the voltage correctly. Don't buy it.

The engine power drops greatly. It might work for light bulbs.

Very good thanks

Blok did not test

does not work
