Rectifier Board Module, 0-220V AC to 0-311V DC 10A Universal Mutiple Protection Against Lightning Circuit Rectifier Board Module

Was most impressed with this rectifier. As with most things, i connected it to the mains via my Variac so as to increase the input gently, and using a ordinary 60 watt light bulb as load while measuring the output voltage with my multimeter. Output voltage is quite a bit higher than input so be careful! A few examples - In 15v, out 26v; In 60v, out 86v; In 100v, out 137v; In 130v, out 176v; In 175v, out 236v. There i had to stop of course as light bulbs are only 240v. There are no controls on the thing itself, you have to control it with additional pieces, easy enough. It is built for safety - there are no bare contacts anywhere. Very pleased i came across this one!
