Welcome to a new voltlog, the first one in 2019 and what better way to start the year than with a InTheMail video the series that will touch both your passion for electronics and your bank account at the same time. As some of you might know I’ve recently created my patreon page so for those that would like to support me making these videos, you will find a link the description below, any pledge amount is appreciated, even 1$, just imagine half of my subscribers pledging 1$ a month. And if you can’t offer any donations, that’s fine too, my content will continue to be free.

Hello everyone and welcome to a new InTheMail the series that will touch both your passion for electronics and your bank account at the same time.
We’re gonna start with this interesting looking controller type module. So we got what looks like a big switching device here that probably needs a heatsink. Well this is a beefy triac, it can do 100A and can also withstand 1000A non repetitive peaks. We’ve kinda started from the wrong side, from the output but that’s what stands out from this module. We have an opto-isolator which has a triac output driver, separating the two sides of the board. Let’s check the clearance on the back, they have something like 3mm clearance in this area. If I were to design this, I would have done it with at least 5mm, I don’t see the point of extending this ground poor so close to this track which is on the hot side.
Links for all of the items can be found in the video description on the youtube page.
Get your account ready because here comes a new InTheMail and there is a good chance of finding something to order in this video. Don’t forget to use the links below to find the items shown in the video.
