Voltlog #189 – InTheMail

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.
