Big Clive did a tear-down of the Fotek brand. Yep, triacs. IIRC, he thought they were not absolutely terribly designed, but that their specs were definitely overstated. I won't buy/use them. I built a reflow oven, using a PIC MCU. The SSR that I used (a known good brand) only required 7mA to drive it. Meaning, I was able to drive it directly off of a MCU pin. Easy-breezy.
I am a bit confused about what you said about the resistive load vs. inductive load. In your formula you devided the 12A with 0.2 which is ended up 60 (this is clear), but when you are talking about resistive load you are saying with 0.35 we would end up with 8A, I have the impression that's not true if we are following the same formula. 12A x 0.2 = 60 8A x 0.35 = 2.8 21A x 0.35 = 60 So actually with resistive load this model can be used up to ~21A right? There are models with 0-5VDC, so those we can control with the voltage right? So 2.5 volt vould basically divide the load into half? Thanks for the good video.
Electronic control of tankless water heater: Use a PID? SSR vs SCR? I have an 8KW Atmor tankless water heater that has two switched heating elements. I want to add stable electronic temperature control. But I can't find good information about the different options! Seems the PID + SSR MAY have longer switching time, and that MAY reduce heating element life from thermal cycling vs a higher speed SCR. But I am having trouble finding the real answer.

The Fotek he tore down was a counterfiet

The resistive coefficient is 35% the max resistive load for this 60A unit is 21A , I had 15% in my head.

Why can more and more ssr are. Demeji which problem
Hi, does SSVR can maintain 220VAC going to the load even though the main supply is ranging 220-250VAC?
It follows the main voltage supply.
