Ebay power controller

I came across this teardown of an Ebay power controller that some people here seem to use.
In a nutshell its a surprisingly good unit but way over rated as it only has a 10A fuse so max power would be a bit over 2KW before it blew.

Thx for sharing.

I'm starting to think electrical work is quite fascinating ... !

He has some quite good tutorials on his channel. I also find it reassuring that he actually says so if he doesn't understand something and he finds out instead of just bullshitting his way through.

I rigged one of these up, seems to work quite well on the std T500 element, havent tried it out on the new 3kw one though.Seems to be good value for money, if she dont blow.

I'm no electrical engineer, but the black transistor type thing and heat sink looks a bit small to handle 4KW at 100% duty cycle - I could be wrong!

The triac is actually way overkill, it's rated at 40A continuous, 400a peak. I agree with the heatsink though even though its only acting as a switch bigger would be nicer. All of which is pointless when it has a 10A fuse (probably so it blows before your powerpoint).

The fuse will blow on 3kw

Flower, thx... wasnt going to run it flat stick at 3kw, just as a controlled backup/booster. Thx for the heads up on max power... will keep an eye on it.

I got a similar one, but went for 10kw as I count on it not having strict quality control, I run a 5kw element with it fine

You have a 25A 240V, a 50A 110V or a 10A 500V power point ?
That is a serious amount of power to be playing with.
