Oh okay clears it up.
I will be using this method since it seems super cheap. Hope everything will be accurate enough for my needs.

Thank you all for your inputs.
I can't see how the MAX4081 is supposed to work with a CT really ? They just show a shunt resistor in the datasheet, and it makes to sense to me why that would be needed with a CT.
Hello, I am seeking some information on current sensing up to 150 amps.
My task is to add a simple energy measuring device to a machine, the machine runs on 3phases of cause, but since my solution should be cheap and the result don't need to be super precise, I am thinking it would be okay to...
Current limit seems to work fine and be accurate enough.
ChrisGn -> Are you sure that there is a problem with your psu?
Mine is also slow a rising, especially when cl is under 1 amp, it takes a few sec.
I think its just meant to be this way, unless you remember your unit to function different...
Hi,
Got a TIPL762A from a local store and replaced it.
And its working again now! So I am super happy, you don't now what you got until you lose it : D
ChrisGn and karesz can't thank you enough for your help!

Hi,
Impressive with all the help, very kind of you all : )
I soldered off the power transistor and tried to turn it on, and then there comes light in the display and fuses stop blowing. So I think there is a good possibility that its the faulty component.
I have been looking around for a...
I have taken a couple more photos to get a better overview.

As it looks to me, this is the source of the actual voltage to be outputted. There is a smaller transformer right behind the net...
Hi.
Thanks for the reply. I have sent a message to Farnell, I hope they will be helpfull ofcause, but I have my doubts.
So if anyone has this powersupply, I would be really happy if you could take a picture of the area mentioned before.
Thanks
Hi.
I am searching for a person who has one of theese variable power supplies.

Mine has been dead for a long time due to some highvoltage backfire.
But it would be so nice if it could be repaired.
Problem is that a resistor at R13 is blown and I am not able to read...
Hi thanks for the replies.
penrico ->
Well the condensator is ofcause a way to solve it, but I am a little unsure if the phase degree is easy enough to solve in software.
Right now I opped my resistors to 47k each, I still get the detection, and so little amps are drawn now. So it seems to be...
