Hello
I’ve got my hand on a Velleman handheld powersupply, dead at arrival due to some missuse from the first owner…
Though it would be an easy fix, just some shorted mosfet as always but when I opened this powersupply it got really roasted,
My first guess is that the first user backfeed higher voltage to the intakes…
When i connect it to mains I just got 37vdc at the outlets, this confirm shorted mosfet.
Is there anyone that knows the values of component LR1 and LR2?
/Best regards Fredrik
