Voltage spikes to double the limit
I have a cheap adjustable power supply, qw-305d.
When you power it up it goes super sayian, jumping to 62.8v. Then creeps to 0.
No signs of blown capacitors, potentiometers read the correct value, except one reads 10.76 when its a 10k. Fuses are good.
What am I over looking?
Is this a good question?
