Hi, I have SOLA Power Supply. When I switch it on with load it does not work. If I turn it on without load and after connect ones it works good. Can anybody give some advice? Thanks in advance. IMG_20150825_133551.jpg

check the low ohm high watage resistors, one is to measure current for over current protection. I have found those burnt before. its a switching supply. check the setting of the over durrent adjustmentl.

The place where the powerful resistor of 100 ohm installed is burned, but the resistor was good. Despite this I replace it with new one. The same problem.
