As a follow on - I am pretty sure the problem lies in the encoder/display section and that the PSU board itself is fine. The voltage matches what is displayed but the display ( ie voltage setpoint ) has a mind of its own and jumps between 2 constant values above and below the initial setpoint. After many minutes it settles down and operates normally. I expect this will get worse over time but might be indicative of the problem now. If I had not exhausted my freeze can supply I would be hitting the electrolytics to see if I could identify a bad one. The board is all surface mount and really the only thing I have a chance of replacing are the larger electrolytic cans (still surface mounted) as I have twisted similar ones off in the past and replaced with through hole units. |
