I have a SMPSU which controls a height adjustable desk. input 230V AC, Output 24V DC.
The PSU died. Symptoms: just blew fuse in mains (230V). As the mains is a bit dodgy sometimes I replaced fuse - symptoms the same.
Internally the PSU has a lot of yellow potting compound on many components, which is a pig to deal with.
Board is made by NAO technologies, board number HCSA-200 Rev A.
One resistor (PR2) (looks to be a half watt size) shows heat damage around the potting compound, but as I have no diagrams find it difficult to start diagnosis.
Emailing company has no reply.
Anyone have any experience with this? Anyone have any schematics/circuit diagrams?
