Meanwell - Fuse? <Answered>

Post by Chaz »

Managed to get some swarf into my PSU during some testing. No more 24/5V. There's a comment about a fuse on the PSU but I cant see it. Does anyone know if it has a replaceable fuse?

Thanks

Assuming you are talking about the RD-35B model that is shipped with Acorns and some other boards, not that I am aware of.

I took one apart and found a warning to replace the fuse with same type and rating but nothing that looked like a glass or ceramic cased cartridge fuse or fuse holder. Nor did I find anything that stood out as a resettable fuse. There was something that looked like a thermistor but I wasn't going to reverse engineer the power supply to find out what it was doing.

Protection type : Hiccup mode, recovers automatically after fault condition is removed

Remove all wiring from the DC outputs and test. Maybe there is a shortage in the wiring.

Power supplies should have circuit breakers on them.....for good reason. :D

Not a terribly expensive problem to resolve:

Thanks. Breakers did break, so that's fine. But no output. Ive ordered a new one, just hoping the Acorn board is good.

The board itself talks about a fuse, hence asking.

Just tested with no load, PSU is dead. Hopefully that's all it is. Got a new one hopefully arriving today.
