content: Hello to all.Recently I got my hands on a portable Lectron(Duosida) EVSE, it did not power up when connected to mains 240v and I was able to pinpoint the issue with an AC/CD converter for the controller as not working.Applying a 12v supply to the controller input pins brought it to life so I know it is not shorted.The main issue is finding the AC/CD converter 12v3w. Using the printed number on searches brought up little to no results. Any help finding this or a compatible part is really appreciated.

content: You may try disassembly and repair or another manufactures part unless this is a medical devicein which case nevermind. Noting the measurements might be a good idea for responses.Jeff

content: I think that the manufacturer has a store on Alibabahttps://aipulnion.en.alibaba.com/I didn't look for an exact replacement, but you could try contacting them. Some items have a minimum order of 2 pieces, so they might be willing to sell you just a couple of pieces.

content: Want to say thanks to all who replied. Was able to find the part. Somehow google knew I was searching for this part (google does not track? subject talked to many times) and recommended (google ads) Octopart; thru them, which is like a search engine for electronic parts, was able to find a supplier with that part. Made an order for 2 just in case and is in transit, will let you know how it went after delivery.Again thank you all for the help.
