Title: Portable EVSE Repair Part Struggles
Post by: romantronixlab on June 26, 2022, 11:31:00 am
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.

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

I think that the manufacturer has a store on Alibaba https://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.

It is not a medical device, it is an electric vehicle supply, opening the part could be an option unless it is poted or silicone cased.

Did not think they might have a page on Alibaba, was looking at Aliexpress. Big Difference. Thank you

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.

Hello all
The part arrived, and I was able to complete the repair of the EVSE. At first, I thought the parts were being returned to sender but were transferred to US Postal Service from DHL. The thing is it arrived well before ETA and happy about that.
EVSE is repaired and working, Once again Thank You all for the help.
