Quite a few of you are using the Samlex SEC 1223.
I have a European version with 240v input. There is supposed to be a pair of jumper points inside which allows you to switch to 120v input. I can't find my handbook . Can anyone confirm the two jumper point refernces and also where are they located on the board? Many thanks, Vic GW4JUN K2 1926 _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list. Subscriber Info (Addr.

Reply ------------------------------------------------------------------- Hi Vic, I had the same problem when taking a European version to Saudi Arabia and ended up contacting a technician in Samelex America for the info. To quote their reply: "The European model is permanently set for 230V 60Hz input (the manual you have is for the American version) Conversion to 110V can be done by a technician. It will be at your own risk and will void the warranty. For conversion to 115V, the terminals "C" and "E" on the circuit board are required to be connected together (shorted). The brown wire connection from one side of the interference suppression choke to the male terminal post at point "C" should not be disconnected. You may connect another piece of wire between points "C" and "E" (aim is to short points "C" and "E"). You will have to solder these connections using 18 AWG wire as we do not have a special jumper for the European model. Also you should increase the fuse capacity to 6.3A in order to draw the full 23A at 110V input. 4A fuse is used when powering from 230V. !!!!!!Remember to undo this modification if you are going to convert it back to 220V operation otherwise you will blow the unit !!!!!!" So Vic there you have it as described by Samelex in 2001 when I was in the same position.
