Samlex SEC 1223

Vic@VicsFloridaVilla.com
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,

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.
 
Regards,
Bob, G3VVT
