Modifying Smarthome Powerlinc controller

1132B to 220V

Read the General principles for modifying to 220v

Divide capacitors value by a factor of two (choosing 630V at least). 

For all modifications, take care of the fact that you are working on "line voltage 220V". 
Don't try to plug your work until you closed the box and screwed it. 

This page is for information only, all the modifications that you perform on the original module are AT YOUR OWN RISKS.

 
  • Unscrew the four screw at each grey box corner.
  • Disassemble the board from the grey box .
  • Remove the original 130V MOV (blue disk left bottom edge picture)
  • Remove the capacitor labeled on the board C1 & C3 (brown capacitor at bottom right edge of the picture).

Note : most of the time unsoldering transformer is not required but was performed in our case to increase the visibility.

Hint : If you plan to unsolder the transformer, draw an arrow on the top of it to easily remember the correct fitting when you will assemble it back.

Converting  transformer layout to 220V will be performed by putting in series the two 115V primary coils which was originally in parallel.

To do so, cut the two tracks highlighted on the picture by the yellow pencil (first is on the capacitor side, second on back side).

 

 
Prepare the required replacing components :

1 x 330 nF 630V fit in C3
1 x 100 nF 630V fit in C1
1 x 240V (or 275) MOV (also named varistor)

(new components on left side)

 

 

Solder them at their respective places

Result should look like :

Last part of the transformer voltage modification consists of adding one wire between the two coils. (if rightmost transformer pin is considered as 1, you should bridge 2 and 4)
Reassemble the module and plug a 220V plug adapter.

It's now ready to use !!!!
