110V-240V SL-1200M3D

If you've looked at the 240V schematics for dual voltage 1210 models (which you will need to before fitting) you will understand why a 110/240V transformer has more wires. The schematics for the 110V and 240V versions also show the mains fuse and power fuses which will give you the information you need to correctly wire it up.

As for fitting the transformer, I don't know if it will fit your chassis, but as you've only bought a bare transformer you will need the bracket/grommets etc from your old transformer (if they are the same?) or specifically for the new transformer. The parts are shown in the service manuals.

Ok, just checked out the schematics for both the models and I'm gonna need new Power Suppy PCB's (ones with the voltage selector). The four wires (blue, white, black, brown) hook up to the voltage selector (on the Power PCB) while the other two (yellow) hook onto the drive control circuit (AC). The existing Power PCB has fuses rated for 110V not 220V so I think there's no way the existing Power PCB will work. I have no choice here, I'll have to totally convert my system to a dual power 110v-220v switch-able, and for that I need new Power PCB's, if they are available. Unless I'm wrong in my assumptions. What do you think JaS?

Hi,
As I said earlier, the dual voltage version has a different input board to allow switching. I only see one fuse on the M3d circuit diagram though, and it's for the 30V feed, not the mains. To wire for single voltage the only components I see on the mains side of the transformer are C601, R601 and S601. C601 would need changing to a 400V capacitor and S601 (the power switch) needs the rating on the switch checking, although this is a cheap industry standard micro switch and should have a 100/240V rating?

Ok, I think I'm ready to source a heavy duty 500W step-down transformer, I want it to last me a long long time hence 500W. Thanks for your input anyways.
