--- Quote from: james_s on February 18, 2019, 03:24:14 am ---Trace out a schematic of the input rectifier and filter capacitors. Quite a few SMPS designs use a 330VDC bus regardless of whether they're made for 120 or 240V. The difference is that 120V models wire the rectifier and capacitors as a doubler while 240V models will full wave rectify the input. I have converted a couple of 120V devices to 240V by rewiring the input section and adding a second capacitor, the reverse is easily done too. --- End quote --- I have said that far back in the fourth post. :palm: |

Good for you, I didn't see the 4th post, nor does it appear that this has been done. |
