If you have bought a Philips/Fluke PM2811, PM2812, or PM2813 power supply from a country who's electric grid runs at a different voltage, you may want to modify your power supply, to match your electrical grid (instead of using a transformer).
Provide a concise description of the issue here. Be  as specific as possible to help readers quickly determine whether or not this is the exact problem they are facing.

Problem description

If you have bought a Philips/Fluke PM2811, PM2812, or PM2813 power supply from a country who's electric grid runs at a different voltage, you may want to modify your power supply, to match your electrical grid (instead of using a transformer).

Solution

These power supplies are internally configured to one of the following ranges:

  • 94V .. 130V (a.k.a. nominally 110V)
  • 190V .. 255V (a.k.a. nominally 220V)To switch the voltage of the power supply between 110V/220V configurations you have to take the following actions:
  • Move the black jumper wire on the "Input Module" PCB, to the correct jumper. (this is marked via silkscreen on the PCB)
    • (Note: the service manual forgets to mention this)
  • The blue (bl) wire of the cable loom DB1 must be connected to
    • X4106 for 110V operation
    • X4102 for 220V operation
    • You can see the location of these pins on page 63 of the service manual [1]
  • The fuses must be replaced. The required fuse current is different for each voltage configuration:
Required fuse value
  • Please write on the back of the unit the current supported voltage.
