conversion problem

[Guest]

hello we have here ricoh recycling machines like 4022,5832,5535 but all these are for 110 volt ac.but here in our country electricity is 220 volt ac.i want to convert power supply and lamp regulator into 220 volt, ac so that machine can work on 220 volt ac ,please hepl me in this regard,

Better use stepdown transformer for providing supply to machines .you can make it as a center tap transformer of 110/220v .

Stepping up the voltage is one thing and pretty cheap to do but what you have to be concerned with is the cycles. Here in the US we use 60 Hertz and if your 220V supply is 50 Hertz you will have a problem. A cycle converter is available but far from cheap. But if you dont do it, the AC motors will run just slow enough to indicate a jam and the lamps will be a little slower to heat up. The DC is not a problem as those machines use a switching power supply.
Deal with the cycles.
