STUDIO COLOR 575s ~ Can a 208v be made 110v?

Hi! {my 2nd first post, lost the other one, please be kind}:o

The production house I work in has a group of sco 575s units. Most of them are 110v, and two 208v. I recently started to go through to PM all the units and discovered I have a 208 & a 110 in the shop in various stages of destruction. It was brought to my attention a question of would it be possible to take the PCBs from the 110v unit & swap them out with the 208v unit to create an operational 110v unit to be put back in service.

I will be testing the 110 boards by swapping them 1 by 1 with a known good unit to make sure they are usable. But is there anything else on the 208 unit that will not play nice if the boards are converted with the 110s?

Thanks!

    If it has a heatsink on the back, it's not an "M" - the "M" variant has the square, non-beveled edge yoke arms, and a flat plate on the back, with a magnetic ballast inside, on which you can change taps for 208/240 and 50/60 Hz. You mention boards on the end caps - one is the DMX input card, no raw power on it whatsoever. The other end has the Motor power supply (kinda beefy looking). The logic card is on the face with the display, obviously, and opposite it would be the switching power supply for the lamp, or a blank plate if it's an "M" . . .

    Now repeat after me slowly: There is NO SUCH THING as a voltage-specific component in either an S or a 575! Read the schematics! The only place the power supply voltage touches in the motor supply (switching - multi voltage capable, even in the "M") and the lamp supply - fixed in the "M", and multi voltage on all others (100 to 230V AC, 50/60Hz, as per the manual). Bottom line is that you should be able to swap any card to any unit and run any voltage . . . . even the motor supply, logic, and DMX card on an M will swap into an S at any voltage it chooses to run . . . the *ONLY* limitation is the magnetic lamp ballast in the "M"!

    The logic cards are the same in the M and S, and have very subtle differences in the 575 series.

    So, the procedure to change a 208 volt unit to a 110 volt unit is to simply change the plug to the appropriate device for your rig . . .

    Don't believe me and keep wanting to do it the hard way? Read the schematics and specs from HES here:
