Closed loop stepper motor kit power supply

[the great waldo]

What's the primary coil rating of the toroidal? If 220V then you might be well over the design limit of 48V with a 240V supply.

Personally, if the rectified voltage was 49-50V I probably wouldn't lose sleep over using them myself, but would never design around this for a third party.

Hi Doddy
We have 220 volts here in Austria,
cheers
