Robin,
We really need Gary to reply on this, I have only ever had one test unit of these to look at and the one we had was just an 80 volt driver with an in built power module.

Gary's may be different, after all there are many driver manufacturers out there although a lot share the same technology.
The one I had was rated at 240 volts but turned out to be designed for a 220 volt power supply, as our mains here can easily get to 265 volts at peak it didn't last long :nope:
