Hi
does anybody know whether the power board (856D powerdrive V2.

is dual voltage? I have acquired a 110v version with the USA plug directly wired and I have searched the internet to see if it's compatible with 220v (label on the case 110v). However, I have seen several teardowns of the 220v version and all the components appear to be the same with the same ratings.
I know I should just buy a step-down transformer but at 1300w (and a generous PF of 0.7 for a switchmode power supply) it would require at least a 1875VA transformer and probably bigger that is a meaty and heavy tranny! Whereas if it's just a matter of replacing the plug?
If I used an auto-transformer and slowly raised the voltage anybody have any ideas how I analyse the performance to detect failure before it happens! E.g. current draw FET/TRIAC temp etc
Any help will be great
Thanks
