Ive got a 5hp PC3 vfd running my Gorton MasterMill.
The top end voltage it is supposed to run on..is 230vts + about 5 volts
It will run down to 200 volts.
Im running it on single phase, been doing it for years.

Now the power company has increased my 220 single phase to about 249
volts and when I try to start it..I keep getting OverVoltage Alarm.

I cant get the power company to change the tap down to a normal voltage,
let alone 220 volts

How do I (cheaply) transform high voltage down 14-29 volts ac?

Id hate to loose the VFD on this mill and have to run it off a RPC
(which also puts out higher voltages)


How much current do you need? A simple buck transformer will do the
job, as long as it's secondary can handle the current.
