Re: INVERTER SPECIFICATION FOR SINGLE TO 3 PHASE

John, derating isn't necessary on many VFDs of 3HP or less. Most of
them have an over built input circuit that can run full output power
from single phase input. Take a look at the Teco FM100 series. They
are available from

www.dealerselectric.com

for a good price. Ask for Harold.
