ATO Single Phase VFD for Single Phase Motor 3HP 2.2kW VFD Drive Variable Frequency Drive 220V Single Phase Output VFD Single Phase Motor Speed Controller (1-Phase Input, 1-Phase Output)

I like the design. Very programmable. Self protecting. Many motor control applications. I used it for single phase slow starting motors.

Good instructions on how to set basic parameters. Bad is they don't have live tech support after purchase, only email option, not great when in the field trying to finalize install. I would say if you have a decent amount of experience with vfd and you have a basic application, these drives can definitely save you or customer some money.

This vfd worked amazing on my delta 28-640. I need to red7ce the rpms the allow speed to buld up. This unit did the trick would purchase another one if I ever come to that situation again.
