    Tips: Why need to oversize the single phase VFD
    The variable frequency drive supplied by can operate with single phase input. However, to provide three phase power to the AC motor when only single phase input power is obtained, for this application, the internal components of the 1-phase VFD must be enlarged, otherwise the load must be decreased. Either way, VFDs in 1 phase applications must be oversized to withstand the increased bus voltage ripple and increased input current. If you do not oversize variable frequency drive for the motor in a single phase application, what is waiting for you will be continuous failures.


    This video includes three parts: 1. What is customized equipment? 2. Difference between non-enclosure and standard VFDs. 3. Pratical operation of ATO non-enclosure VFD. All above explains the features, functions and working of non-enclosure VFD.

    Are you aware if the VFD has had a "safety" test doen?
    Thanks again for the EMC test report. Are you aware if the VFD has had a "safety" test doen, to the relevant IEC safety standard? And also if the product was test up to 240V, that's what we have in Australia. I've also just now purchased another one.

    Our products have been strictly tested according to factory standards before leaving the factory, and the quality is worthy of guarantee. We have also done withstand voltage tests for countries such as the United States, Canada, Australia and other countries with single-phase voltages up to about 240V. Therefore, there is no problem for our products to meet the requirements of the Australian 240V voltage.
    Questions about your 1-phase drive
    For your GK3000-1S0015 and GK3000-1S0007 1-phase drive, will these take 208v without any issues?
    From: Ortize | Date: 20/01/2022
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Yes, of course. It can take 208/220/230/240V with no problem.
    Based on the situation I described, which VFD would you recommend to me?
    I have an older Rockwell-Delta lathe that has 4 variable pulleys to control speed and does a poor job of that. I would like to install a vfd to control speed and reverse it. The motor is a 1/2 hp, type c, rpm 1725, sf 1.00, V 115/208/230, ph 1, a8.0/4.0, 60 hz, amb 40c, fr 56, code j, ins b* and says it can go into reverse by interchanging the red and black wires. What do you recommend?

    Your motor is 1-phase, so it can not be reversed via 1-phase VFD, and you have to interchange the red and black wires, so you can reverse the direction.
    Very good VFD
    We brought a compressor which works in 230 volt 60 Hz maximum current will take 16 Amps. But in India we had 230 volt 50 Hz. Request your support for the right product to convert 50 Hz to 60 Hz with the same voltage level.

    You can use our 1-phase VFD. But note that the VFD can be used for motor individually not for your whole equipment/machine, with direct connection between VFD output terminals and motor input terminals, nothing in between. Also, the motor will be fully controlled (on/off/speed control) via VFD buttons only.
