    65hp Single Phase to 3 Phase Converter Details


    1. Single phase to 3 phase converter input voltage, output voltage, frequency and phase can be customized.
    2. Pure sine wave output, transient response is less than 50ms, waveform distortion is minimal, conversion efficiency is high, and output voltage is stable.
    3. The static phase converter uses a low frequency transformer to ensure that the input voltage and output voltage are completely electrically isolated to avoid interference.
    4. Using SVPWM space vector algorithm, high conversion efficiency, high instantaneous power, low no-load loss, conversion efficiency can reach more than 94%, and no-load loss is small.
    5. The output AC power supply is suitable for all types of appliances, power tools, motors, etc. Has a higher driving load capacity.
    6. 3 Phase converter has the function of filtering out grid interference and interference at the same time, with stable voltage and frequency power performance, and provides a more stable and pure power supply environment for back-end equipment.
    7. Complete output protection function, with output overvoltage, overload, short circuit, overheating, self-diagnostic protection and other protection functions.
    8. High conversion efficiency, high instantaneous power and low load loss.
    9. Two start modes: step-down start and variable frequency start. Customers can set the startup mode according to the load type. Reduce the use of frequency converters, thereby reducing equipment investment costs, easy wiring and control.

    Tips: The main advantages of the three-phase system

    Three phase saves wires in power transmission, it can generate rotating magnetic fields, and creates conditions for the development and application of asynchronous motors with simple structures and convenient use. Three-phase system does not exclude the supply of power to single-phase loads. Therefore, three-phase alternating current has been used most widely.

    In this video, ATO will show static phase converter converting single-phase 220V to three-phase 380V. And this phase converter has VFD technology to start the three-phase asynchronous motor to reduce the impact on the power grid.

    Existing reviews of 65 hp Single Phase to Three Phase Converter
    VFD and phase converter, which is better?
    The 34.3 kW is the absolute maximum power number that the machine only uses while preheating for around 10 minutes.
    Most of the time the machine will be running well under 30 kW of power. The hot air blower is 495W and works with a VFD.
    Almost all of the power comes from heating elements or halogen lamps used for heating, and I will list those below.

    Total 34.3 kW
    Hot Air Ceramic Heater 16 kW
    Halogen Lamp 16 kW
    Drum Heater 10 kW
    Cooling Motor 1.5 kW
    Agitation Motor 0.2 kW

    The cooling motor and agitation motor are both regular motors and don’t require a speed control like the hot air blower.
    The machine works by electrically heating a large metal drum, hot air, and a halogen lamp with 100% electric heat. As long as the voltage is 380 and stable at 60hz.
    We are still wondering if a large VFD will be better or a rotary phase converter so we will need help choosing a good solution for them. We are looking to partner with you to build possibly a lot of these to sell alongside the machines.

    ATO Responded
    1. According to the load you provide, we recommend: ATO-PHC-050 for this phase converter.
    Please refer to the link:
    2. According to our calculation, your machine needs a peak current of 240A at the input end to run, so your power supply at the input end must reach 53kW.
    Powerful enough!
    I bought this converter to use on my machining center. A solid and modernly designed equipment. It works smoothly and quite. Powerful enough!
