    Tips: Why choose frequency converter?

    Since the power source of various countries in the world are not uniform, the production of export products needs to simulate the electric grid conditions of different countries to test various export appliances. In the past, the generator was used for secondary frequency conversion, but the power consumption was large, the noise was large, and the stability was poor. The frequency converter is a kind of precision power supply that converts the mains into the required voltage and frequency through the power conversion circuit. It can convert 50Hz to 60Hz or 60Hz to 50Hz, output pure sine wave, and can provide standard voltage and frequency of various countries in the world, suitable for voltage and frequency testing of export products. More and more countries select frequency converter as a standard power supply.

    Existing reviews of 30kVA 3-Phase 220v 60Hz/400v 50Hz Frequency Converter
    frequency converter
    The frequency converter that I ordered and I’m having an issue.
    The incoming voltage is 420V when measured at the input terminal lugs. I am able to turn on the input breaker and press the power button. The output voltage measured is 211V phase and 122V line. When I switch the output breaker, I get an alarm and one phase drops to 0V while the other 2 phase maintain voltage.

    You mean that the converter has one of its legs not working and no output voltage, right?
    If so, please confirm which of the U, V, and W phases has no output voltage.
    Then please refer to the attached troubleshooting document to measure the faulty fuse, IGBT module, driver board, etc. of this phase, and feedback the measurement results to us.
    Of course, before taking measurements, you can carefully check whether there are any cables loose or falling off inside the converter?
    Have you had time to give it some thought?
    Would it be possible for you to provide modules and documentation to enable us to adjust the converter for a different Input voltage as per the discussion below?

    I understand that there is hardware module/modules that needs to be exchanged to change the input voltage, correct?

    Unfortunately, shipping the unit back to the factory for such a change is not an option due to the time and cost involved.

    Would it be possible to order such modules, including sufficient documentation with instructions, enabling our technicians/electricians to make this adaption between our different missions?

    I have no problem that any such field work would be completely under the users own responsibility and void any warranty that may exist for the unit.


    Thanks for your continued support.

    No, this modification work is relatively complicated. We do Not think your electrician can handle such a job.

    It not only requires replacing the module and circuit board, but also modifying the internal wiring. After completion, it also needs to be tested.

    Therefore, if you can use a three-phase 220V input voltage, then we recommend that you do not modify it; and if you want a three-phase 380V input voltage version, we recommend that you purchase a new converter. You can't just modify the wiring to require a converter to be compatible with two input voltages, 220V and 380V. Generally, only one input voltage can be used.
    Change the INPUT voltage
    If it is possible to change the INPUT voltage. Can that be done in the field or do I need to send the unit back to the factory?
    From: Arlild | Date: 16/10/2023
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Since the converter you bought has a three-phase 220V input voltage, if it is replaced with a three-phase 380V input power supply, the internal circuit modules also need to be changed. So in this case you need to send the converter back to our factory for modification.
    Frequency and voltage
    I brought a 2T flake ice machine from US to Africa. The machine is 220V/60hz and has 20.2kw.
    How to use and protect this one with 220V/50hz local supply power ?
    From: Marcel | Date: 14/10/2023
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Because your machine has a high starting power, we recommend using a 100kW specification inverter power supply, our equipment can convert 220V 50Hz to 220V 60Hz.
    Some questions about frequency converter
    We need your guidance and confirmation on disconnecting the V-Phase in lieu of receiving the replacement capacitors.  
    Because the parts are being sent on regular international freight and are probably being bumped for priority freight.  
    We cannot get a definite date on when we will get the part and we need to get operational ASAP.  
    Can we disconnect the V-Phase to allow us continued functionality of the W
    From: jennie | Date: 19/07/2023
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Before replacing parts of the converter, disconnect the input power and discharge the 6800UF electrolytic capacitor. The capacitor can be quickly discharged by ordinary inclined bulbs or (≥20W 500 ohms) resistors.
    If there is no such thing, please stop the converter for 20-30 minutes, and then use the dc voltage range of the multimeter to measure whether the capacitive voltage is ≤ 5V, and then you can start the replacement parts for security.
    Converter does not have adequate Hz and voltage
    Attached are some pictures I took of the converter. Unit label and circuit board with the unit running.  Pictures of the three panel (3) displays showing all three legs.  
    The U & W leg are working properly but as you can see on the V-leg that it does not have adequate Hz and voltage. I have problems compressing my video to email to you. I will continue to work on compressing it and will forward once I am able.

    Thank you for the photo feedback. We think that this situation should be that the feedback capacitor of the V phase is damaged.
    Please follow the instructions in the attached document to measure the feedback capacitance of V-phase and feed back the measurement results to us, so that we can proceed to the next step.
    Look forward to your reply.
    Some problems with this frequency converter
    I'm still unable to send the video (a filter blocking video sent by email), but here is an extract from the video, a few frames as still photos with comments. Phase U is still active, but phases V and W are shut down.

    We also need to confirm:
    1. Please try to use the previous load to check whether the machine can work normally.
    2. Please replace other loads. We think that there is an alarm on the V and W phases of the machine, which may be a short circuit at the load end, or the machine is overloaded.
    3. Please provide the load information after replacement to facilitate our further analysis.
    Please send us the video via wetransfer.com again.
    Questions about frequency converters
    What sag appears on the voltage if 30kVA load is applied at the peak of the cycle at 220V and 50Hz on frequency converter output?
    From: Keriahaites | Date: 16/01/2022
    Was this review helpful? Yes No (0/0)
    ATO Responded
    As long as the frequency converter is not overloaded, the voltage drops will be less than 3v for less than 50ms.

    I am interested in your frequency converter
    I'm interested in the HZ-50-3310 frequency converter, and I would like to know if I can work in 115v 400hz triphase correctly, because of the specifications of how output voltage I see 110v.
    From: Aschen | Date: 29/09/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Yes, of course the converter output can be 3-phase, 115V, 400Hz. Actually converter output voltage can be adjusted (0-260V) & (40-499.9Hz).
    Frequency converter performance
    We have another project coming up that will be sent to Europe. I don't think testing at 50hz will be an absolute requirement, but I would prefer it.
    The main motor will be run from a VFD, and the entire system should draw less than 5 KVA at 230v, 3 phase, 50hz.
    It looks like the 10 KVA 400hz converter we got from you can also do 50 or 60 hz outputs. Would it still be capable of the full rated line amperage and voltage at these low frequencies?
    From: Johnty | Date: 15/09/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Yes, the converter will be capable of providing its output rated voltage and current at such low frequencies. As long as your load frequency requirement is in the range (40-499.9Hz), everything will be okay.
    Application areas of frequency converter
