    Ok, and if your equipment is around 100-200W, then recommended frequency converter model: HZ-60-1101, 1kVA power capacity, input: 1ph, 230V (+/- 10%), 50/60Hz and output: 1ph (L ,N,G), adjustable (0-300V), adjustable (40-120Hz), 4.2A.
    ATO recommends the model to me according to my needs
    We need 100kVA converter 380Vac 50HZ (L1,L2,L3, N,G) to 440Vac 60Hz (L1,L2,L3, N,G), we have a 65kW (with VFD), in this case the inrush current is low. What do you recommend?

    Ok, based on your choice, recommended frequency converter model: HZ-50-33100, 100kVA power capacity, input: 3ph, Wye (L1,L2,L3 + N,G), 380V (+/- 10%), 50/ 60Hz and output: 3ph, Wye/Delta (L1,L2,L3 + N,G), adjustable (0-520V), adjustable (40-120Hz), 138.8A.
    Our new requirements for frequency converter
    Revising my request, the minimum frequency of 40 Hz can be modified to 48 Hz
    Considering the performances is the converter equipped with output LOW PASS filter? If yes, could you please deliver a harmonic frequency spectrum of the output waveform?
    The converter output transformer 3 phase is wye connected. could the converter be connected for single phase output switching by a selector the electronics firing control and manually modify the transformer connections?
    The control of frequency and output voltage can be remotely managed by SW control or HW control (potentiometer for example)?
    Please send an update formal offer for two versions 15 and 30 KVA with the same performances 48-120 Hz output 0-520 V to the following address.

    Thanks for your prompt reply. According to your new requirements below, we need you to confirm again and then we will better quote.
    1. We can add a LOW PASS filter to the output end of the converter, but for now we don't have measuring instrument, we cannot provide the output waveform to you.
    2. Yes, the converter output transformer 3 phase is way connected. Our converter can customize the selector to modify the transformer connection manually.
    3. We can remotely manage the frequency (only 2 digits) and output voltage control through software control or hardware control(such as potentiometer). At present, the remote control of our frequency can only reach 2 digits, which means that the output frequency of 48-99 Hz can be controlled remotely, and the frequency above 3 digits 100 Hz is not supported for now. Is that acceptable to you? Or what is the frequency range that you actually use?
    Please kindly confirm the above three points, and then we will offer you a formal quotation.
    I am looking for a frequency converter
    Hi, I am looking for a step-down transformer/ frequency converter. To go from 240v 50Hz to 120v 60Hz. Honestly, it is for some music equipment, a 5 watt amp, a 15 watt amp and a series of guitar pedals. The total power draw is quite low. In total, it is probably less than 50 watts peak.
    These products look like they do exactly what I'd want, but is there anything available that matches my needs?

    ATO Responded
    Yes, our frequency converter will convert 240V, 50Hz (supply) to 120V, 60Hz (load) perfectly.
    In your case, recommend the converter model: HZ-60-500W.
    We have these needs for frequency converter
    We would need product information for a frequency converter with these requirements:
    Input: 440V – 60Hz – 3 phases   GND
    Output: 230V – 50Hz – 1 phase   Neutral   GND
    Peak Amp in output: 55A
    Max continuous Amp in output: 13A

    Yes, based on your specs, recommended frequency converter model: HZ-50-3115, 15kVA power capacity, input: 3ph, Delta (L1, L2, L3 + G), 440V (+/- 10%), 50/60Hz and output: 1ph, (L + N, G), adjustable (0-300V), adjustable (40-120Hz), 62.5A.
    Which frequency converter do you recommend for us to use?
    We need a converter for complete machine supply for press brake. Our press brake total connected load 20kVA.
    Input voltage is 400v 3 Phase and the required frequency is 50Hz. The full load current is 29A.
    So we need the frequency converter to convert from 60Hz to 50Hz with the same 400V.
    The system asks the machine to have hydraulic pumps and servo motors. What do you recommend?

    If your Press Brake has only servo motors with connected drives, then it will Not be expected to see high inrush current of such motors, and in this case, recommended frequency converter model: HZ-50-3345, 45kVA power capacity, input: 3ph, Wye (L1,L2,L3 + N,G), 400V (+/- 10%), 50/60Hz and output: 3ph, Wye/Delta (L1,L2,L3 + N,G), adjustable (0-520V ), adjustable (40-120Hz), 62.5A.
    Does the terminal of the frequency converter have a neutral wire?
    Your frequency converter input terminal or output terminals having neutral line?

    ATO Responded
    For converter input "your supply" configuration, it can be 3-phase, Wye (L1, L2, L3 + N, G) or 3-phase, Delta (L1, L2, L3 + G ). Which one do you need?
    If the neutral is required "Wye", your supply must have this terminal.
    If your supply is 3 phase 4 wire (3 wire for hot conductor, and the fourth one is for neutral), then you have to use 3-phase, Wye (L1, L2, L3 + N, G) converter config.
    The converter output will be (L1, L2, L3 + N, G), and it works for both Delta and Wye configuration. We mean neutral can be used or not. It's up to you.
    We currently own one of your frequency converters.
    Frequency Converter Model HZ-50-33100, 100KVA.
    We are looking at getting this unit serviced and checked. We are based in the UK (London) and was wondering if you had agents here that would be able to service it please.

    Sorry, we don't have an agent repair service elsewhere, and we can only provide technical support via email currently. But please don’t worry, as the problem will be solved. Just keep answering our inquires accurately.
    1. Please describe the fault of this converter to us in detail.
    2. Now, open converter side covers and power on the converter, then take a video showing us the internal main circuit boards, especially the ones with red led indicators and beeping sound, and show us the converter display as well while the converter is running ..
    3. Measure the converter output voltage at no load, applied on its terminals via external multi-meter >>> U, N -SN, -WN, and feedback measurements to us.
    4. If the converter has an alarm sound and the output voltage is abnormal, please measure the fuse, IGBT module, and driver board according to the attached troubleshooting document, and feedback the measurement results to us.
