100kVA 3-Phase 380v 50Hz/460v 60Hz Frequency Converter

Thanks for the update. The fuse and IGBT module seem to be normal, the driver board and contactor seem to be abnormal, but we still want to confirm when you measure the AC voltage and DC voltage of the driver board, is the converter powered on? Have you pressed the green start button to run the converter? Please confirm. Because when measuring the driver board, you must press the green start button switch to start the machine. The same goes for the contactor, you have to press the green push button switch to start operation, and then you can operate the knife switch (0-150V/ 0-300V) next to the output circuit breaker. You need to toggle the switch back and forth and then check if the contactor is closing properly.

At first, please do not worry, as the problem will be solved. Just keep answering our inquires accurately.
1. 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. You can send us the large video file via wetransfer.com.
2. Measure the converter output voltage at no load, applied on its terminals via external multi-meter, and feedback measurements to us.
3. Please send a picture of the nameplate label of our converter and the specific specifications of the connected load (such as total load power, rated voltage and maximum current) to our email address support@ato.com.

1. First of all, the maximum output current of this 10KVA converter is only 27A. So the ""200V@400Hz while under load of 200A."" you mentioned below is the wrong number. It should be 20A, right?

2. Now, please remove the load connection, then run the converter with no load, use a multimeter to measure the phase voltages (U-N, V-N, W-N) of the output terminals and feedback the measurement results to us.

3. After completing step 2, you can measure the feedback capacitance of V-phase and W-phase according to the attached troubleshooting document and feedback the measurement results to us.

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.

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.

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.

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.

Yes, our frequency converter will convert 240V, 50Hz (supply) to 120V, 60Hz (load) perfectly.
In your case, recommend the converter model: HZ-60-500W.

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.

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.

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.
