    Tips: Will 50Hz and 60Hz exchange affect transformer?

    The influence of 50Hz/60Hz to the transformer and mutual inductor is similar to the contactor. The frequency change has no great influence to its performance. But it is mainly reflected in the loss and temperature rise. Therefore, it can be generally used in a certain design tolerance range. In addition, the transformer and mutual inductor of the same capacity designed by 50Hz is bigger than that of 60Hz in size, because satisfying the same voltage grade U≈E=4.44Fnbs, a lower frequency f will magnify the winding number N or increase the effective area S.

    Based on your specs, recommended frequency converter model: HZ-50-1310, 10kVA power capacity, input: 1ph, 230V (+/- 10%), 50/60Hz and output: 3ph, Wye/Delta (L1,L2,L3 + N,G), adjustable (0-260V), adjustable (40-120Hz), 27.6A.
    Suitable frequency converter
    Input voltage will be 400V 3 phase 50Hz Wye
    Output: 400V 3 phase 60Hz
    Load may vary according to projects. We have motors, small cranes, PLC, lights, heaters etc.
    May I know if there is a suitable version that meets the needs of other projects also in general.
    Let us also know the price range.

    I want to ask about the frequency converter
    I took a look at the frequency converter that you provide, but I am not sure if I understand the specs correctly, so to enquire here for your help. I am looking for a 230VAC, 50Hz 1P input to a 115V, 60Hz 1P output of at least 12KW output, and a 400-415VAC, 50Hz 3P Wye input to a 440V, 60Hz 3P DELTA(no neutral) output of at least 18KW. The tricky part for us would be the wye input for 3P that gives DELTA output. Advice, please.

    No problem. As for the converter output, it works for both Wye/Delta configuration (L1, L2, L3 + N, G).
    But for the converter input (your supply), you have to specify whether you need it as Delta (L1, L2, L3 + G) or Wye (L1, L2, L3 + N, G), its free option.
