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.

No. Our power supply units are designed for indoor use and cannot provide waterproof models.
20KVA frequency converter
Can the input of this device accept 50 or 60Hz? What is the input voltage range for this device with the above options? For example, does this device accept three phase, 0 to 400V? or is the maximum voltage higher?
From: Mason | Date: 06/11/2023

ATO Responded
1. Yes, the input of this frequency converter can accept 50 or 60Hz, No problem.
2. If the input voltage is 400V, then the input voltage range is three-phase 400V±10%.
Questions about frequency converters.
Please may know if you have 10000 watts voltage converter to power my house in Ghana because I am planning all my appliances are 110v/60HZ and Ghana's current is 230V/50HZ.
From: Lizzie | Date: 06/01/2022

ATO Responded
Yes, we have such a converter that can convert Ghana supply (230V, 50Hz) to 110V, 60Hz, so you can run all your appliances.
1. May you list all your appliances individually, and the power capacity or amperage for each appliance, so can you recommend the most suited converter model?
2. Will you run all your appliances at the same time or maybe be 50% or 60% of them at a time?
