Tips: How to select a 3 phase step up & step down isolation transformer?

1. Confirm the power supply voltage (V) provided by the grid and the required input rated voltage of the electric equipment to determine the voltage (V) ratio of the transformer.
2. Confirm the phase number of the input power supply required by electrical equipment to determine whether to make three-phase or single-phase system transformer.
3. Confirm the required input rated current (A) of the electrical equipment to determine the transformer capacity (KVA).
4. Insulation class requirements: A class 105 ℃, B class 130 ℃, F class 155 ℃, H class 180 ℃.
5. Autotransformer or isolated transformer.
