How to design Transformer ?

 
Transformer capacity is rated in Volt-Amps (VA) which is generally the same as 

wattage (Watts).Most loads are labeled with their proper operational voltage (Volts),

current (Amps), frequency (Hz), and wattage (Watts or VA).

When you need to design a transformer,we must know the mainly below parameters 

to be customized:

GREWIN's Custom Toroidal Transformers 

Dual 110V Power Transformer:

For the international market request, these types of the GREWIN Transformers are designed

into dual primaries for 110V. No matter what about your local voltage is 110V or 220V, you

should use them. Below are the methods for using:
1. If you are using 110VAC(such as Taiwan, US), Please parallel the two primaries 110V. Please

pay attention to the terminals of 110V must be short circuit, and the terminals of 0V must be

short circuit.

2.If you are using 220VAC(such as Hongkong, China Mainland, Europe), Please series the two primaries.  Please pay attention to one terminals of 0V must be short circuit with another

terminals of 110V.
