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

6.Note
The above-mentioned toroidal transformer is frequently-used, we can also manufacture the products by customer design. And the specification is for reference, if has the change further, please take the material object as the standard.
7.GREWIN'S Dimension :External diameter: 55mm-300mm, height :13mm-130mm, Efficiency: 75-98%
we can design the appropriate products according to customers' requirments such as installation dimension, input and output voltage,power...etc.)
B.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.

3.GREWIN has various kinds of state-of-the-art equipment, which are used in production, sampling and testing. Our equipments enable us to produce good quality products efficiently.
