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

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.
