Remark:

 

A. D refers to the volume of a corresponding transformer, which will be replaced with a digit. 

For the transformer with a single winding, the corresponding max. volume can be reached; for the transformer with two or more windings, the corresponding volume will be reduced

 properly.

 

B. Being a tendency of future pin transformer, it is  applied  with our best self-made 

toroidal core (Po≤0.9W/Kg) in the result of High Efficiency, Low Power Loss and Low

 Temperature-rise to be Green, Energy-saving & Environment-friendly.

 

C. Attributed to our Patent Technology, excluding the pins distribution mentioned above,

 the pins distribution can be freely adjusted by following customer's advice.

 

D. Nice Appearance, Small Size, Moisture Proof & Mould Prevention.

 

E. Pins Quantity can be reduced or increased based on your requirement.

 

3.Material Advantages:
1.100% copper wire made
2.Toroidal style
3.plastic cover :ABS fire Material of withstand high temperatures
4.Epoxy resin
4.high performance insulation
5.Anti-corrosion, waterproof performance
Main parameters:
Input Voltage:AC 220V   230v 110v (Define the voltage)
Output voltage:AC 12V / 24V       (Define the voltage)
Power range:8VA-30VA PCB Toroidal Transformer

 

4.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 

Transformers ,plz kindly check attached file:

D.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.)

E.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.

 

F.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.
