Under no circumstances should both ends of the fixing bolt
simultaneously contact the metal chassis or framework as this would
create a potentially dangerous 'shorted-turn'.
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.

we can design the appropriate products according to customers'
requirments such as installation dimension, input and output
8.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
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
GREWIN has various kinds of state-of-the-art equipment, which are
