4.Warning 
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'. 
5.Certificate 
The certificate of our transformer has CE CQC RoHs UL 
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.
