The dimension of the Control Transformer Usage &Toroidal Coil Structure step-up auto-transformator 380V to 200V
The Partial List of GW-B Series Toroidal Transformers with Cable and Mounting Holes:
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'.
We have abtained CE CQC RoHs UL ISO9001:2015,SGS and IEC approval. We guarantee quality is the first.
