Electronic auto toroidal transformer with CE,ROHS approval

Specifications Toroidal Transformer used for home applicance,solar have small size,high efficiency,light weight and low temperature rise

 1.We have abtained VDE.UL.CE.ROHS,ISO9001 etc. Appoval as below:      2.The toroidal transformer  for Home appliance:            3.The operating workers is testing toroidal transformers :         1. Installation: Horizontal (non-conventional-type base plate), sunk, side type, and bridge. 2.Application: Especially low-hum and low-dispersing construction Low-level of induction High-grade design casing possible Statically shield winding and magnetical shield winding optional . 3.Equipment: Over 50 sets toroidal/annular/ ring coil winding machines, 3 EI type transformer lines, 2 sets of vacuum annealing furnaces, A set of nitrogen and hydrogen production equipment. 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.   7.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.)   8.Grewin's Toroidal Transformers in different power:
