Specifications Toroidal Transformer used for UPS have small size,high efficiency,light weight and low temperature rise.

        A. 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.)
