Product Description

Toroidal Power Transformer for AmplifiersA.

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.
