Short circuit proof PCB transformer, safety isolating transformer
AVB 3,2/2/9
Characteristics
General data
The PCB transformers of the AVB series feature dual input coils for series or parallel connection and are specifically designed for operation at high ambient temperatures. Thanks to the unique XtraDenseFill resin encapsulation process, the transformers provide permanent corrosion protection, high insulation value, and maximum electrical conductivity.
Benefits
› Safety isolating transformer according to EN (IEC) 61558-2-6
› Minimal size with high performance
› With dual output coils for series or parallel connection
› Absolutely short-circuit proof
› Self-extinguishing encapsulation and hood material
