Short circuit proof PCB transformer, safety isolating transformer
PT 22/2/8 - Discontinued types – not for new designs
Characteristics
General data
The PCB transformers of the PT series are equipped with an integrated overload protection via a PTC in the input and feature an additional screw fastening in the base plate for space-saving installation. The unique XtraDenseFill resin encapsulation process provides the transformers with 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
› Self-extinguishing encapsulation material
