Short circuit proof PCB transformer, separating transformer
PT 7,5/2/24 - Discontinued items – not for new applications
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
› Separating transformer according to EN (IEC) 61558-2-1
› Minimal size with high performance
› With dual output coils for series or parallel connection
› Self-extinguishing encapsulation material
