PCB transformer, safety isolating transformer
VR 7,5/1/8 - Discontinued items – not for new applications
Characteristics
Benefits
› Minimum size at high output
› Also with double output voltage for series or parallel connection
› Permanent corrosion protection, high insulation value and maximum electrical reliability thanks to XtraDenseFill resin encapsulation
› Self-extinguishing potting material
› Space saving installation thanks to additional screw mounting in the base plate
