Short circuit proof PCB transformer
AVB 3,2/2/18
Advantages
Minimum size at high output
Unconditionally short-circuit proof
Double input voltage for series or parallel connection
Also with double output voltage for series or parallel connection
Designed for high ambient temperatures
Permanent corrosion protection, high insulation value and maximum
electrical reliability thanks to XtraDensiFill resin encapsulation
Coil shell in 2-chamber technology
Self-extinguishing potting and hood material
Applications
As a mains transformer for adjustment of the voltage and simple electrical
isolation.
As a safety transformer for the safe electrical isolation of the input and output
sides. The transformer is suitable for creating SELV and PELV circuits because
of the limit on the output voltage.
