Block AVB3, 2/2/24 Catalog Page

Mains transformer

AVB 3,2/2/24

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 XtraDenseFill 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.
