Block FL42/15 Catalog Page

Safety isolating transformer

FL 42/15

Advantages

Minimum size at high output

Low height

Dual input voltage for series or parallel connection

Dual 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

Applications

As a mains transformer for adjustment of the voltage and simple electrical
isolation.

As an isolating transformer for the safe electrical isolation of the input and
output sides. The transformer may be used to set up protective separation as a
protective measure in accordance with VDE 0100.

As a safety isolating 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.
