Low profile transformer

FL

General Data

Rated input voltage 2 x 115 Vac

Rated output voltage 2 x 5 - 2 x 24 Vac

Rated power 2 - 52 VA

Insulation class E

Maximum ambient temperature 40 °C

Efficiency up to 81 %

Degree of protection IP 00

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.
