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.
