Short-circuit proof PCB transformer
AVB
General Data
Rated input voltage 2 x 115 Vac
Rated output voltage 6 - 2 x 24 Vac
Rated power 0.35 - 3.2 VA
Insulation class B
Maximum ambient temperature 70 °C (AVB 3,2 max. 50 °C)
Efficiency up to 59 %
Degree of protection IP 00
Advantages
Minimum size at high output
Inherently short-circuit proof
Dual input voltage for series or parallel connection
Also with dual 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
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.
