1 Transformers PCB transformers Short-circuit proof PCB transformer AVB BLOCK Website General Data 1.1 1.2 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 % 1.3 Degree of protection IP 00 Advantages 2.1 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 2.2 Self-extinguishing potting and hood material Applications As a mains transformer for adjustment of the voltage and simple electrical isolation. 3.1 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.
