Transformers 1 PCB transformers Short circuit proof PCB transformer 1.1 AVB BLOCK Website General Data 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) 1.3 Efficiency up to 59 % Degree of protection IP 00 Advantages Minimum size at high output 2.1 Unconditionally short-circuit proof Double input voltage for series or parallel connection Also with double output voltage for series or parallel connection Designed for high ambient temperatures Permanent corrosion protection, high insulation value and maximum 2.2 electrical reliability thanks to XtraDenseFill resin encapsulation Coil shell in 2-chamber technology Self-extinguishing potting and hood material Applications 3.1 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. 3.2 Sample application 3.3 4.0 Standards & 1 Z Approvals W J Z 5.1 Mains transformer UL 5085-1/-2, CSA 22.2 No.66 to: VDE 0570 Teil 2-1, DIN EN 61558-2-1, EN 61558-2-1, IEC 61558-2-1, UL 5085-1/-2, CSA 22.2 No.66 Safety isolating transformer to: VDE 0570 Teil 2-6, DIN EN 61558-2-6, EN 61558-2-6, IEC 61558-2-6, UL 5085-1/-2, CSA 22.2 No.66 5.2 Subject to change 231Transformers 1 PCB transformers Short circuit proof PCB transformer Short circuit proof PCB transformer AVB AVB BLOCK Website Typ AVB 0,35/2/..
