EN 61558, ENEC 10, UL recognized component. Transformers for PCB mounting, short-circuit proof, VB and PT series. 230V AC 50 to 60Hz primary. One or two secondary windings for series or parallel connection. For conformity reasons, 0.35 to 3.2 VA transformers with 2 x 15 and 2 x 18V outputs and all transformers with 2 x 24V outputs should not have the secondary windings connected in series, otherwise they would not meet VDE 0550 approval. Series VB (0.35-3.2 VA) is inherently short-circuit proof. Series PT (4.5-22 VA) is protected by an internal PTC unit. Compact design with vacuum epoxy resin molded part conforms to class UL94-V0. Two-piece coil of fiberglass-reinforced polyamide. 100% electrical and breakdown testing. High efficiency and low heating. Low inter-turn capacitance. Low noise. Extra mounting points for secure PCB mounting (models 4.5 VA and above).
