This transformer complies with EN 61558 and is an ENEC 10 and UL recognized component. It is designed for PCB mounting, is short-circuit proof, and belongs to the VB and PT series. The primary voltage is 230V AC with a frequency of 50 to 60Hz. It features one or two secondary windings for series or parallel connection. For compliance reasons, 0.35 to 3.2 VA transformers with 2 x 15V and 2 x 18V outputs and all transformers with 2 x 24V outputs should not have the secondary windings connected in series, as they would not meet VDE 0550 approval. The VB series (0.35-3.2 VA) is inherently short-circuit proof, while the PT series (4.5-22 VA) is protected by an internal PTC unit.

The transformer has a compact design and is made of vacuum epoxy resin molded parts that conform to class UL94-V0. It features a two-piece coil of fiberglass-reinforced polyamide, 100% electrical and breakdown testing, high efficiency, low heating, low inter-turn capacitance, and low noise. Additionally, there are extra mounting points for secure PCB mounting on models 4.5 VA and above.
