Category: transformerDescription: VB The PT series 230V AC 50 to 60Hz primary winding, single or double secondary winding, is used for series or parallel connection (for safety compliance reasons, transformers with 2 x 15 and 2 x 18V outputs, 0.35 to 3.2VA, and all transformers with 2 x 24V outputs should not have their secondary windings connected in series, as this means they will not comply with VDE 0550 certification). The VB series (0.35-3.2VA) has inherent short-circuit protection. The PT series (4.5-22VA) is protected by internal PTC equipment with a compact design vacuum epoxy resin molding, achieving UL94-V0 level dual load glass fiber reinforced polyamide wire spools with 100% electrical and insulation testing, high efficiency and low temperature rise, low capacitance between windings, and low radiation noise.
