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. Additional fixing holes are provided to ensure low noise between windings at 4.5V.
