The 162H28 is a 20VA low-voltage PCB-mount isolation transformer designed for power management and industrial applications. It features a dual primary of 115/230V and operates on 50/60Hz. The transformer has a split bobbin design with non-concentrically wound secondary windings, requiring all windings to be utilized. It provides a 28V center-tapped secondary at 0.7A in series or 14V at 1.4A in parallel (RMS). The device offers low primary-to-secondary coupling, high insulation with a dielectric strength of 2500Vrms, and Class-B insulation rated at 130°C.
