Hammond Manufacturing 161E28 Low Voltage Power Transformer

The 161E28 is a 1.2VA low voltage PCB-mounted isolation transformer designed for power management and industrial applications. It features a 28V center-tapped secondary at 40mA and a parallel secondary of 14V at 80mA (RMS). The transformer has a 115V primary operating at 60Hz, with a vertical-mount split bobbin design and non-concentrically wound dual windings. It offers low primary-to-secondary coupling without the need for an electrostatic shield, high insulation with a hi-pot rating of 2000Vrms, and a Class-B insulation rating of 130°C.
