Demonstration Transformer

With one mains coil 230 to 240 V, 50 Hz, 2400 turns and two interchangeable secondry coils, 65 and 130 turns giving outputs of 6 and 12 V approximately at 2A maximum.

The laminated iron core is in two sections, ‘T’ and ‘U’ with butt joints, the stem of the ‘T’ having a cross section 24x24 mm.

A simple channel and wing-nut clamping arrangement facilitates quick assembly and interchange of cols. The coils are would on insulating bobbin, with 2-pins connection for mains and 4 mm sockets for the secondary outputs. The number of  turns, voltage and amperage is marked on each coil. The transformer is supplied complete with 2 m f flex and a 2-pin mains connector.

Overall dimensions 150x100x130 mm.
