Split Bobbin Two-4-One™ Power Transformers
Signal Transformer's Two-4-One power transformers are constructed in split bobbin winding style
Signal Transformer's Two-4-One power transformers use split bobbin construction which is a method of winding the transformer's primary and secondary, side-by-side on a bobbin with an insulation barrier between the two windings. Split bobbin construction provides superior isolation and low capacitive coupling. These transformers offer chassis mounting style and a single or dual primary winding with a single secondary winding. The Two-4-One transformers are available in 241 series and 241-L series transformers, which offer lead wires, and DP-241 series which is a dual primary 115 VAC / 230 VAC. These transformers meet industry safety standards. The series is recognized to UL 506/UL 5085-1, File # E63829 and CSA certified to C22.2 #66.1, File # 221070.
