Two-4-One™ Power Transformers

Signal Transformer/Bel Two-4-One™ Power Transformers use split bobbin construction that provides superior isolation and low capacitive coupling. These transformers offer chassis mounting style, single or dual primary winding, and a single secondary winding.The two-4-one transformers are available in 241 series and 241-L series, where the 241-L transformers offer lead wires. Both the 241 and the 241-L series are UL recognized to UL 506/UL 5085-1, File # E63829 and CSA certified to C22.2 #66.1, File # 221070.
