Product Description
Product Overview
The Signal 241 Series Two-4-One Power Transformers are chassis-mount transformers designed for applications requiring superior isolation and low capacitive coupling. Featuring a split bobbin construction, these transformers are available in power ratings from 2.4 VA to 100 VA. They are suitable for use with single or dual primaries (115 V or 115/230 V, 50/60 Hz) and offer a single center-tapped secondary. Terminals are of the solder lug / quick connect type, and the insulation is Class B (130 C). Custom versions are available upon request.
