Product Description
Product Overview
The Signal 241 Series Two-4-One Power Transformers are chassis-mount transformers featuring a split bobbin construction for superior isolation and low capacitive coupling. Designed for a wide range of power requirements from 2.4 VA to 100 VA, these transformers offer robust performance with a dielectric strength of 2500 Vrms Hipot. They are available with single or dual primaries (115 V or 115/230 V, 50/60 Hz) and a single center-tapped secondary. Terminals are of the solder lug/quick connect type, and insulation is Class B (130 C). These transformers are UL recognized and CSA certified, ensuring compliance with industry standards. Custom versions are available upon request.
