Product Description
Product Overview
Signal's 241 Series Two-4-One Power Transformers are designed for chassis mounting and feature a split bobbin construction that provides superior isolation and low capacitive coupling. These transformers are suitable for a wide range of power applications, from 2.4 VA to 100 VA, offering single or dual primary configurations (115 V or 115/230 V) and single center-tapped secondary outputs. They are built with Class B insulation (130 C) and utilize solder lug/quick connect terminals for easy integration.
