Product Description
Product Overview
The Signal 241 Series 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 applications from 2.4 VA to 100 VA, these transformers offer single or dual primary configurations (115 V or 115/230 V, 50/60 Hz) and a single center-tapped secondary. They are suitable for various industrial and electronic applications requiring reliable power conversion.
