Product Description
Product Overview
The Signal 241 Series Two-4-One Power Transformers are chassis-mount transformers designed with a split bobbin construction for superior isolation and low capacitive coupling. These transformers are suitable for a wide range of applications, offering power ratings from 2.4 VA to 100 VA. They feature single or dual primaries (115 V or 115/230 V) and a single center-tapped secondary, with solder lug/quick connect terminals for easy integration. The insulation is Class B (130 C), and they are UL recognized and CSA certified.
