Product Description
Product Overview
Signal's 241-L Series Two-4-One Power Transformers are chassis mount units designed for applications requiring superior isolation and low capacitive coupling. Featuring a split bobbin construction, these transformers offer a power range from 2.4 VA to 100 VA and are built with Class B (130C) insulation. They are equipped with UL1015, CSA TEW hook-up lead wires rated for 600V and a temperature range of -40C to +105C, passing the UL VW-1 flame test. All primary and secondary lead wires are 18 AWG and 12 inches in length. These transformers are RoHS compliant and available in custom versions upon request.
