Overview
The Signal Transformer DPC-10-90 Class B-3 is a miniature laminated core power transformer designed for industrial control, instrumentation, and general-purpose power supply applications. This model features dual primary configurations (115V/230V parallel) and dual secondary windings (5V parallel or 10V series), making it versatile for various input voltage requirements. The 1VA power rating and compact through-hole PCB mounting make it suitable for control panels, alarm systems, and low-power industrial equipment.
