The PT120PC is a PC-mount potential transformer designed to convert 120V AC primary input to a 0-5V secondary output for measurement and control applications. It operates at 50/60 Hz line frequency with 1.0% accuracy on both primary and secondary windings, providing reliable voltage transformation for data acquisition and instrumentation systems. The transformer features a compact PC-mount design with precision-machined pins (0.025 inch square) and dimensional specifications optimized for circuit board integration. The secondary winding offers multiple tap points (pins 6-10) for flexible output configuration, making it suitable for industrial control systems, power monitoring equipment, and precision measurement applications where accurate voltage scaling is required.
