Industrial 3545 PAN7 AC Expanded Scale Voltage Transducer

The 3545PAN7A4 AC Expanded-Scale Voltage Transducer from Scientific Columbus (AMETEK) converts 100–130 V AC input into a standardized 4–20 mA signal for process instrumentation. It is part of the PAN7 family and includes internal auxiliary power, enabling a self-contained measurement signal without an external supply. The unit is designed for industrial voltage monitoring in electrical panels, switchgear, motor control centers, and automation cabinets, providing a reliable signal that can be read by PLCs, data loggers, or control systems. With expanded-scale capability, the 3545PAN7A4 covers a wide voltage range while delivering a proportional current output that facilitates remote sensing and integration in distributed measurement architectures. The 3545PAN7A4 variant specifies 100–130 V AC input and 4–20 mA output, aligning with common industrial voltage-sensing requirements.
