Yokogawa 246955-540-AHD-0-0 Three-Phase Watt Transducer

The Yokogawa 246955-540-AHD-0-0 Three-Phase Watt Transducer is a Yokogawa JUXTA Series device that converts three-phase real power into a standardized 4–20 mA analog signal for industrial power monitoring. Typically installed in switchboards, substations, and electrical distribution panels, it interfaces with current transformers (CTs) and potential transformers (PTs) to measure watts and feed PLC, DCS, or SCADA systems for load monitoring and energy management. Key specifications include 120 VAC input, 5 A AC CT input (typical), 60 Hz operation, a 500 W power range, 16 screw-terminal terminals, panel or DIN-rail mounting, and an accuracy of approximately ±0.5% of span. The transducer output is 4–20 mA DC, enabling precise real-power signaling for control and optimization in manufacturing plants and utility environments.
