Yokogawa Juxta 246951-540-AHF-1-0 JAU Watt Transformer 200 W 120VAC 5 Amp Input 246951540AHF10

Description:

The Yokogawa Juxta 246951-540-AHF-1-0 JAU Watt Transducer is used in industrial power monitoring systems for converting real power (watts) into a proportional analog DC output signal. Commonly installed in switchboards, control panels, and energy monitoring systems requiring accurate measurement of electrical power consumption. Maintenance teams, OEMs, and system integrators use this part for transducer replacement, energy monitoring upgrades, and integration with PLC, DCS, or SCADA systems.

Applications:

The Yokogawa 246951-540-AHF-1-0 is used in industrial electrical systems where real-time watt measurement is required. It is typically connected to current transformers (CTs) and potential transformers (PTs) to measure power consumption in motors, generators, and distribution systems. The transducer converts measured watt values into standardized analog outputs, enabling monitoring, control, and energy management in manufacturing plants, utilities, and process industries.
