DPA Power Transducer
Inquire NowDescription
The DPA Power Transducer is a highly advanced device designed to convert AC/DC voltage or current inputs into a load-independent output signal. Featuring exceptional temperature characteristics and remarkable stability, this transducer utilizes root mean square (RMS) measurement to accurately process distorted waveforms. Meeting the standards of IEC 60688, it also complies with insulation requirements outlined in IEC 60255-5 and successfully passes high-frequency disturbance tests per IEC 60255-22 for Class III test voltage.
With enhancements in circuit design, materials, and structure, the DPA Power Transducer offers significantly improved measurement accuracy and stability compared to earlier models. It is an ideal solution for various applications, including medium and low voltage systems, ensuring reliable metering of distribution feeders, transformers, and motors.
