DPA AC Power Transducer

The DPA Power Transducer converts both AC and DC voltage or current inputs into a load-independent output signal. It exhibits exceptional temperature characteristics and maintains excellent working stability. The output signal is derived from the root mean square (RMS) measurement of the input signal, allowing the transducer to effectively operate even with distorted waveforms. This unit complies with IEC 60688 standards and meets the insulation requirements outlined in IEC 60255-5, sections 5, 6, and 8. Additionally, it successfully passes the high-frequency disturbance test according to IEC 60255-22 for Class III test voltage.

Compared to previous-generation transducers, the DPA Power Transducer, incorporating cutting-edge technologies and materials, has seen significant improvements in its circuitry, processes, structure, and more. These advancements result in enhanced measurement accuracy and greater operational stability.
