QP-X Combined transducer

This three phase type transducer it adopts microcontroller technology as the core using the latest algorithms to achieve precise measurement. QP-X series transducer converts an ac voltage input into a load independent output signal. Excellent temperature characteristic and good working stability.

The output signal is based on the a root mean square(rms) measurement of the input signal and hence the transducer can be used with distorted waveforms.
