QP-A/V(T) voltage transducer

QP-A/V(T) voltage transducer

This single type transducer it adpots microcontroller technology as the core using the latest algorithms to achieve precise measurement. QP 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.
