Product Description

 

The Voltage sensor converts an ac / dc voltage or current input into a load independent output signal. It has excellent temperature characteristic and good working stability. The output signal is based on the root mean square(RMS) measurement of the input signal and hence the transducer can be used with distorted waveforms. The unit conforms to IEC 60688. In addition, the voltage transducer rs485 meets the insulation requirements of IEC 60255-5, clauses 5, 6 and 8 as well as the high frequency disturbance test of IEC 60255-22 for Class III test voltage.

 

Compared with the past transducers, the QPV ac voltage transducer, made of new technologies and materials, have been greatly improved in circuit, process, structure, etc., making its measurement accuracy higher and work more stable.
