Product Description
The Voltage sensor converts an AC / DC voltage or current input into a load-independent output signal. It has excellent temperature characteristics 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, has been greatly improved in circuit, process, structure, etc., making its measurement accuracy higher and work more stable.
* 2/0.5 measurement accuracy
* Support customized parameters* RMS measurement and output
* 500ms response time
* 35mm Din rail mounting
* High load capacity and reliability
* Low ripple output * A wide range of both D.C. current and voltage inputs are offered.
