3-Phase Cross-functional Electrical Transducer
www.ce-transducer.com
A. Overview
The transducer has multifunction including electric parameters acquisition, detecting switching value, control and
transducing. It can measure almost all parameters of 3-phase 4-wire circuit including voltage, current, frequency, active
power, reactive power, power factor, accumulated energy consumption and switching value. It adopts all-digital sampling
technology and features high accuracy, good stability and high communication speed. Its complete electric isolation
design makes strong noise-proof ability. It accepts current, voltage and/or switching value input and has some optional
outputs including standard RS-485/RS232 digital port, relay and/or pulse switching value output. These outputs ensure the
transducer can be easily connected to computer system and network. Also it can output an analog value and you can select
any one of parameters to be the analog output.
