AC Multi-function Transducer(3-phase 4-wire)， BD-4E
AC Multi-function Transducer(3-phase 4-wire)， BD-4E
BD-4E series Electricity Transducer can measure Voltage, Current, Power, Power factor, Frequency; 1.2 times of rated value overload; DC 0-5V/0-10V/0-20mA/4-20mA all can be choosed as analog output.
① Record storage analog output record
② Provide analog output signal to PLC
③ Provide analog output to frequency converter
④ Provide analog output for digital display meter
① The measuring transmitter is designed to convert AC electric signal into analog signal or digital signal in accordance with GB / T 13850
② High accuracy class: 0.5
③ Full electric parameter measurement, freely combined transmission output type
④ The true RMS measurement is suitable for occasions with large harmonics, voltage and current waveform distortion and other harsh environments
⑤ It can be worked with RS485 communication interface and connect on the same 485 bus with the control module of other manufacturers, which is convenient for
computer programming. Users can easily build their own measurement and control system
⑥ It can be worked with external display module, and the customer can directly change the input range and transmission type on site
⑦ Optional transformer built-in perforated installation type, convenient for construction wiring and cost saving
