Overview

S3 (T) - WHD.S3-WHD, N3-WHD active energy transmitter is a type of active energy transmitter that measures the active energy of a system by separately collecting voltage and current signals, and performing high-precision time division multiplier operations. It converts the active energy of the system into a high linear ratio pulse output, which can be voltage pulse type, voltage free pure contact (optocoupler isolation) output, or relay contact output; And there are multiple options for the transmitter's energy constant (number of pulses per kilowatt hour), which facilitates data acquisition.

Overview

S3(T)-WHD. S3-WHD,N3-WHD Type of active electrical energyA transmitter is a device that measures the active electrical energy of a system by separately collecting voltage and current signals and performing high-precision time division multiplier operations. It converts the active electrical energy of the system into a high linear proportional pulse output, which can be voltage pulse type, voltage free pure contact (optocoupler isolation) output, or relay contact output; And there are multiple options for the transmitter's energy constant (number of pulses per kilowatt hour), which facilitates data acquisition. This series of instruments can operate continuously for a long time and is suitable for measuring electrical energy used for automated monitoring in non electric energy billing systems. It is applied to frequencies of50Hzor60HzSingle phase, three-phase three wire(Balanced or unbalanced)Three phase four wire(Balanced or unbalanced)in the circuit,andThe technical indicators of S3 (T) and N3 series active energy comply with the relevant provisions of GB/T15283-99 "0.5, 1, and 2 level AC active energy meters" standard regarding 0.5 level active energy meters.

feature

This series of products has high measurement accuracy, good conversion performance, good temperature characteristics, and lightning protection function. The ability to measure reverse active energyIt has long-distance transmission capability (4~20mA, 500 Ω), fixed in accordance with DIN46277, and can be installed on 35mm aluminum rails.

note① The output range (number of pulses) of the active energy transmitter is calibrated at 1kWh.

② Choose the appropriate output type based on the actual situation of the system, while paying attention to the voltage level

Among them, optocoupler isolation is relatively reliable, but the system must provide matching

Power supply and line current resistance; Relay mode interface is simple, but relay must be considered

The lifespan of the device and the arc during suction. When there is no voltage pure contact output, it should

Pay attention to the positive (C) and negative (E) polarity wiring of the optocoupler output.

③ When measuring the positive and negative electrical energy of the system, the electrical energy signals are output separately.

④ The calibration of system power can be found in the previous active power annotation: item ②.

⑤ If the user requires other special calibrations, please specify the parameter values in the contract.
