Detailed Product Description: | Zhejiang NW4E-2S4 NW4E-9S4 reliable quality, best-selling NW4E-2S4 NW4E-9S4 NW4E-9S4K NW4E-2S7 NW4E-9S7 NW4E-2S9 NW4E-9S9 NW4E-9S9A NW4E-9S9B NW4Z-2S4 NW4Z-2S4K NW4E series is a kind of measurement can edit, display, digital communication and power transmission pulse output and other features of multi-functional smart meters, able to complete the power measurement, power measurement, data display, acquisition and transmission, can be widely used in substations automation, distribution automation, intelligent building, the internal energy measurement, management and assessment. Measurement accuracy of 0.5 to achieve the LTD-site and remote display digital interface RS-485 communication, using MODBUS-RTU communication protocol. NW4E-2S4 / NW4E-9S4: measuring three-phase voltage, phase current, active power, reactive power, power factor, frequency, active energy (absorption), reactive power (inductive), through switching means row 4 and 3 LED indicator to show the power and the parameters. Namely: "←", "→" key to switch the meter can display three-phase voltage, phase current, active power, reactive power, power factor, active power, reactive power, frequency, corresponding indicator light is effective. Active power and reactive power 8-digit LED display shows the first row shows "Ep" (active energy absorption) or "Eq" (inductive reactive power), the next two rows of display energy data. NW4E-9S4K: by switching mode and three rows of four LED indicators to measure and display three phase voltage, phase current, active power, reactive power, power factor, the external switch status, frequency, active energy (absorption) and no reactive energy (inductive). The other with 4-way switch input (dry electrical resistance switching signal) and one analog output. When the external switch is connected, the meter section of code in the corresponding position display 1; when the external switch is off, the display is 0. NW4E-2S7/NW4E-9S7: Four-quadrant power measurement: active energy (absorption and release), reactive energy (inductive and capacitive). With 3 rows of 4 LED display, the factory default setting displays active energy absorption (Ep). When the key switch is pressed continuously "→", the instrument will show the inductive reactive energy (Eq), active energy release (Ep-) and capacitive reactive energy (Eq-). 5 seconds without key recovery instrument displays active energy absorption (Ep). NW4E-2S9: three-phase current and active energy measurement, using three rows of three-phase current 4-digit LED display, a row of six LED display active energy. Note: The input signal must be connected to the input voltage when the voltage is not able to connect even when the current meter will show zero, while electricity can not be accumulated. NW4E-9S9/NW4E-9S9A/NW4E-9S9B: 9S9: three-phase current and active energy measurement, with 3 rows of 4-digit LED display. Press the toggle key "→" to display current and active power, active energy, when the first row shows the LED display "Eq", second and third row shows the level of active energy value. 9S9A: measured phase current and reactive power, with 3 rows of 4-digit LED display. Press the toggle key "→" to switch display current and reactive power. Shows the reactive power, the first row of LED display "Eq", the second and third row shows the value of high and low reactive power. 9S9B: measuring three-phase current, phase voltage and active power, use 3 rows of 4-digit LED display. Press the toggle key "→" to switch display current, voltage and active power. Show active energy, the first row of LED display "Eq", second and third row shows the status of active high-energy value. I. Overview NW4Z Network Power Meter is a kind of programmable measurement, display, digital communications and multi-output functions in one instrument of power. Through the power grid voltage, AC current loop sampling, after computing processing power to achieve the three-phase voltage, phase current, active power, reactive power, power factor, frequency, and high-precision four-quadrant power measurement and display ; instruments with a variety of expansion modules: digital communication module, digital switching modules, power modules, and analog pulse output modules can be flexibly chosen. RS485 digital interface allows network communication instrument cluster features; 2-way power pulse output and four analog (4 ~ 20mA) output enables the transmission of electricity and power output; 4 digital inputs and 4-way switch output function that enables local or remote clinical monitoring and control switch signal output ("tele" and "remote control" function). NW4Z network has a very high performance and low cost power meter, you can directly replace conventional power transmitter, measuring gauge meter, energy metering instruments and related ancillary units. As an advanced intelligent digital front-end set of components of the grid, NW4Z series of grid electricity meter has been widely used in various control systems, SCADA systems and energy management systems, substation automation, distribution automation, power monitoring residential, industrial automation, intelligent building, smart power distribution panel, switch cabinet, with easy installation, simple wiring, maintenance, engineering, a small amount of field-programmable set the input parameters, to complete the industry's different PLC, industrial control computer network communications software. NW4Z-2S4: Measuring three-phase voltage, phase current, active power, reactive power, power factor, frequency, active and reactive power by switching mode and three rows of four LED and light display. Optional switching modules: input switch status monitoring and remote, programmable alarm switch output or remote control switch output. Optional analog module: 4 ~ 20mA output can be programmed to achieve the conventional transmitter functions. NW4Z-2S4K: Measuring three-phase voltage, phase current, active power, reactive power, power factor, frequency, active and reactive power by switching mode and three rows of four LED and light display. Switch input monitoring: simultaneous detection of 16-channel switch input state can be telemetry display output. |
