DU80E series single-phase electrical parameter measuring instrument

Instrument AC sampling technology, capable of measuring grid voltage, through the instrument panel button set magnification and high cost. With easy installation, wiring is simple, easy maintenance, engineering, field programmable set of input parameters and other characteristics, and can be completed with industry PLC, industrial computer group network communication. Implement intelligent management of enterprises and institutions provide the basis for electrical energy-saving special audit. Digital display table for the power grid, automatic control system, the main measure various electrical grid parameters, such as current, voltage, frequency, power factor, active power, reactive power, etc., in accordance with its additional functionality division, we have X , K, D, S four series digital meters. X series intelligent digital instrumentation, mainly grid current, voltage, power, frequency, power factor and other electrical parameters measurement and display, with intuitive display, high accuracy, good stability, resistance to vibration, etc., AC RMS measurement; it can be used to place severe waveform distortion. K series intelligent digital instrumentation is to increase the ratio function keyboard can be set, with optional RS-485 communication interface output all the way (using Modbus-RTU protocol) to facilitate the networking of digital meters in the X series basis. D series of digital transmission form is based on the X Series adds analog transmit output (4-20mA, etc.) and all the way RS-485 communication interface (using the Modbus-RTU protocol), and can be directly or single-row digital display row digital switching. S series digital alarm monitoring and control instruments is based on X-Series adds relay output function (to achieve "more alarm or remote control function"): with RS-485 digital interface standard Modbus-RTU protocol "telemetry" function, ratio and communication parameters can be set through the instrument panel buttons, the use of flexible Guangzhou, Shenzhen, Zhuhai, Dongguan, Guangdong, Henan, Hebei and Jiangsu 山东 山西 Xinjiang River in Jiangxi
