EDA9033F Three phase Integrated Power Monitoring Instrument
Product details
Product Features
EDA9033F measuring instrument is an intelligent three-phase electrical parameter comprehensive acquisition measuring instrument; The three meter method accurately measures and displays electrical parameters such as three-phase voltage, three-phase current (true RMS), active power, reactive power, power factor, frequency, positive and negative active energy, and positive and negative reactive energy in three-phase three wire or three-phase four wire AC circuits on site through LED display. And it comes with 2 switch inputs and 1 adjustable relay alarm output. Its input is three-phase voltage (0-500V) and three-phase current (0-10A); Output digital signals as RS-485 or RS-232 interfaces, supporting communication protocols including MODBUS-RTU standard protocol, MODBUS-ASCII protocol, ASCII code communication protocol, and hexadecimal LC-04 protocol. The EDA9033F measuring instrument can be widely used in various industrial control and measurement systems, as well as various distributed/distributed power monitoring systems.
PRODUCT FUNCTION
Measure and display the three-phase phase voltages Ua, Ub, Uc; Three phase currents Ia, Ib, Ic; Active power P, reactive power Q, power factor PF, frequency f, active power Pa, Pb, Pc of each phase; Reactive power of each phase Qa, Qb, Qc; Positive active energy, reverse active energy, positive reactive energy, reverse reactive energy and other electrical parameters. Three rows of 4-digit LED displays and one row of 8-bit LED displays display various measurement data and setting parameters.
