Product description
Main feature
● EDA9033E series module is an upgraded replacement of EDA9033A module, adding four-quadrant active and reactive power measurement, frequency measurement, positive and negative active and reactive power measurement, and display driver interface。
● EDA9033E module is an intelligent three-phase electric parameter data comprehensive acquisition module.The three-meter method is used to accurately measure the three phase current, three phase voltage (true RMS), active power, reactive power, power factor, frequency, positive and negative active power, positive and negative reactive power in three-phase three-wire or three-phase four-wire AC circuits。
● Its input is three-phase voltage (0 ~ 500V), three-phase current (0 ~ 1000A);The digital signal output is RS-485 or RS-232 interface, which can be widely used in various industrial control and measurement systems and various distributed/distributed power monitoring systems。
● Replacing a series of transmitters, such as current, voltage, power, power factor, electricity, etc., and measuring the standard output signal of these transmitters can greatly reduce the cost of the system, facilitate the field wiring, and improve the reliability of the system。
