Product Details

Product description

Overview

E series (42 square) multifunctional power meter (hereinafter referred to as the meter)Specially designed and manufactured for the power monitoring requirements of the power supply and distribution system. It can measure all commonly used electrical parameters with high accuracy, such as three-phase voltage, three-phase current, active power, reactive power, frequency, power factor, four quadrant electrical energy, etc; Long life LED display instruments measure parameters and provide operational information for the power grid system; Equipped with RS485 communication interface and adopting MODBUS_STU communication protocol; The dashboard has four programming buttons, allowing users to easily switch displays and program instrument parameters on site, with strong flexibility.
The instrument has multiple expansion function modules to choose from: 4-channel analog (0-20mA/4-20mA) output can achieve the function of transmitting and outputting electricity; 4-channel switch input and 4-channel switch output can achieve local or remote switch signal monitoring and control output functions ("remote signaling" and "remote control" functions).

Instruments can directly replace conventional power transmitters, measurement indicators, energy meters, and related auxiliary units. With a modular structural design, users can choose the most economical functional configuration according to their actual needs, and have a high performance price ratio.
Instruments can be widely used in energy management systems, power grid automation, residential power monitoring, complete equipment switchgear and other occasions. They have the advantages of easy installation, simple wiring, easy maintenance, small engineering quantity, programmable input parameters on site, and can complete networking with different PLCs and industrial control computer communication software in the industry.
