Digital Multifunction Panel Meter (PD76-24E-WFF)

Product Description

PD76-24E-WFF Digital indicating Panel Mounted Electrical Measuring Instrument is designed for the electrical monitoring for utilities, industrial mining corporations, intelligence towers and communities. It adopts large scale IC, digital sampling technology and SMT technology. It can measure all the common electrical parameters with high accuracy, such as three-phase voltage, three-phase current, active power, reactive power, frequency, power factor, active energy, reactive energy and four quadrant energy. It is capable of multi-tariff function (10 time segments, 4 rates). The durable LCD displays the parameters measured and the performance information of electrical network system. With high speed RS485 communication port and conformance to the Modbus protocol. There are four programming pushbuttons in the faceplate, it is very convenient for users to achieve switching display and meter's parameters program setup at site, with high flexibility.

There are many extended functions to choose, for instance, the function of 4 analog(0-20mA/4-20mA )output is for energy and electricity transportation output, and the function of 4 switching input and output is for local or remote switching signal monitoring and control output ( "remote communication"and "remote control"function).
PD76-24E-WFF with excellent performance and reasonable price, it can replace the normal electricity transportation instrument, measurement indicating meter, energy measuring meter and other related accessorial units.
PD76-24E-WFF can be used widely for energy management system, transformer substation automatization, switching network automatization, industrial automatization, intelligence buildings, intelligence switchboards and switch cabinets, it is characteristic of convenient installation, simple wiring, easy maintenance, and less works. It also can be connected with PLC and industry control computers.
