It can measure all common power parameters, such as the three-phase current, voltage, power, electricity, etc., due to the Power Meter also has a perfect communication networking capabilities, it is very suitable for real-time power monitoring system. 1.1 Model Description ■ Features With years of power measurement experience in product design, the modern monolithic micro-processing technology, and dedicated energy measurement technology design and became the series Multifunction Power Meter. The design of the product is fully taken into account the cost-performance ratio, ease of use and reliability, has the following features: ☆ direct access signal from the current and voltage transformers; ☆ freely set the PT / CT ratio; ☆ instrument can be fixed also scrollable display; ☆ multi-block instrument can be set to a different address; ☆ light-emitting diode display, highly visible; ☆ convenient to install, simple wiring, a small amount of engineering; ☆ instrument using a dedicated power-down protection circuit, power-down case, energy not lost after the power is restored, the energy to continue to take the word of. ■ application of the series of instruments very wide range of applications and easy system integration, all electricity supply places have them handy, especially for power quality, electrical safety requirements of the occasion as well as the automation needs of occasions. It applies to the following areas, and there are many successful applications experience: ☆ energy management systems; ☆ substation automation; ☆ distribution automation; ☆ residential electricity monitoring; ☆ industrial automation; ☆ intelligent building; ☆ intelligent distribution panels, switchgear. ■ The function of each instrument can measure a variety of parameters, as the front end of the remote monitoring system can be networked to use, and can also be used alone. Series Multifunction Power Meter with half-duplex RS485 communication interface and Modbus-RTU communication protocol to meet your automation communication systems, the use of low-cost shielded twisted pair can construct a reliable communications network. In the faint illumination, or completely dark, high-brightness light-emitting LED display will provide you with a clear data display. For the Series Multifunction Power Meter users can easily learn in a short period of time the machine four keyboard operation of law, the Power Meter offers multi-window display function allows the user to read a number of power parameters. ■ General technical measurement: U, I, P, Q, S, PF, Hz, three-phase power network power parameter measurement: active, reactive energy measurement: programmable LED switch, cycle way, 3 rows of 4 bit LED. Output: RS-485 communication interface, MUDBUS-RTU protocol may network telecommunication. Energy pulse output: 2-way, 1-way active energy output, 1 channel reactive energy output. Digital input module (optional configuration): the state of the switch input monitoring and remote communication, programmable alarm switch input or remote switching output. Analogue sent to the module (optional configuration): Programmable 0 ~ 20mA / 4 ~ 20mA output, traditional transmitter function. Apply to the mains, complete detection and management of large capacity with loop electrical parameters. On instrument specific shape, openings, wiring diagrams and technical information such as call to obtain; through the State Administration of Quality Supervision, Inspection and qualified.
