  1 ACR Series Network Power Meter Overview

  ACR network power meters are designed for power monitoring needs of power systems, industrial and mining enterprises, public facilities, and intelligent buildings. It can measure all common power parameters, such as three-phase current, voltage, active power, reactive power, power, harmonics and so on. Because the power meter also has a perfect communication networking function, we call it a network power meter. It is ideal for real-time power monitoring systems.

  The watch has a high performance-price ratio and can directly replace conventional power transmitters and measuring instruments. As an advanced intelligent and digital front-end acquisition component, this series of network instruments has been widely used in various control systems, SCADA systems and energy management systems.

  2 ACR Series Network Power Meter Product Description

  2.1 Features

  ACREL has years of experience in the design of power measurement products, using modern microprocessor technology and AC sampling technology to design the series of network power meters. The product is designed with cost efficiency, intelligence and reliability in mind, with the following features:

  ● It can directly access signals from current and voltage transformers;

  ● PT/CT ratio can be set arbitrarily;

  ● The meter display can be scrolled;

  ●I/O switch quantity, relay alarm output, 4~20mA analog quantity and other functional modular design;

  ● Multiple instruments can set different addresses;

  ● It can be connected to SCADA and PLC systems; it can communicate with various software in the industry (Intouch, Fix, Citec, configuration network, etc.);

  ● LED or blue screen backlit LCD display, high visibility;

  ●Easy to install, simple wiring and small amount of engineering;

  ● The instrument adopts a special power-off protection circuit. In the case of power loss, the data is not saved. After the power is restored, the instrument continues to run.

  ● Four-quadrant energy metering, time-sharing billing, maximum demand record and 12-month energy statistics.

  2.2 Application

  This series of network power meters has a wide range of applications and system integration. Wherever there is power supply, they have their place of use. It is characterized by high requirements for power quality and power safety and occasions with automation needs. . It is suitable for the following fields and has many successful application experiences.

  ●Energy management system

  ●Substation automation

  ● Distribution network automation

  ●Cell power monitoring

  ●Industrial automation

  ●Intelligent building

  ●Intelligent switchboard, switchgear

  2.3 Features

  ACREL has years of professional experience and has introduced network power meters. It is designed using modern microprocessor technology and AC sampling technology. Each meter can measure a variety of parameters as a front end for the Remote Monitoring System (SCADA); it can be used online or separately.

  The network power meter adopts asynchronous half-duplex RS485 communication interface and MODBUS-RTU communication protocol. Some instruments can also support Profibus-DP protocol to meet your automation communication system. It can be constructed with low-cost shielded twisted pair wiring. A reliable communication network. The high-brightness LED display will provide you with clear data display, whether it is under faint illumination or completely dark.

  For the user of the network power meter, the four-button operation method of the machine can be easily learned in a short time, and the power meter provides a multi-window display function, which allows the user to read a plurality of power parameters at the same time.
