ACR10R Rail-type Multi-function Electrical Instrument is an intelligent device designed for comprehensive energy monitoring and power management. It integrates precise measurements of electrical parameters such as single-phase/three-phase current, voltage, active power, reactive power, apparent power, frequency, and power factor, offering real-time data for energy management systems. One of its standout features is support for Ethernet Communication with the Modbus-TCP Protocol, enabling seamless integration into modern industrial automation networks. The instrument can be easily installed on-site using DIN rail mounting and a split-core current transformer, eliminating the need for busbar removal and reducing installation time and labor costs. Its LCD display and intuitive button interface allow users to configure parameters and monitor operations locally, while relay outputs and switch inputs provide remote signaling and control capabilities. Designed for demanding industrial environments, it is ideal for energy-efficient retrofits in high-energy-consumption industries such as smelting, iron and steel production, and semiconductors. Additionally, it supports applications like distributed photovoltaic power monitoring and energy demand management. With a wide operating temperature range and high safety standards, the ACR10R combines reliability, versatility, and ease of use for diverse power monitoring needs.
