1.General：

The ACR10R opening and closing type transformer guide rail meter integrates measurements of all electrical parameters and comprehensive energy monitoring and examination management. Meanwhile, it also has various peripheral interfaces for user to choose: with RS485 communication interface, Ethernet interface and RJ45 interface, using MODBUS-RTU protocol to meet communication network management needs; Interfaces with switch input and relay output can realize remote signaling and remote control of circuit breaker switch. It is very suitable for real-time energy monitoring system with an LCD screen and panel buttons to realize parameter setting and control.
