Overview
AMB intelligent bus AC monitoring device is a new development to cater for smart power bus bar. It consists of a feeding detection module and a tapping detection module and integrates functions of conventional power measurements, electricity monitoring, consumption assessment and control. It also boasts the online alarm function and enables the independent off-line operation. It monitors the bus bar interface temperature in real time.By virtue of 2 RJ45 communication ports (1 in and 1 out) and MODBUS-RTU protocol, it is easy and reliable to upload the monitoring data to the touch screen of the main controller for centralized monitoring, ensuring safe and reliable operation of the system. The smart bus bar monitor has several benefits such as flexible and convenient wiring so that it is a good substitution of the traditional centralized array cabinet.
