The E5x series DIN rail meter combines exceptional performance and easy installation to deliver a cost-effective solution for power monitoring applications. The E5x can be installed on standard DIN rail or surface mounted as needed. The BACnet output model offer added flexibility for system integration. Combinations of serial communication, pulse output and phase alarms are provided to suit a wide variety of applications. Additional pulse inputs on E5xHx provide an easy way to incorporate simple flow sensors to track gas, water, steam, or other energy forms using a BACnet or LON system. In this way, a facility administrator can track all energy data, ensuring accuracy in billing and crediting. They are also useful for monitoring loads that use regenerative braking.
