Veris Industries E51H2 Power & Energy Meter w/RS485 2-Wire BACnet MS/TP


The Veris Industries E51 series is an enhanced power & energy meter which combines exceptional performance and easy installation to deliver a cost-effective solution for power monitoring applications. The E51 can be installed on standard DIN rails and can be surface mounted as needed. The Modbus and BACnet output models offer added flexibility for system integration. The data logging capability (E51C3 & E51H5) protects data in the event of a power failure. Combinations of serial communication, pulse output and phase alarms are provided to suit a wide variety of applications. Additional pulse inputs on models E51H2 & E51H5 provide an easy way to incorporate simple flow sensors to track gas, water, steam or other energy forms using a BACnet system.

The E51 also features bi-directional monitoring which is designed expressly for renewable energy applications, allowing measurement of power imported from the utility grid as well as power exported from the renewable energy source (for example: solar panels). 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.
