DESCRIPTION
The E5x Series DIN Rail Meter combines exceptional performance and easy
installation to deliver a cost-eective solution for power monitoring applications.
The E5x can be installed on standard DIN rail or surface mounted as needed. The
Modbus, LON, and BACnet output models oer added exibility for system
integration. The data logging capability (E5xC3 and E5xx5) 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 E5xHx and E50Fx provide an easy way to incorporate
simple ow sensors to track gas, water, steam, or other energy forms using a
BACnet or LON system.
The E51 models add a bi-directional monitoring feature 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 (e.g.
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.
