PowerLogic™ EM3500
Description
The EM3500 Series DIN Rail Meter combines exceptional performance and easy
installation to deliver a cost-effective solution for power monitoring applications. The
EM35xx can be installed on standard DIN rail or surface mounted as needed. Pulse
output and phase alarms provide additional versatility. The Modbus and BACnet
output options offer added exibility for system integration. The data logging
capability (EM3555 and EM3560) protects data in the event of a power failure.
Modbus, pulse output, and phase alarms are all provided to suit a wide variety of
applications.
Additional pulse inputs on EM3560 provide an easy way to incorporate simple ow
sensors to track gas, water, steam, or other energy forms using a BACnet system in
addition to full monitoring of electrical energy.
The EM3555 models adds 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 track all energy data, ensuring accuracy
in billing and crediting.
