Senva EM-RS485 : Compact BACnet & Modbus Energy Meters, 2-wire, BACnet MS/TP, Modbus RTU Outputs, Buy American Act Compliant, 7 Year Limited Warranty

The EM Series is the safest and fastest meter to install on the market. The unique design makes the meter entirely low-voltage. Ideal for retrofits as the high- voltage components are embedded in the Current/Voltage Transducer (CVT). Experience high-accuracy data-rich power metering in a compact, easy-to-use package. Meter recognizes CVTs automatically, eliminating time-consuming scaling. Each CVT uses digital communication with the meter for superior noise immunity The CVT are individually calibrated and can be mixed or matched as independent meter channels--1% total accuracy! Features both Modbus and self-configuring plug-and-play BACnet MS/TP for seamless integration.

Applications

  • Energy Management & performance contracting
  • Monitoring for commercial tenants
  • Activity-based costing in commercial & industrial facilities
  • Real-time power monitoring & load shedding
  • Audits/temporary monitoring
  • Distributed generation

Features

  • Split-core Rogowski CVTTM senses both voltage and current, communicating with the meter through a low voltage data cable
  • Easy to install Rogowski CVTTM is lightweight and compact
  • True 3 channel meter--mix and match different voltages and currents per phase on HVAC equipment
  • EM-RS485 self-configures baud rate, serial formal, protocol type and address - eliminating additional configuration steps
  • No scaling required--easy set up
  • Meter base is entirely low voltage--locate external to panel if desired
  • 2 pulse inputs can connect to a variety of pulse output meters (water, gas, steam, etc.)
  • Versatile DIN, screw, and magnetic mount
