We set out to make the easiest to install, revenue grade meter. We started with flexible Rogowski CTs because they’re compact, lightweight, and split-core for easy installation. But we didn’t like their accuracy. So we gave them a brain so they can digitally communicate with our meter. And then it dawned on us you’d appreciate not having high voltage at the meter where you make your digital connections. So we made the voltage connection at the CT itself. Suddenly, we were measuring current and voltage in a current transducer. We christened it the CVTTM (Current/Voltage Transducer) and designed it to measure both voltage and current, communicating the data digitally to the meter via plug-in low voltage connections.
The meter recognizes the CVTTM sensors and then scales itself accordingly. If you’re using BACnet or Modbus versions (EM-RS485), it even self-configures its baud rate, eliminating additional configuration steps to provide a full data stream of power variables. Two pulse inputs allows aggregation of additional EM-PULSE meters. With the EM-RS485, the on-board inputs can connect to a variety of pulse output meters (water, gas, steam, etc.) for increased flexibility..
The entire assembly is easily mounted inside the electrical panel. Multiple mounting options including DIN rail adapter, snap-in mounting ears and integrated rare earth magnets to secure on any ferrous enclosure or surface. Additional features include diagnostics for assistance during installation. User programmable pulse scales, pulse width/alarm options, energy type, balanced load multipliers and PowerPrint power quality alarm.
