EnergyMAX

EnergyMAXAdvanced power monitoring and control

EnergyMAX is a real-time power-monitoring system ideally suited for AC and DC subsystem applications. The EnergyMAX power-monitoring system applies IEC 61000-4-30 standards for power quality measurements, and offers advanced analytic capabilities including voltage harmonics, dips, swells, and unbalanced phases. EnergyMAX provides easy integration of additional I/O such as DNP3 and Modbus communications, digital I/O, or temperature and vibration sensors to complete a full monitoring system. Features include:

  • Portable and permanent installations
  • Single- and three-phase AC power monitoring
  • High voltage DC circuit monitoring
  • Custom voltage and current measurement ranges
  • 20kS/s/ch simultaneous waveform acquisition
  • Options for control I/O, communications, and memory

Utilities and energy companies around the world are working towards improving power efficiencies, but first they need to understand and monitor the power with more sophistication.  General power quality meters are too slow to capture transients or synchronize data to understand a complete system. EnergyMAX is a distributed real-time power-monitoring system designed to easily integrate into common AC and DC systems. Some common applications include:

  • On board control and monitoring for energy storage systems
  • Energy storage system installation verification
  • Asset and machine monitoring
  • Smart grid component control and monitoring

 

The wide range of configurable measurement capabilities makes EnergyMAX a standard system for smart grid and energy storage monitoring. The following example shows EnergyMAX connected to a solar panel energy storage application.

The following is a typical configuration for a single EnergyMAX distribution location; multiple measurement locations can be synchronized. Higher voltage and current ranges, or customized channels are available.
