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

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.
