Advanced 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.
