M9533 is a family of MicroTran System Analyzer devices, a line of power monitors, voltage converters, and sensors used in the electrical distribution and power industries. The M9533 line is designed to detect, analyze, and manage the energy flows of a variety of energy sources, from AC, DC, and solar power. They also offer precision measurements of power, current, frequency, and line voltages, as well as load tracking and harmonic analysis. The M9533 also supports remote control and communication options including Modbus, BACnet, and DNP3. It also provides insights into energy consumption patterns and identifies energy waste in terms of power, voltage, and harmonics.
