•To use high-performance single micro-processor and DSP processing technology, to collect current, voltage, active power, reactive power and power factor from current circuit and distribution equipment, To realize distribution monitoring.

•Real-time data acquisition, historical data storage, harmonic analysis, fault alarm.                                  • Communication function: Communicate with on-site computer or remote network via RS485 or RS232.

•To use regional control principle to realize joint compensation, separate compensation and comprehensive compensation, ensure the optimal compensation method, the effect is the best.
•With perfect limit alarm and overvoltage, under voltage, no phase, load unbalance, harmonic exceed alarm.
•Switch frequency statistics: Display number of switch in every month and total number of switch.
