major function
Measurement function
Measurable active, reactive, forward active, reverse active, forward reactive, reverse reactive, four quadrant reactive and other electrical quantities.
Display function
Dot matrix LCD display, capable of displaying electricity consumption data for the past three months.
Anti electricity theft function
It has the function of recording events such as lid opening, voltage loss, current loss, phase failure, current imbalance, power failure, reset, reverse phase sequence, and reverse power being included in forward power, to prevent users from illegally removing or cutting off voltage and current connections.
Load curve function
It has the function of recording 6 types of load curve data, and can freely select and draw curve graphs in voltage, current, frequency, power and power direction, power factor, total reactive power, four quadrant reactive power, and current star demand data.
Time division multiple rate function
It has the function of dividing peak, off peak, off peak, and off peak time periods into multiple rates, and can also choose to divide peak, off peak, and off peak time periods to set 6 rates.
Parameter monitoring
It can monitor real-time values of voltage and current in each phase, as well as real-time parameters such as active power, reactive power, power factor, phase angle, and phase of the three-phase total and phases A and C.
Data storage
Can store historical electricity data for the past 13 months.
Communication function
It can be read through button display, infrared handheld device, and 2RS485 communication port. With the meter reading system, it can read various electricity data of the meter and support DL/T645-1997 and DL/T645-2007 multifunctional energy meter communication protocols.
Measurement function
It can measure the large demand and occurrence time of bidirectional active power, bidirectional reactive power, and four quadrant reactive power.
