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.

Time division multiple rate function

It has the function of dividing peak, off peak, off peak, and off peak periods into multiple rates, and can be set to 6 rates for larger periods; Time division metering for forward and reverse active energy metering, reactive energy metering for any combination of four quadrants and four quadrants, and reactive energy metering for combination 1 and 2.

Communication function

In conjunction with the meter reading system, it can read various electricity data from the meter and support the DL/T645-1997 multifunctional energy meter communication protocol.

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 A, B, and C phases.

Data storage

It can store historical electricity consumption data for the current and previous 12 months, and can store monthly total, peak, peak, average, and valley electricity consumption data.

Storage function

Can store historical electricity data for the past 13 months.

Measurement function

It can measure the large demand and occurrence time of bidirectional active power, bidirectional reactive power, and four quadrant reactive power.
