major function

Measurement function

Measurable active, reactive, forward active, reverse active, forward reactive, reverse reactive, four quadrant reactive and other electrical quantities.

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 also choose to divide peak, off peak, and off peak periods, with a maximum of 4 rates set.

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.

Prepaid function

① Alarm for power outages, insufficient remaining electricity bills, and excessive power Configure the electricity credit function to ensure uninterrupted electricity usage in emergency situations Rich functional cards to complete functions such as electricity purchase, parameter setting, meter reading, relay detection, etc.

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.

Display function

Wide viewing angle, large screen LCD display, capable of displaying electricity consumption data for the past three months; Can store historical electricity data for the past 13 months.

Communication function

Meter reading can be done through button display, infrared handheld device, and RS485 communication interface. With the meter reading system, various electricity data of the meter can be read, supporting DL/T645-1997 communication protocol.
