Functional classification

Measurement parameter function: It can measure active power, reactive power, forward active power, reverse active power, forward reactive power, reverse reactive power, four quadrant reactive power, and other electrical quantities.

• Parameter monitoring function: 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.

• Time sharing metering function: Time sharing metering of forward and reverse active power, four quadrant reactive power, and maximum demand.

Data storage function: It can store 12 months of historical electricity data.

• Load curve: with 6 types of data recording load curve functions; You can freely choose to draw a curve graph from data such as voltage, current, frequency, power and power direction, power factor, total reactive power, four quadrant reactive power, current demand, etc.

• Display function: wide viewing angle, large screen LCD display, with rich status indication and Chinese character auxiliary prompt information; It can display the monthly electricity consumption data for the past three months.

Anti electricity theft function: It has event recording functions such as lid opening, voltage loss, current loss, phase failure, current imbalance, power failure, reset, reverse phase sequence, and reverse electricity being included in forward electricity, to prevent users from illegally removing or cutting off voltage and current wiring.

• Data output and communication functions: It can be displayed through buttons, read through infrared handheld devices and RS485 communication ports, and with the meter reading system, can read various electricity data of the meter. It supports DL/T645-2007 multifunctional energy meter communication protocol.

• Cost control (carrier) function: using RS-485 and carrier power line for data communication; Without IC card mount, supports remote communication for opening and closing. I can remotely control the opening and closing of the electric energy meter and set parameters such as time periods, thereby implementing remote management of users' electricity consumption. II can achieve automatic deduction and payment functions, as well as functions such as overdue tripping. When the electricity bill of the meter is insufficient, it can be remotely alarmed. When there is no electricity bill, it can be remotely tripped and powered off, making operation and management very convenient.
