Four wire smart meter

Product Features

·Measurement and storage:

Measure bidirectional, time-sharing, and phase separated (A, B, C) active and four quadrant reactive energy, and set the combination of active and reactive energy according to different user properties;

It can store the total electricity and electricity data of each rate for 12 settlement days.

·Measurement function:

Phase separated voltage, current, active power, reactive power, apparent power, power factor, frequency, etc.

·Rate Period:

Supports four rates: peak, off peak, flat, and valley; 8 time periods can be set; Support the setting of public holidays.

·Communication display:

Independent infrared and RS485 communication channels;

LCD backlight display, button cycle display, automatic cycle display, power outage wake-up function.

·Event record:

Record the last 10 events such as voltage loss, full voltage loss, current loss, phase failure, data reset, power on/off programming, timing, opening the meter cover, opening the terminal cover, event reset, meter reset, tripping, and closing.

·Load record:

Support 6 types of data curves, each type of curve can be recorded at different time intervals.

·Remote cost control:

It can remotely send tripping and closing commands to control the power on and off of users, and the control switch can be selected as built-in or external.

·Local cost control:

Implement the management function of paying first and then using electricity. When the user owes money, the electricity meter will automatically turn off and cut off the power to the user. When the user purchases electricity and recharges it through the CPU card or RF card, they follow the prompts to complete the specified operation, and the energy meter resumes power supply (remote control priority is higher than local control priority).

·Step by step electricity price:

Support annual step (two sets of step parameters can be set) and monthly step (two sets of step parameters can be set).

·Carrier communication function:

Users can also customize other communication methods, such as wireless, GPRS/CDMA modules, etc.
