Single-phase Local Payment-controlled Smart Electricity Meter

Introduction of product

Single-phase local payment-controlled smart electricity meter has a variety of types and configurations, such as carrier or non-carrier; CPU card, RF card or remote; external switch or internal switch, etc. All products have adopted large scale integrated circuit, digital sampling technology and SMT technology. They have embedded AC voltage and current acquisition module with high speed and precision, which can accomplish high- precision sampling, as well as real-time accurate energy measurement; meanwhile they encompass such functions as pre-payment, real-time power billing and real-time monitoring.

Functions

Power Measurement function

The total (positive and negative) active power can be measured, and the reverse power is accumulated by positive power.

Freeze function

Freeze and store automatically the power consumption in each hour, at zero o’ clock, custom time, abnormal conditions and the time of rate conversion.

Time-sharing measurement function

Active energy is accumulated and stored respectively by the corresponding time.

Payment control function

Use local (CPU card / RF card) or remote (carrier / RS485) payment control method.

Step tariff function

Two sets of tariff schemes will be conversed automatically when it comes to the appointed time or when power consumption reaches the agreed amount.

Measuring and monitoring functions

Measure, record, and display the current operating parameters of meter, such as voltage, current (including the zero line current), power, power factor, etc.

Power-on and power-off control

It can accept the command and execute its power-on or power-off control.

Alarm function

When the charge balance is less than the limiting charge, or the meter occurs to malfunction, LCD will display alarming indication and the backlight will be continuously on.

Events recording function

It can record such events as clearing power consumption, programming, timing, power failing, disconnecting and reconnecting power, opening meter cover, etc.
