220V RS485 Two Phase Three Wires Anti-Tamper Watt Hour Meter With Waterproof Design
Two Phase Three Wires Anti-Tamper Watt Hour Meter is a smart metering device with special design for nation smart grid. It can measures the positive active power, reverse active power and power in A, B, C phase which can be measured.
1. Intelligent Design: Imported single-chip which controlled by microcomputer, full digital metering, with advantages of high accuracy, good linearity, wide range, low consumption and prevent from electricity stolen.
2. Reliable Design: Perfect power source and electromagnetism compatible design, which are suitable to the strong electromagnetism disturbance and big occasion of power source fluctuation.
3. Cover to Meter: Fully sealed dustproof and waterproof design, material of cover has excellent flame retardant and anti-corrosion, anti-aging properties.
4. On-Off Manner: Build in or external switch can be optional.
5. Communication Mode: Infrared, RS485 interface or carrier communication module(Optional).

A. Measure total amount of forward active, reverse active energy and restore the data, which are indicated by LED
B. The screen of LCD will display 'reverse' when power reverse.
C. Measure reverse active energy separately
Measuring multi-tariff in different time internals:
The meter has 4 kinds of tariff defined as sharp, peak, shoulder and off-peak. The meter can be programmed as single tariff, double tariff and three-tariff or four-tariff. During each tariff interval, the meter can measure forward/reverse active energy.
Tariff and Time Intervals:
The meter has 12 programmable interval tables, of which each can set up to 12 intervals ass harp, peak, shoulder and off-peak during 24 hours.
The minimum unit of each tariff interval can be set up as 1 minute.
The meter can automatically switch calendar, time and leap year.
Measuring real- time power, Measure real-time power through pulse constant and pulse interval.
The function of data-transfer:
The meter can transfer data automatically on the reading date( 1st to 27th are programmable ).That is the transfer of total forward/ reverse active energy.The meter can store the data in the previous 12 months and store the data for 10 years at power failing.
