DDS 155 single phase electronic watt-hour meter uses imported specific large-scale integrated circuits and other advanced technology.It can measure AC single phase active electric power which the rated voltage is 220V and frequency is 50Hz.
It can measure forward and reverse active power accurately and it calculates accumulatively in the same direction.
It can prevent electric larceny at the same time.
It outputs heartbeat through optical couple. LED displays electricity consumption,so that it si easy to control.Technical Parameter
1. Product's Type—Register (5+1), LCD (5+1 or 6+2), LED (5+1).
2. Electric Power Measurement- Positive active power, reverse active power and power in A, B, C phase which can be measured.
3. Intelligent Design—Imported singlechip which controlled by microcomputer, full digital metering, with advantages of high accuracy, good linearity, wide range, low consumption and prevent from electricity stolen.
4. Reliable Design-Perfect power source and electromagnetism compatible design, which are suitable to the strong electromagnetism disturbance and big occasion of power source fluctuation.
5. Cover for Meter-- Fully sealed dustproof and waterproof design, material of cover has excellent flame retardant and anti-corrosion, anti-aging properties.
6. On-Off Manner—Build in or external switch can be optional.
7. Communication Mode-- Infrared, RS485 interface or carrier communication module (Optional).
