Product  Detail

1. Product Brief Introduction

DDS722 Single-Phase Electronic Watt-Hour Meter adopts advanced solid integrated circuit technology that can realize ultra-low power dissipation and advanced SMT technique to meter single-phase AC(alternating current) active energy with the frequency of 50HZ or60 Hz. Its various performance indexes conform to the technical indexes that GB/T17215.32-2008 'Static AC Active Watt-Hour Meters Of Class 1 Or Class 2' and IEC62053-21-2003 'Class 1 And Class 2 Static AC Active Watt-Hour Meter for the single-phase static watt-hour meter ' requires from the single-phase static watt-hour meter.

The meter has the features of accurate, stable and reliable metering, good anti-electromagnetic interference, low power consumption, high accuracy, anti-electricity-theft, wide range, long life and so on.

2. Function and features

-  Electric energy metering function: the metering of the total active electric energy, the quantity of electricity in reverse way can be accumulated in normal way.

- The interface has optical coupling isolator and the active and passive pulse.

- When the electric energy is in reverse way, the light will be on to get attention.

- The meter has the power failure display function. When the external power source has no electricity, the meter will show the last electric energy data. 

3. Main Technical Data

The meter is highly precise, highly sensitive. Highly reliable wide load rang, low power loss, the power in double directions. Both positive and negative work can be measured in accumulated same direction. So it can prevent any power steeling, such as reverse steeling. live-earth wire steeling, short circuit and so on.
