Din Rail Single Phase Electricity Meter

Introduction

DDZ1737 din rail single phase energy meter is mainly used for electric power system, communication industry, construction industry and other electricity metering needs. It is a good choice for real-time measurement of voltage, current, active power, reactive power,frequency, positive and negative energy and other parameters. Adopting the standard DIN35mm din rail mounting and modular design, it is characterized with small volume, easy installation and easy networking, widely applied into the internal energy monitoring and assessment for industrial and mining enterprises, hotels,schools, large public buildings, etc.

Main Functions

1. Supporting 1~4 loop metering function

2. Each loop meter has import/export active and combined active data

3. Each channel meter can measure the current, voltage, frequency, power factor, active power, reactive power, apparent power

4. Can record and alarm of undervoltage, overvoltage, supervoltage and phase loss events;

5. On the meter reading day of every month, the electric quantity will be settled automatically
