DSZ1506 Class 1 Three-phase Smart Electricity Meters ( Three-phase Three-wire)

                                                         

DSZ1506 Class 1 Three-phase Smart Electricity Meters ( Three-phase Three-wire)


Brief Introduction

DSZ1506 class 1 three-phase smart Electricity Meters (three-phase three-wire), applied to  measurement and metering of the various power data from plants,  substations and a variety of enterprises which demand high reliability  and high stability in power, supporting communication by dual RS485.

 

Main Features

l  High accuracy, high sensitivity, anti-submarine logic, high reliability, wide load;

l  With  abundant status indication and auxiliary character message, displaying  comprehensive and clear data, and data logging is accurate, reliable,  and not lost;

l  With  the most optimized design, low power-consumption, can reduce line loss  and improving power supply efficiency when used on a large scale;

l  With a long life and extending test cycle, greatly reducing the tests and calibration workload for power management department;

l  With features of stable performance, feature-rich, anti-jamming;

l  Fully sealed structure and housing to meet the harsh environment of high and low temperature heat applications;

l  The battery box and buttons can be separately sealed by lead, and easily managed by the electricity sector;

 

Main Functions

l  Energy Measurement

Time-measuring of forward active power , reverse active power, four quadrant wattless power, supporting combination of active power and any combination of four quadrants wattless power, metering sub-phase’s forward active, reverse active and four quadrants wattless energy;

l  Demand Measurement

Measuring  the maximum demand and occurring time of forward active power, reverse  active power and four quadrant wattless power by time consumption;

l  Measuring and monitoring

Capable  of measuring, recording, displaying every voltage, current, power,  power factor of total and sub-phase and other operating parameters;

l  Clock, time and rate function

With  calendar, time and leap year automatic switch function. It can switch  automatically between two sets of rates by pre-setting switch time;

l  Data logging

The meter can record and store voltage data for 13 months, and can set and record 6 class load data, store forward active power , reverse active power and four quadrant wattless power for at least 40 days at 1-minute interval, support load curve reading protocol.

l  Event logging

Comprehensive types of event logging, with the function of anti-theft open detection;

l  Freeze

With functions of timing freezing, instantaneous freezing, agreed freezing and daily freezing;

l  Power off meter reading

The meter can be woke up display by button or handwritten when power off, and support reading electric energy data by infrared;

l  Communication interface

With  dual RS-485 communication interface and an infrared communication  interface, communication interface independent of each other;

l  Extended function

l Adaptive AC/ DC can provide auxiliary power supply, after power on, the auxiliary power supply is priority;

l Measurement of apparent power, harmonic voltage, current, power monitoring, power quality monitoring and other functions;
