DTZ1506 Class 1 Three-phase Smart Electricity Meters ( Three- phase Four-wire)
Brief Introduction
DSZ1506 Class 1 three-phase smart Electricity Meters (three-phase four-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 optical and electrical isolation pulse output, RS485 communication interface, and easy to extend functionality, meeting the automatic management requirements of power management department;
l Small size, light weight, and easy to install;
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;
