IC card insertion type single-phase energy meter

IC card insertion type single-phase energy meter

1. Product Introduction

The DDSY1703 single-phase electronic prepaid energy meter is an advanced domestic product manufactured using advanced solid-state, integrated technology, and SMT process. It has the characteristics of anti-theft, high precision, high reliability, high overload, and low self power consumption. It is an ideal product for the current reform of the electricity system, realizing the commercialization of electricity, solving the difficulty of electricity billing, and facilitating unified management of electricity consumption.

2. Product Function Introduction

● It has a prepaid function, where users pay first and then use electricity. When the remaining power in the meter reaches zero, the meter will automatically cut off power.

One household, one card, using DES dynamic encryption algorithm, strong encryption, the entire system will not be cracked.

Active energy measurement, long-term operation does not require calibration, measures electricity consumption in both positive and negative directions, and accumulates energy in the same direction, with anti-theft function.

The display mode of the electric energy meter includes five digit digital tube display and LCD screen display. When the five digit digital tube is working normally, it will cycle and display the remaining power, total power consumption, and number of power purchases in sequence; The LCD screen displays information such as remaining power, meter number, and cumulative electricity consumption.

Power outage alarm function: When the remaining power in the meter reaches the power outage alarm value (which can be set through software), the meter will automatically power off. After the user inserts the card, the meter will automatically resume power supply until the remaining power in the meter reaches zero. At this time, the meter will power off again. The user needs to purchase a brush card before continuing to use electricity to remind the user to purchase electricity in a timely manner.

● Load control function: Within 5 minutes, if the average power consumption of the user exceeds the specified value (which can be set through software), the meter will automatically cut off power. After 5 minutes of the user's power consumption, the meter will automatically restore power supply.

● One card meter reading function: The management department can use the meter reading card to read the information inside the electricity meter and transmit it to the computer through the card reader. One meter reading card can continuously read 200 electricity meters.

Product execution standard: GB/T17215.321-2008 "Special Requirements for AC Measuring Equipment Part 21: Static Active Energy Meters (Level 1 and Level 2)"; All technical requirements of GB/T18460.3-2001 "IC Card Prepaid Electricity Sales System Part 3: Prepaid Electricity Meter".

● Verification regulations for product execution: JJG1099-2014 "Prepaid AC Energy Meter".
