1. Overview

DDSY series single-phase electronic prepaymentElectric energy meter,Adopting advanced ultra-low power solid-state integrated circuit technology andSMT advanced technology is used for measuring AC single-phase active energy and is widely used for measuring the electricity consumption of residential buildings, offices, shops, etc. Application of computer power sales softwareManagement, purchase electricity first and then use itOne card, one meter. If the card is lost, it will be replenished without losing power. If the battery is low, the user will be alerted to purchase electricity. If the battery is zero, the power will automatically trip and cut off.

Its performance meets the technical requirements for single-phase electronic energy meters in GB/T 17215.3 21-2008 "Special Requirements for AC Measuring Equipment Part 21: Static Active Energy Meters (Level 1 and Level 2)" and GB/T18460.3-2001 "IC Card Prepaid Electricity Sales System Part 3: Prepaid Energy Meters" standards.

2. Functional Features

2.1 Accurate and stable energy measurement, no need for adjustment after the whole machine leaves the factory, can extend the calibration cycle, greatly reduce the workload of testing and verifying energy meters in the power department, and have significantly improved reliability compared to similar products.

2.2 Bidirectional metering function, accurately measuring forward and reverse electrical energy, accumulating total electrical energy, with anti-theft function.

2.3 Using photoelectric isolation to output electrical pulse signals, error detection can be performed, and the luminous tube indicates the power consumption.

2.4 The instrument has the advantages of wide load, high accuracy, high reliability, high sensitivity, straight error curve, small size, light weight, low power consumption, strong overload capacity, and easy installation.

2.5 The instrument and electricity sales system must be used in conjunction. New meters must first open an IC card account and then plug in the electricity meter for use. When the remaining power is insufficient, electricity can be purchased. For detailed operating instructions, please refer to the help manual of the power sales system.
