DDSY1672 type
Single phase electronic prepaid energy meter (RS485 remote control type)
product overview
The DDSY1672 single-phase electronic prepaid energy meter uses microelectronics technology to measure electrical energy, and the product complies with the standards of GB/T17215. 321-2008 "Level 1 and Level 2 Static AC Active Energy Meters" and GB/T18460.3-2001 "Prepaid Energy Meters". This meter has 485 networking meter reading function and networking control power on/off function, which facilitates the property management department to real-time grasp the user's electricity consumption situation and facilitate monthly electricity consumption statistics. The design of the electricity sales management system is rigorous, easy to use, and can control users' electricity consumption at any time without going to the site, which has won the favor of the electricity management department.
Functional Features
LCD cycle display, clear and intuitive display content.
Using encryption cards and DES dynamic encryption algorithm, the system data is secure and reliable.
◆ Adopting high-power magnetic holding relay, with strong overload capacity and sensitive and reliable action.
The function of writing back the meter parameters after inserting the card is designed rigorously and will not cause any electricity disputes.
High precision, stable performance, low self power consumption, anti-theft, no need for calibration for long-term use.
◆ Network electricity price change function: When the electricity price changes, the new electricity price information can be transmitted to the meter through the 485 network.
Control power on/off function: Through the 485 network, the property management department can control the power on/off of users' electricity meters without leaving their homes.
Power off alarm function: When the remaining power reaches the set alarm value, the electricity meter automatically shuts off to remind users to purchase electricity in a timely manner.
◆ Network meter reading function: With a 485 interface, it can read the electricity consumption of each meter at any time, making it easy for management departments to calculate monthly electricity consumption.
◆ Load control function: When the load exceeds the set value, the electricity meter will automatically cut off power. After the load decreases, the electricity meter will automatically restore power supply in about 5 minutes.
Both networked control and IC card electricity sales can be achieved simultaneously.
