485 networked remote control single-phase energy meter

485 networked remote control single-phase energy meter

1. Product Introduction

The DDSY1703 single-phase electronic networked prepaid energy meter adopts microelectronics technology to measure electricity. The meter has 485 networked meter reading function and networked control of power on and off function, which facilitates the property management department to timely grasp the user's electricity consumption situation and conduct monthly electricity consumption statistics. The design of the electricity meter sales management system is rigorous, easy to use, and can control the power on and off of the user's electricity meter at any time without going to the site, which has won the favor of the electricity management department.

2. Product functional features

● LCD display, during normal operation, the LCD screen cyclically displays F1: remaining power, F3: meter number, F6: cumulative power consumption and other information.

● It has load control function. If the electricity load exceeds the set value (which can be set through software), the meter will automatically cut off power. When the load drops to the allowable range, the power supply will automatically resume.

● Internet connected electricity sales function: When users need to buy electricity, the property management department only needs to input the purchase amount through the electricity sales software and transmit the amount of electricity to the meter through the 485 line, without the need for users to swipe their cards on the meter.

● 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.

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, and the data inside the meters will not be lost.

● SMS power purchase reminder function: When the remaining power in the user's meter does not reach a certain value (which can be set through software), the power sales system can send a text message to the user through SMS to remind them that the remaining power in the meter is low and to purchase electricity in a timely manner.

Both networked control and IC card electricity sales can be achieved simultaneously. Users can choose to use networked electricity sales or use cards for electricity sales.
