1. Product Introduction

The DDSH1703 multi-user electricity meter is mainly used for electricity management in student apartments. The electricity meter adopts a LCD screen display, which can display Chinese characters and has backlight; Display complete content; Users can choose between single circuit control or dual circuit control. The multi-user energy meter with dual circuit control can control lighting and sockets in one circuit. Each circuit can be set with a separate load power, and if the power exceeds the set power, the meter will cut off power without affecting the power consumption of the other circuit, making it convenient for the school to manage the apartment and ensuring the safety of students' electricity use.

2. Product functional features

● Encryption

A dedicated anti stealth watchdog circuit ensures more reliable operation.

● Display information

※ It adopts a large LCD screen display, which can display Chinese characters and has backlight.

When the electric energy meter is turned on, it first displays: student apartment, meter number, unit number, three-phase voltage of phase A, phase B, and phase C, current date, and current time.

A single circuit energy meter can cyclically display the current voltage and power consumption of each user.

※ The energy meter displays in a cyclic manner: household number, house number (if set), remaining power, electricity consumption, gifted power (if set), number of power purchases, first circuit limited power, second circuit limited power, disconnected 1 (forced power-off of circuit 1), disconnected 2 (forced power-off of circuit 2), disconnected 3 (zero power-off), disconnected 4 (power-off alarm power-off), disconnected 5 (high-power power-off).

The energy meter can be equipped with a query button. Long press the query button, and the energy meter can display the on/off status of circuit 1 and circuit 2 during various time periods from Monday to Sunday.

● Measuring users

Single circuit can measure the usage of 39 users, dual circuit can measure the usage of 18 users, centralized control, and household metering.

● Room number display

When opening an account, the user's room number information can be set, so that the electricity meter can directly display the room number, making it convenient for users to view.

● Electricity load control

A single circuit can set power restrictions for each household (through software settings), while a dual circuit can set two different power restrictions for each household's two circuits (through software settings). When the user exceeds this set power, the electricity meter will automatically shut down, and the household's electricity load will decrease. After 5 minutes, the electricity meter will automatically resume power supply.

● Online remote electricity sales

Through the 485 networking method, the management department can directly sell electricity to meter users within the system through the management system.

● Remote control of power on and off through networking

Through management software, the management department can force power on and off of users within the remote control system without losing their data.

● Networked remote meter reading

The management department can retrieve users' electricity consumption information at any time through this system. During meter reading, the management department can retrieve the remaining electricity of a certain household or all users of a certain meter.
