detailed description:
Qingdao's high-quality multi-user electricity meter adopts a one household one measurement method to ensure accurate measurement. The display adopts a backlit large LCD screen with stable quality, making it an ideal product for high-end power management applications. Multi user prepaid electricity meters can be recharged through the internet. Multi user prepaid electricity meters have RS485 interfaces, which can be used for wired, wireless ZIGBEE, wireless LORA, wireless GPRS and other meter networking. The network is used by servers and clients through TCP.
DDSHY2026 prepaid multi-user energy meter is a high-tech product developed and produced by Qingdao Qingbiao Company. It adopts microelectronics processing technology, SMT surface packaging welding, and online testing technology, which can centrally detect the electricity consumption of up to 36 households and display it in a cyclic manner. The prepaid method is flexible: electricity can be purchased through RF cards; It is also possible to purchase electricity remotely through 485 networking. The sensing element adopts the 1J77A high permeability micro current and voltage transformer developed by the German VAC vacuum melting company. Compared with manganese copper (constantan) shunt elements, it has the characteristics of high accuracy, wide range, low self power consumption, and strong anti-interference ability; The relay adopts high-performance high-power magnetic holding relay, which has the characteristics of high voltage resistance and strong overload capacity.
The DDSHY2026 multi-user combination electric energy meter can be widely used in residential buildings, collective apartments, school apartments and other electric power plants. It has the functions of small size, convenient meter reading, prepayment, and anti-theft, and is an ideal substitute for ordinary electric energy meters.
Main Function Description of Multi User Prepaid Energy Meter
1. Prepaid function (countdown), users purchase electricity first and then use it, swipe their card to buy electricity or recharge online. There are various payment methods for electricity meter arrears and power outages.
2. Overload protection function, when the user's load exceeds the maximum load, the user automatically loses power protection.
3. Power off automatic recovery function, after user power off protection, within the specified number of power outages, the maximum power of the user drops to within the allowable range, and the system automatically restores power supply.
4. Low battery alarm function, which can set the alarm battery level. When the user's electricity consumption is lower than the set value, it can provide a power outage prompt to the user and automatically restore power supply or swipe the user card to restore power supply (the 485 network networking mode can set the automatic power restoration time).
5. Allow overdraft function, different overdraft power levels can be set according to the user's reputation, and the power will automatically shut down after exceeding the set parameters.
6. The remaining amount, cumulative power, current voltage, current, and power display functions are used in the electric meter. The meter adopts LCD display to record and cyclically display the user's remaining amount and cumulative power, and can be queried through the upper computer or LCD query device.
7. The account number setting function can be set through the upper computer, and the account number can be displayed in real-time on the LCD screen.
