Prepaid (induction terminal type) for 24 households and below

DDSH1521 multi-user centralized prepaid electricity meter

major function

Prepaid, remote meter reading, remote control, overload protection, timed power outage function, malignant load identification.

main features

◆ Prepaid: It can realize prepaid function and manage electricity sales records.

◆ Arrears shutdown: When the prepaid electricity is less than the set value, an automatic alarm will be triggered. Automatically cut off the user's power supply when overdue.

◆ Overload protection: When the user exceeds the set load, the user automatically loses power protection.

Remote control of power outage: The system automatically controls the power supply of users who owe bills, improving the rate of electricity bill recovery.

Power off automatic recovery: Due to overload protection, after a power outage, within the specified number of power outages (0-6 times), if the user's power usage is restored to the allowable range, the system can automatically restore power supply.

◆ Scheduled power outage: 12 scheduled time periods can be set for convenient management of electricity usage in apartments and dormitories.

◆ Support dual circuit control: using dual circuit power supply. One route is used for lighting, while the other route supplies high-power electrical equipment such as air conditioning and water dispensers. One of the paths for lighting can be limited in current and identify malignant loads. (Same for single household three circuit control)

◆ Safe electricity management: equipped with load recognition function. By monitoring the comprehensive parameters of users' instant access devices, the access of malicious load devices can be restricted, effectively achieving safe electricity management.
