Post paid (remote reading and control type) DDSH1521 multi-user centralized post paid electricity meter for 24 households and below

product overview

The DDSH1521 multi-user centralized energy meter is a fully electronic intelligent multi-user energy meter widely used in industrial and mining enterprises, urban and rural residential areas, rural power grids, old building renovation residential buildings, collective apartments, apartments and other electric power plants. It has the characteristics of high precision, wide range, low self power consumption, strong anti-interference ability, small size, convenient meter reading, prepaid, anti-theft and other functions. It is an ideal substitute for ordinary energy meters. This product is a high-tech product produced using microcomputer technology and SMT surface welding process. This series of multi-user energy meters has the advantages of simple structure, low cost, accurate measurement, and easy maintenance. Single phase can reach up to 36 households, and three-phase can reach up to 12 households. It can also mix single and three-phase measurement and cyclically display the electricity consumption and remaining electricity of each user. It can centrally detect and cyclically display the electricity consumption of up to 30 households, and can also purchase electricity remotely through 485 networking. Cooperating with our company's self-developed far-infrared handheld meter reading device or remote network meter reading system, intelligent management can be achieved.

Main performance characteristics

The case is made of cold-rolled steel plate stamping, which has the advantages of good sealing, beautiful appearance, compact structure, etc., and complies with the national standard GB/T17215-2002;

◆ Modular internal structure for easy maintenance;

Capable of measuring electrical energy in both positive and negative directions, and accumulating it in the same direction, effectively preventing theft and leakage;

◆ Easy to install, convenient, and effectively saves labor costs;

Small in size and low in power consumption, its power consumption is only 5% of that of mechanical meters in the same household;

◆ Can achieve far-infrared meter reading and computer networking meter reading;

◆ Using dedicated wiring terminals and double bolt crimping, the connection is convenient and reliable, effectively preventing terminal loosening and sparking;
