How to choose a multi-user electricity meter in Beijing? What are the specifications of prepaid multi-user electricity meters in Beijing? How much is the prepaid electricity meter for Beijing card swiping? Which is the best quality multi-user electricity meter in Beijing?
DDSHY2026 remote control prepaid/card swiping prepaid multi-user energy meter measures each channel separately, with a modular structure and higher security and reliability. Specially designed for high-end users and usage locations with requirements for quality, performance, and reliability.
Main technical features:
1. The electricity meter adopts the State Grid meter processor, which has low power consumption, high integration, fast operation speed, stability, and reliability.
2. Modular protective structure, smaller meter box volume, and orderly internal wiring.
3. The power supply adopts a sealed transformer, which reduces the electromagnetic interference of the power supply on weak current circuits.
4. An internal relay detection function has been added to the electricity meter, which can detect the status of the relay online through software. The software can judge the quality of the relay by itself.
5. The electric meter has a phase loss protection function. For three-phase users, if there is a phase loss caused by power supply phase loss or relay failure, it can automatically perform phase loss protection to ensure the safe operation of the user's three-phase equipment.
6. The incoming and outgoing lines of the electric meter use dedicated wiring terminals, which have stronger current carrying capacity and are more convenient for on-site construction;
7. Multiple billing methods are adopted: RF card swipe prepayment, network remote recharge prepayment, and network remote postpaid.
8. Using State Grid high-precision measurement chips, each channel is measured separately, and the measurement accuracy can reach 0.5S level.
9. Remote recharge adopts State Grid DES encryption technology. For end users, provide application software in wired 485 connection, wireless ZIGBEE transmission, GPRS remote transmission, and LAN transmission environment. Provide comprehensive communication protocols for secondary development users.
