Qingdao Qingbiao three-phase remote prepaid electricity meter adopts the State Grid protocol, which can realize card insertion for electricity sales (subdivision model DTSY2026-RS485), RS485 network wiring for remote electricity sales (subdivision model DTSY2026-RS485, suitable for centralized installation, requiring wiring), or 4G wireless remote prepaid electricity sales (subdivision model DTSY2026-4G, suitable for decentralized installation, no wiring required). Its main functions are as follows:

1: According to the State Grid standard, IC card sales of electricity require payment before use;

2: (External control switch) Mutual inductance voltage 3 * 220/380V current 3 * 1.5 (6) A;

(Internal load cut-off) Straight through voltage 3 * 220/380V current 3 * 10 (40) A;

Direct voltage 3 * 220/380V current 3 * 15 (60) A;

Direct voltage 3 * 220/380V current 3 * 20 (80) A;

Direct voltage 3 * 220/380V current 3 * 30 (100) A;

Equipped with phase loss tripping protection function.

3: DTSY2026-RS485: RS485 remote prepaid (low-voltage wiring after centralized installation), IC card used as power transmission management card to overdraw power in emergency situations;

4: DTSY2026-4G: 4G remote prepaid (can be used for communication after installation), IC card can be used as a power transmission management card to overdraw power in emergency situations;

5:Recharge amountConvert to electricityWrite into the energy meter and enable data exchange with the backend of the electricity sales systemcomparison.

6: Data blockreadPrepaid information, including the following:Total electricity consumption, cumulative purchased electricityquantity of electricityThis purchase of electricityquantity of electricity, remainingElectricity level.Instantaneous data: A, B. C phaseVoltage, A, B. C phaseelectric current,A, B,Ceach otherActive power, A, B. C phasePower factor,Total active power, etc;

7: When recharging remotely via RS485 or 4GhaveElectricity purchaseRevocation function: By giving instructionsRemote rechargeThe sale of electricityquantity of electricityThe function of recalling from the electricity meter;

8: Can achieve postpaid remote closing and opening function;

9: The communication protocol adopts DLT645-2007, remoteDuring the electricity sales process, State Grid DES encryption technology is used,Accepting third-party programming applications, the manufacturer provides open-source communication protocols.

10: Can be matched with Qingdao Qingbiao Energy Management System software to achieve:

10.1 Computer card free remote recharge (the computer does not require internet access and is equipped with 4G devices to connect to the computer), without the need for a fixed IP or cloud server;

10.2 For remote recharging of computers without cards and mobile phone WeChat official account, ECS needs to be configured.

All software is independently developed, without third-party control, and can run for a long time without any malfunctions.
