The Qingdao Qingbiao three-phase intelligent cost control meter adopts the State Grid protocol, which can realize card insertion for electricity sales (subdivision model DTZY2026-RS485), remote electricity sales through RS485 network wiring (subdivision model DTZY2026-RS485, suitable for centralized installation, requiring wiring), or 4G wireless remote prepaid electricity sales (subdivision model DTZY2026-4G, suitable for decentralized installation, no wiring required). Its main functions are as follows:

1: State Grid standard, IC card local fee control, pay first, then use electricity;

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

(External control switch) Mutual inductance voltage 3 * 100V 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: DTZY2026-RS485: RS485 remote prepaid (low-voltage wiring after centralized installation), IC card used as power transmission management card in emergency situations;

4: DTZY2026-4G: 4G remote prepaid (can be used for communication after installation), IC card can be used as a power transmission management card in emergency situations;

5: Can be charged at 4 or 5 rates (total, peak, flat, valley, deep valley);

6: It is possible to remotely modify electricity prices and time of use settings;

7:haveSuitable for all parts of the countryTime of use billing function;

8:The recharge amount is written into the energy meter and can be exchanged with the backend of the electricity sales system for datacomparison.

9: Superinstruction fetchingThe data block related to prepaid information shall at least include the following contents:Total electricity consumption, peak electricity consumption, off peak electricity consumption, off peak electricity consumption, valley electricity consumption,Deep Valley Electricity,Accumulated purchase amount, current purchase amount, remaining amount, overdraft amount, current electricity price, alarm amount, overdraft threshold amount, hoarding threshold amount, etc.Instantaneous data block: A, B. C phaseVoltage, A, B. C phaseelectric current,Zero line current, A, B,Ceach otherActive power, A, B. C phasePower factor;

10: When recharging remotelyhaveElectricity purchaseRevocation function: By giving instructionsRemote rechargeThe sales amount of electricity and the function of recalling from the meter;

11: Can achieve postpaid remote closing and opening function;

12: 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.

13: It can be equipped with Qingdao Qingbiao Energy Management System software to realize computer card free remote recharging and mobile phone WeChat official account recharging. All software is self-developed, free of third-party control, and can operate without faults for a long time.
