Chint DTS634 electricity meter

The Chint DTS634 electricity meter is an electronic active energy meter suitable for three-phase power grids, featuring high-precision measurement, intelligent management, and flexible configuration.

I. Technical Specifications and Model Classification

1. **Voltage and Current Ranges*Chint Digital Display Multifunctional Meter PD666-3S3*  

   - Supports multiple voltage specifications: 220/380V (three-phase four-wire), 57.7/100V (three-phase three-wire).  

   - Covers a wide range of current specifications, such as 0.2-0.5(60)A, 10(40)A, 20(80)A, etc., adapting to different load scenarios.  

   - Accuracy classes are divided into Class 1 and Class 2, complying with national standards such as GB/T17215.321-2008.

2. **Operating Environment**  

   - Specified operating temperature range: -25℃ to +55℃; extreme range: -40℃ to +70℃, suitable for harsh environments.  

   - The protection level is usually IP65, with dustproof and waterproof capabilities.

3. **Display and Interfaces**  

   - Display methods include a meter counter, LED, or LCD screen, which can display parameters such as voltage, current, and power in real-time.  

   - Supports RS-485 communication interface and infrared communication, compatible with protocols such as DL/T645, facilitating remote meter reading and data management.

 II. Core Functions and Application Scenarios

1. **Intelligent Measurement and Management**  

   - Supports forward and reverse active energy measurement, with reverse energy accumulated as forward, suitable for scenarios with bidirectional power flow (such as distributed energy access).  

   - Equipped with functions such as prepaid control, step electricity price calculation, and load curve analysis, meeting the refined electricity management needs of commercial and industrial users.  

   - Can store historical data and generate reports, supporting USB export or remote query, facilitating energy consumption analysis and energy-saving optimization.

2. *Reliability Design**  

   - Adopts industrial-grade components and SMT technology, with strong anti-electromagnetic interference capability and stable long-term operation.  

   - Built-in fault detection mechanism, which can automatically identify problems such as wiring errors and voltage abnormalities, and prompt through LED indicators or remote alarms.

3. **Application Fields**  

   - Widely applicable to three-phase four-wire or three-wire power grids, covering industrial, commercial, and residential users, especially suitable for scenarios requiring remote monitoring and prepaid management.

 III. Installation and Usage Notes

1. **Installation Requirements**  

   - Must be operated by professional electricians; the recommended installation height is about 1.8 meters, ensuring firm wiring and compliance with terminal box markings.  

   - The ambient temperature should be between -25℃ and +55℃, avoiding humid, high-temperature, or strong electromagnetic interference environments.

2. **Wiring and Debugging**  

   - Strictly connect the three-phase voltage and current circuits according to the wiring diagram, paying attention to the phase sequence and neutral line access (for three-phase four-wire systems).  

   - Before first use, check the integrity of the lead seal; if damaged, contact the supplier for re-verification.

3. **Data Reading and Maintenance**  

   - Real-time data can be read through the local display screen or communication interface; the blinking frequency of the pulse indicator is proportional to the electrical load.  

   - Clean the shell regularly to avoid dust accumulation affecting heat dissipation; it is recommended to conduct a comprehensive verification by the manufacturer every 18 months.

 IV. International Applicability and Certifications

1. **Adaptability to the North American Market**  

   - **Voltage and Frequency**: The standard model is 50Hz and 220/380V, which needs to be adapted to the US 120/240V, 60Hz power grid through a transformer, which may affect measurement accuracy.  

   - **Certification Status**: Currently, public information does not explicitly mention UL certification or special models for the North American market; users need to bear compliance risks on their own.

2. **Compatibility with International Standards**  

   - Complies with international standards such as IEC 62053-21, supports general protocols such as MODBUS and DL/T645, facilitating access to global energy management systems.

V. Purchase and Support

1. **Channels and Prices**    

   - Users in the United States can consult the import process via Whatsapp: 0086-13811255435, but attention should be paid to voltage adaptation and certification issues.

2. **Technical Support**  

   - The Chinese installation manual can be downloaded from the Chint official website; English materials need to be applied for through international customer service.  

   - The product warranty period is 18 months; purchase vouchers and intact lead seals must be retained to enjoy after-sales service.
