1. Core Functions and Application Scenarios
2. 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.

1. International Applicability and Certifications
2. 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.

1. Purchase and Support
2. 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.
