| Product Uses |
◉ Residential & Apartment Building Management: 4G remote prepaid smart energy meters are perfect for rental apartments, dormitories and residential compounds. Tenants can top up electricity online anytime, property managers remotely check power data and cut power for arrears, realizing unattended automatic charging management to reduce manual work.
◉ Factory & Industrial Workshop Energy Monitoring: DIN rail multi-function power meters and three-phase watt-hour meters are installed in industrial control cabinets to monitor real-time power consumption of production lines, record peak & valley power usage data, helping factories optimize power utilization and cut electricity operating cost.
◉ Commercial Malls, Office & Retail Stores: Multi-user centralized energy meters are adopted in shopping malls, office buildings and catering shops for separate sub-metering of each store/office. Remote meter reading avoids frequent on-site inspection, automatic power statistics simplifies monthly electricity bill settlement.
◉ Public Infrastructure & Engineering Projects: Wall-mounted three-phase electronic energy meters are widely used in construction sites, water treatment plants and municipal engineering equipment. Anti-interference design ensures stable metering under unstable power supply environment, meeting public engineering power measurement standards.

| FAQ |
Q: What communication methods do your smart energy meters support?
A: Standard version reserves RS485 Modbus-RTU port to connect PLC and monitoring host. 4G wireless optional model transmits data to cloud platform without wiring, supporting remote top-up, power cut and real-time data query, two communication ways for customer selection.
Q: Is the metering data safe from tampering?
A: The meter is equipped with transparent anti-theft shell and seal lock, internal data storage chip retains power consumption records for over 10 years even after power failure. Any shell disassembly will trigger tamper alarm and record operation log automatically.
Q: Can I customize meter functions and printed LOGO for bulk orders?
A: We support OEM customization: preset alarm balance value, adjust data upload frequency, print customer brand LOGO on shell and LCD startup screen. All customized meters still pass official metering verification and CE certification.
Q: What's the difference between DIN rail meter and wall-mounted meter?
A: DIN rail energy meter is mini-sized for installation inside distribution cabinets, suitable for factory workshop sub-metering. Wall-mounted meter has larger LCD screen, mainly for household and rental apartment single-user power measurement with card prepayment function.
