Công tơ điện thông minh phục vụ đối tượng nào?

Doanh nghiệp, khu công nghiệp, hạ tầng và SI cần đo đếm + truyền dữ liệu gắn hệ giám sát. Không định vị bán công tơ hộ gia đình lẻ hay thay thế công tơ EVN dân dụng. Brief điểm đo và giao thức hệ nhận dữ liệu là đầu vào chính.

Cần thông tin gì để bắt đầu?

Điểm đo (1 pha/3 pha, tải ước tính), chu kỳ ghi, giao thức hoặc hệ giám sát đích, điều kiện lắp đặt. Chưa cần schematic đầy đủ. Chúng tôi đề xuất phương án và pilot điểm đo đại diện trước khi nhân rộng.

Hỗ trợ giao thức truyền dữ liệu nào?

Tùy brief: Modbus, MQTT, hoặc cổng mà hệ giám sát đang dùng. Không có một danh mục cố định trên web vì phụ thuộc hạ tầng khách. Nêu hệ đích giúp chốt phạm vi nhanh hơn tên chip.

Có làm chứng nhận đo đếm pháp lý không?

Chứng nhận pháp lý (nếu cần) là hạng mục riêng theo thị trường và phụ thuộc phòng lab/đối tác — không mặc định trong mọi dự án R&D. Nhiều pilot nội bộ chỉ cần độ chính xác kỹ thuật theo brief. Chúng tôi nói rõ phần nào thuộc chứng nhận trước khi báo phạm vi.

Có bán công tơ dân dụng / DIY solar nhà ở không?

Không. Phạm vi hub này là đo đếm B2B/hạ tầng gắn hệ giám sát — không bán lẻ công tơ nhà ở, DIY năng lượng mặt trời hộ gia đình, hay thay thế công tơ điện lực dân dụng. Nếu bạn cần đo đếm doanh nghiệp/hạ tầng, hãy mô tả điểm đo.

Engagement Scenarios

When Enterprises Partner With DeviceLab For This Service

We collaborate with forward-thinking enterprises, OEMs, and product innovators navigating critical hardware challenges.

Commercial Facility & Tenant Submetering

Property managers needing accurate, tamper-proof submetering to calculate individual tenant electricity billing without manual meter readings.

Industrial Energy Management & ISO 50001

Manufacturing plants tracking energy consumption per production line, calculating carbon footprints, and identifying peak demand penalties.

Power Quality & Equipment Health Monitoring

Continuous monitoring of voltage sags, power factor (cos φ), Total Harmonic Distortion (THD), and neutral currents to prevent motor and transformer burnout.

Technical Scope

Core Engineering Capabilities & Specifications

Deep engineering competence verified by laboratory instrumentation and compliant with global manufacturing standards.

✓ High-Precision Energy Measurement

Dedicated metrology DSP chips delivering Class 0.5S (active energy) and Class 2.0 (reactive energy) measurement compliant with IEC 62053-22.

✓ Comprehensive Electrical Parameter Sampling

True RMS measurement of Voltage (V), Current (A), Active Power (kW), Reactive Power (kvar), Apparent Power (kVA), Power Factor (PF), and Frequency (Hz).

✓ Multi-Channel High-Density Submetering

Compact modular designs monitoring multiple 3-phase circuits or single-phase branches within a single electrical distribution panel.

✓ Flexible Communication Telemetry

Standard RS485 Modbus RTU interface with optional wireless modules: 4G LTE Cat-1, LoRaWAN, Wi-Fi, and Ethernet Modbus TCP.

✓ Power Quality & Harmonic Analysis

Harmonic distortion measurement up to the 31st harmonic order, voltage unbalance detection, and event logging for power surges and dropouts.

✓ Seamless EMS / BMS Integration

Pre-mapped Modbus register tables and open REST / MQTT APIs for direct integration into Building Management Systems and Energy Management Software.

Comparative Advantage

Engineering Partnership vs. Freelancers & Generic Agencies

Commercial hardware cannot be trusted to amateur experimentation. Why B2B enterprises choose DeviceLab.

Freelancers / Fragmented Contractors	DeviceLab Engineering Partner
✕ Requires manual monthly clipboard meter reading prone to human error and billing disputes.	✓ Automated digital telemetry transmits readings continuously to cloud or SCADA servers.
✕ Zero real-time data: unable to identify peak demand spikes or equipment running unnecessarily.	✓ Granular 1-minute to 15-minute load profiling to optimize peak tariff consumption.
✕ No power quality insights: voltage sags and harmonics remain undetected until equipment fails.	✓ Continuous power quality surveillance protecting sensitive industrial machinery.
✕ Cannot automate tenant billing or integrate with digital software platforms.	✓ Direct API integration with accounting, tenant billing, and ISO 50001 energy systems.

Engineering Clarifications

Frequently Asked Questions

Direct answers to commercial, technical, and operational questions from prospective hardware partners.

Can smart meters be retrofitted without shutting down electrical power? +

Yes. By utilizing split-core Current Transformers (CTs), we install metering sensors around existing power cables without disconnecting busbars or shutting down critical facility power.

Can we export meter data to our own in-house software or database? +

Yes. Our smart meters utilize standard open Modbus RTU/TCP protocols with published register tables, allowing direct extraction into any database, SCADA, or custom software with no proprietary lock-in.
