Acrel's Multi-Circuit AC/DC Energy Metering Solution For Data Center

Acrel’s Dual-Core Solution: DTSD1352-4S & AMC16L-DETT Meters Transform Telecom Tower Energy Monitoring

As 5G networks expand and telecom infrastructure grows more complex, tower operators face pressing demands for precise energy monitoring, cost optimization, and compliance with global efficiency regulations. Acrel Co., Ltd., a leading enterprise microgrid solution provider, addresses this challenge with a tailored dual-core solution—combining the 4-circuit AC energy meter DTSD1352-4S and 6-circuit DC energy meter AMC16L-DETT. This integrated system delivers end-to-end energy visibility for telecom towers, covering everything from grid input to core communication loads, and empowering operators with data-driven insights to enhance efficiency and sustainability.

The Dual-Core Solution: AC/DC Coverage for Comprehensive Monitoring

Acrel’s solution is built around two specialized meters, designed to work in tandem to eliminate energy blind spots in telecom towers—where AC power fuels infrastructure (grid, generators, air conditioners) and DC power powers critical communication equipment (transceivers, batteries, PV systems).

DTSD1352-4S: 4-Circuit AC Meter for Infrastructure Monitoring

Engineered for the unique demands of telecom tower AC systems, the DTSD1352-4S is a compact, high-performance meter that simplifies multi-point monitoring:

4-Circuit Integration: Monitors up to 4 AC circuits in a single DIN-rail device, ideal for tracking grid input, backup generator output, air conditioners, and lighting—all key non-core loads in telecom towers.
Superior Accuracy: Boasts Class 0.5 accuracy for voltage and current, Class 1 for active energy, and ±1% accuracy for 2-31st harmonics. Ensures reliable data for billing, cost allocation, and power quality optimization.
Robust Compatibility: Works with split-core current transformers (up to 600A) for non-intrusive installation, supporting retrofits without disrupting existing operations. Complies with international (Modbus-RTU) and telecom industry (YD/T 1363.3) protocols for seamless integration with tower monitoring systems.
Harsh Environment Resilience: Operates in -20°C to +60°C with surge immunity (Level 4) and strong electromagnetic interference resistance, built to withstand the rigors of outdoor and remote tower sites.
User-Friendly Design: Features dry contact inputs, relay outputs (AC 250V/3A, DC 30V/3A), and RS485 communication (1200~38400 bps), enabling easy configuration and real-time data transmission.

AMC16L-DETT: 6-Circuit DC Meter for Core Load Oversight

For the DC-powered heart of telecom towers, the AMC16L-DETT delivers precise monitoring of critical loads and backup systems:

6-Circuit DC Monitoring: Tailored for 48V telecom systems, tracking power consumption of core equipment (BBUs, RRUs), backup batteries, and PV system outputs—essential for ensuring uninterrupted communication.
Flexible Sensor Compatibility: Works with Hall sensors (50~1000A/5V) selected by current size and cable thickness, with the meter providing dedicated power for sensors (±12V) for simplified installation.
High-Precision Measurement: Offers ±2% accuracy for DC current (above 10% of full scale) and 0.01-unit resolution for voltage, current, power, and energy—critical for optimizing battery life and renewable energy usage.
Proactive Alarming: Built-in alerts for overvoltage, undervoltage, power loss, and module errors, enabling early fault detection to minimize downtime.
Seamless Connectivity: Supports Modbus-RTU and custom protocols via RS485, integrating effortlessly with Acrel’s gateways and cloud platforms for centralized management.

End-to-End System Integration

The DTSD1352-4S and AMC16L-DETT work with Acrel’s AWT200 intelligent gateways and cloud energy management platform to form a complete ecosystem:

Data Aggregation: Gateways collect data from up to 10,000 points, supporting Ethernet, 4G, WiFi, and LoRa for flexible deployment in remote areas with limited connectivity.
Cloud-Based Insights: The platform provides real-time monitoring, energy statistics, PUE calculation, and remote access via web or mobile apps. Enables operators to track consumption trends, identify inefficiencies, and comply with group-level data upload requirements.
Third-Party Interoperability: Integrates with existing tower management systems (e.g., 动环监控，operator infrastructure platforms) through standard protocols, ensuring no disruption to current operations.

Key Benefits for Telecom Tower Operators

Acrel’s dual-core solution addresses the unique pain points of telecom tower energy management:

Space & Cost Savings: Integrated multi-circuit designs reduce the number of meters needed by up to 75%, saving cabinet space and cutting wiring/hardware costs.
Comprehensive Visibility: Covers both AC infrastructure and DC core loads, eliminating energy blind spots and enabling total tower energy accountability.
Simplified Retrofits: Compatible with existing sensors and equipment, supporting “maximize reuse” principles to minimize upgrade costs for legacy towers.
Regulatory Compliance: Aligns with global energy efficiency policies (e.g., China’s Industrial Energy Efficiency Improvement Plan) and operator requirements for PUE monitoring and data reporting.
Proactive Maintenance: Real-time data and alarm functions enable early detection of abnormal consumption or equipment issues, reducing downtime and maintenance costs.

Global Success Stories: Trusted by Leading Operators

Acrel’s DTSD1352-4S and AMC16L-DETT have been widely adopted in telecom tower projects worldwide, delivering proven value:

Domestic Deployments: Partnered with China Unicom for the Henan Energy Consumption Zoning Project, supplying meters for 3,218 access rooms, 232 convergence rooms, and 37 core rooms—achieving 100% monitoring coverage and 15% operational cost reduction. Also integrated into solar-powered tower projects in Sichuan, Anhui, and other regions, monitoring DC-side renewable energy usage.

International Expansion: Deployed in African (Madagascar, Senegal), European (UK), and Southeast Asian (Philippines) towers. Used by operators including Orange, Helios Towers, and Edgepoint, with over 10,000 combined meter sets installed globally.

Tower Company Adoption: Trusted by China Tower, American Tower, and Helios Towers for its reliability, ease of installation, and ability to scale across large tower portfolios.
