Easy DIN rail installation! The DTSD1352 is suitable for various green energy metering needs

I. Matching Green Energy Demands Under the "Dual Carbon" Context

With the deepening implementation of the "dual carbon" strategy, green energy scenarios such as distributed photovoltaics, industrial and commercial energy storage, and zero-carbon industrial parks are experiencing rapid development. However, in the process of project implementation, issues such as reverse power transmission, insufficient metering accuracy, and data silos remain core pain points restricting the safe and compliant operation of projects.

Acrel DTSD1352 rail-mounted anti-backflow smart three-phase meter was designed to address these pain points. It serves as both a safety guardian for distributed photovoltaic grid connection and the metering brain for industrial and commercial energy storage and zero-carbon parks, providing a solid guarantee for the metering of every kilowatt-hour of green electricity and the clear accounting of every penny of revenue.

II. Comprehensive Coverage of Core Scenarios, Adapting to Diverse Needs

1. Distributed PV Grid Connection: Strengthening the Grid Security Defense Line In scenarios with a high proportion of distributed PV grid connection, when the PV power generation exceeds the local load, reverse power flow can easily occur, potentially leading to grid voltage exceeding limits, increased line losses, and protection malfunctions. The DTSD1352 monitors the power flow direction at the grid connection point in real time. Once reverse flow is detected, it can quickly trigger a control signal, linking the inverter for adjustment, eliminating the risk of backflow at the source. Even in the event of a communication interruption, its independent local anti-reverse flow function can still operate normally, safeguarding the last line of defense for grid safety.

2. Industrial and Commercial Energy Storage: Unlocking Peak-Valley Arbitrage and Demand Management In the construction of zero-carbon industrial parks, industrial and commercial energy storage is the core equipment for achieving "peak shaving and valley filling" and improving green electricity consumption. Accurate metering is the key foundation for maximizing the economic benefits of energy storage projects. The DTSD1352 supports bidirectional metering, clearly recording the charging and discharging power of the energy storage system, providing a reliable basis for energy storage efficiency calculation. It also supports metering with multiple rates for 8 and 14 time zones, adapting to complex time-of-use pricing policies in various regions, making peak-valley arbitrage based on "charging during off-peak hours and discharging during peak hours" a reliable strategy. Its demand monitoring function can also provide data support for the EMS system, helping the park smooth its power curve and effectively reduce demand-related electricity costs.

3. Photovoltaic Energy Storage System for Communication Base Stations: Dual Guarantee of Compliance and Energy Saving. As critical infrastructure, communication base stations have high requirements for power supply stability and security. When equipped with photovoltaic energy storage systems, it is necessary to meet the compliance requirements for anti-reverse current and reduce high electricity costs through peak-valley arbitrage. The DTSD1352 power measurement refresh rate can reach 100 milliseconds, which can quickly identify reverse current and link it for control, meeting the compliance requirements of standards such as GB/T 43526-2023. At the same time, with its powerful multi-rate metering capability, it can count the charging and discharging power at different times, helping base stations to achieve "storage during off-peak hours and discharge during peak hours", significantly reducing electricity costs.

III. Core Technology Enables Enhanced Quality High-precision metering achieves active energy accuracy up to 0.5S level, ensuring reliable and accurate data for revenue calculation and carbon emission statistics.

Flexible configuration of thresholds, delays, and other parameters allows for flexible adjustment based on transformer capacity, line impedance, and other site conditions, adapting to diverse application scenarios.

Convenient installation utilizes a standard DIN 35mm DIN rail design, making it compact and particularly suitable for space-constrained environments such as distribution boxes and photovoltaic grid-connected cabinets.

Rich functionality integrates three-phase electrical parameter measurement, demand statistics, event logging, switch input/output, and RS485 communication, enabling seamless integration with various SCADA and energy management systems.

IV. Authoritative Certifications Ensure Full Quality Control: Acrel DTSD1352, with its superior performance and stable quality, has passed multiple authoritative certifications, including:

V. Green Empowerment: Accurately Protecting Every Unit of Electricity. Ensuring every unit of green electricity is accounted for and every penny of revenue is traceable. Acrel DTSD1352 Anti-Reverse Current Smart Three-Phase Meter safeguards safety through metering and empowers green development through intelligent control. It is an indispensable and reliable choice for distributed photovoltaic, industrial and commercial energy storage, and zero-carbon park construction.
