How Does Antminer T21 PDU125-12AC1 Support Both Three-Phase and Single-Phase Configurations?
In the world of cryptocurrency mining, efficient power management is critical to maximizing profitability and ensuring operational stability. The Antminer T21 PDU125-12AC1 stands out as a high-performance power distribution unit (PDU) designed to meet the demanding needs of modern mining operations. One of its most notable features is its ability to support both three-phase and single-phase power configurations seamlessly. This flexibility makes it an invaluable asset for mining operators who need to adapt to diverse setups or scale their operations efficiently. In this article, we’ll explore how the Antminer T21 PDU125-12AC1 achieves this dual-configuration capability, its practical applications, and the advantages it brings to cryptocurrency mining operations.
Product Introduction: Antminer T21 PDU125-12AC1
The Antminer T21 PDU125-12AC1 is an industrial-grade power distribution unit engineered specifically for cryptocurrency mining. With a robust output capacity of 85KW, it is designed to handle the high power demands of large-scale mining farms. Its versatility lies in its ability to support a wide input voltage range of 346-480V AC in a three-phase + neutral + protective earth configuration, making it compatible with various power infrastructures.
The PDU features 12 output ports with 6-pin connectors, along with one AC30 3-in-1 multifunctional port, providing flexible power distribution across multiple mining devices. Its compact dimensions (1100mm × 125mm × 70mm) and lightweight design (5.6KG) make it easy to install and maintain, even in space-constrained environments. Built with industrial-grade materials, including 252g of copper and 502g of aluminum, the PDU ensures exceptional durability and efficient thermal management.
Safety is a top priority, with features like IP20 protection, a 125A/4P input current specification, and a 500V voltage withstand capacity. These safeguards protect against overloads and short circuits, ensuring the safety of both mining equipment and facility infrastructure. The PDU is optimized for harsh mining environments, operating reliably at temperatures ranging from -20°C to 40°C and relative humidity levels of 5%-90% without condensation.
Flexible Power Configuration: A Key Advantage
One of the standout features of the Antminer T21 PDU125-12AC1 is its ability to support both three-phase and single-phase power configurations. This flexibility is crucial for mining operators who may need to adapt to different power setups or expand their operations without requiring significant infrastructure changes.
How It Works
The PDU’s dual-voltage output capability allows it to operate in two distinct modes:
- Three-Phase Configuration: In this setup, the PDU uses three-phase power (346-480V AC), which is ideal for large-scale mining farms. Three-phase power is more efficient for distributing high loads, as it provides a balanced and consistent power supply across all connected devices. This configuration minimizes energy loss and ensures stable performance, even under heavy workloads.
- Single-Phase Configuration: For smaller setups or locations where three-phase power is unavailable, the PDU can operate in single-phase mode (200-227V AC). This flexibility allows mining operators to utilize the PDU in a broader range of environments, from home-based mining rigs to smaller data centers.
The PDU achieves this versatility through its sophisticated design and robust internal components. Its 12 output ports are engineered to deliver consistent power distribution, regardless of the configuration used. Additionally, the AC30 3-in-1 multifunctional port enhances flexibility by supporting various connection types.
Practical Applications
The ability to switch between three-phase and single-phase configurations makes the Antminer T21 PDU125-12AC1 highly adaptable to different mining scenarios:
- Large-Scale Mining Farms: In facilities with three-phase power infrastructure, the PDU maximizes efficiency and power delivery, ensuring uninterrupted operation across hundreds or thousands of mining devices.
- Smaller Operations: For smaller setups or locations with limited power infrastructure, the single-phase configuration provides a viable solution without compromising performance.
- Future Expansion: Mining operators planning to scale their operations can leverage the PDU’s dual-configuration capability to transition seamlessly from single-phase to three-phase setups as their needs grow.
