1. Industrial-Grade Circuit Protection for Overload and Short Circuits

One of the most critical safety aspects of any mining PDU is its ability to prevent electrical hazards such as overloads and short circuits. The Antminer T21 PDU125-12AC1 is equipped with a 125A circuit breaker that automatically cuts off power in case of excessive current draw, protecting both the PDU and connected mining rigs from damage.

Key Safety Mechanisms:

• 500V Voltage Withstand Capacity – Ensures the PDU can handle voltage spikes without failure.
• Three-Phase + Neutral + Protective Earth Configuration – Provides balanced power distribution and reduces the risk of electrical faults.
• Short-Circuit Protection – Prevents catastrophic failures that could result from wiring issues or sudden power surges.

This level of protection is crucial in mining farms where multiple high-power ASICs operate simultaneously, often pushing electrical systems to their limits.

2. High-Temperature and Humidity Resistance for Harsh Environments

Mining farms often operate in environments with fluctuating temperatures and humidity levels. The Antminer T21 PDU125-12AC1 is built to withstand these challenges, featuring:

• Operating Temperature Range: -20°C to 40°C – Ensures stable performance in both cold and hot climates.
• Humidity Resistance: 5%–90% (Non-Condensing) – Prevents moisture-related corrosion and electrical failures.
• High-Altitude Compatibility (Up to 2000m) – Maintains efficiency even in elevated locations where air density affects cooling.

These specifications make the PDU suitable for deployment in various geographic conditions, from underground mining facilities to open-air data centers.

3. IP20 Protection Against Dust and Accidental Contact

While not fully waterproof, the IP20-rated enclosure provides essential protection against:

• Dust and Particulate Ingress – Minimizes the risk of internal component contamination.
• Accidental Finger Contact – Prevents electrical shocks from exposed terminals.

This is particularly important in mining farms where dust accumulation from cooling fans and environmental factors can degrade electrical components over time.

4. Robust Build Quality with Industrial-Grade Materials

The Antminer T21 PDU125-12AC1 is constructed using 252g of copper and 502g of aluminum, ensuring:

• Superior Heat Dissipation – Reduces overheating risks during prolonged high-load operation.
• Long-Term Durability – Resists wear and tear in 24/7 mining environments.
• Stable Power Transmission – Minimizes resistance and voltage drops across connections.

Unlike consumer-grade PDUs, this industrial-strength design ensures years of reliable service with minimal maintenance.

5. Flexible and Secure Power Distribution with Multiple Output Ports

The PDU features 12 output ports with 6-pin connectors and an additional AC30 3-in-1 multifunctional port, allowing for:

• Three-Phase (346-480V) and Single-Phase (200-227V) Configurations – Supports different mining hardware setups.
• Balanced Load Distribution – Prevents overloading on any single circuit.
• Easy Scalability – Enables expansion without requiring additional PDUs.

This flexibility is essential for large farms that may need to reconfigure power distribution as they upgrade or expand operations.

6. Compliance with Global Electrical Standards

The Antminer T21 PDU125-12AC1 is designed to meet international power standards, including:

• 50/60Hz Frequency Compatibility – Works seamlessly in different regions.
• Wide Input Voltage Range (346-480V AC) – Adapts to varying grid conditions.

This global compatibility ensures that mining farms can deploy the PDU in multiple locations without compatibility concerns.
