Ethereum: Higher Costs Running Antminer S9 with APW3++ on 220V

As the popularity of cryptocurrencies continues to grow, many miners are looking to upgrade their equipment to stay ahead of the competition. One of the most popular mining rigs on the market is the Antminer S9, and one of its key components is the Advanced Power Washing (APW) unit, which improves its performance.

However, when running Antminer S9s with the Advanced Power Washing (APW)++ unit on 220V, a common problem arises: increased operating costs. In this article, we will delve into the details of why running an Antminer S9 on 220V can be more expensive than running it on 110V.

Understand APW and its Requirements

APW is an advanced power washing system designed to optimize electrical efficiency for mining rigs like the Antminer S9. It is basically an intelligent load management system that adjusts the power of your mining rig based on factors such as voltage, current, and temperature.

The APW++ unit is specifically designed for high-performance applications such as mining. It has advanced algorithms that take into account various parameters to optimize power consumption and energy efficiency. In our experience, running an Antminer S9 on 220V requires the use of an APW++ unit.

Why Higher Voltage Increases Operating Costs

When running your Antminer S9s with an APW++ unit on 220V, several factors contribute to higher operating costs:

• Increased Power Consumption: At 220V, the current drawn by each Antminer S9 is significantly higher than what is required for 110V settings. This increased power consumption increases energy consumption and higher electricity bills.

• Higher Power Factor Correction (PFC) Requirements: The APW++ unit requires a higher PFC rating at 220V, which means it must handle higher voltages and currents. This increases the cost of the module due to increased complexity and higher component costs.

• More advanced power electronics

  

  : The higher voltage also requires more advanced power electronics such as IGBTs (Insulated Gate Bipolar Transistors) and high voltage switches, which come at a higher cost.

110v vs 220v Setup Comparison

To give you a better idea of ​​the differences between running the Antminer S9 on 110v or 220v, let’s look at some rough estimates:

• Running the Antminer S9 on 110v:

+ Electricity cost: $0.05 per hour

+ Energy consumption: around 100-150Wh (depending on the number of units and usage patterns)

+ APW++ unit power consumption: around 20-30% of the total energy consumption due to the higher power consumption on 110v

• Running the Antminer S9 on 220v:

+ Electricity cost: $0.10 per hour (due to the higher power consumption due to increased electricity bills)

+ Energy consumption: around 150-200Wh (depending on the number of units and usage patterns)

+ APW++ unit power consumption: approximately 40-50% of total energy consumption due to even higher power consumption at 220v

Conclusion

In conclusion, running an Antminer S9 with an Advanced Power Washing (APW)++ unit at 220v can indeed increase operating costs compared to a 110v setup. While the APW++ unit is designed to optimize energy efficiency for high-performance applications, the added complexity and component costs come with higher prices.

If you want to reduce your electricity bill without sacrificing performance, it is important to carefully consider your specific power requirements and energy usage patterns before making any decisions.
