Bitmain Antminer Power Supply APW3++ User Manual

1. Introduction

This manual provides essential information for the safe and efficient use of your Bitmain Antminer Power Supply APW3++. Please read this manual thoroughly before installation and operation to ensure proper functionality and longevity of the unit.

The APW3++ power supply is designed for compatibility with Antminer models including L3+, S9, T9, and D3.

2. Safety Information

• Always ensure the power supply is disconnected from the main power source before performing any installation, maintenance, or troubleshooting.
• Use only a standard PC power cable (C13 type). For high wattage operation (e.g., 1600W at 220V), a 14-gauge or higher rated power cord is recommended to prevent overheating and ensure safety. Do not use a standard computer plug for high-power applications.
• Ensure adequate ventilation around the power supply to prevent overheating. Do not block air vents.
• The APW3++ power supply does not feature an integrated power switch or fuse protection. Powering the unit on or off requires connecting or disconnecting the power cable. A slight spark may occur during connection or disconnection, which is normal due to the absence of a switch. Exercise caution.
• Avoid exposing the unit to moisture, dust, or extreme temperatures.
• Do not attempt to open or modify the power supply unit. This will void any warranty and may pose a safety risk.

3. Product Features

• Designed for AntMiner L3+, S9, T9, and D3 models.
• Equipped with ten 6-pin PCIe connectors for multiple device connections.
• Maximum output of 1200W at 110V-120V input.
• Maximum output of 1600W at 220V-240V input.
• Compact ATX form factor.
• Air cooling method.

4. Setup Instructions

1. Unpack the Power Supply: Carefully remove the APW3++ power supply from its packaging. Inspect for any visible damage.
2. Prepare the Environment: Ensure the installation area is clean, dry, and has adequate airflow. Avoid confined spaces.
3. Connect PCIe Cables: Connect the ten 6-pin PCIe power connectors from the APW3++ to the corresponding power input ports on your Antminer device(s). Ensure all connections are secure.
4. Connect AC Power Cable: Insert a compatible C13 power cable (not included) into the AC input socket on the rear of the power supply.

5. Connect to Wall Outlet: Plug the other end of the AC power cable into a grounded electrical outlet. Ensure the outlet provides the correct voltage (110-120V or 220-240V) for your intended operation.

5. Operating Instructions

• Power On: Once all connections are secure and the AC power cable is plugged into the wall outlet, the power supply will activate. There is no separate power switch.
• Voltage Considerations: The power supply automatically adjusts to the input voltage. For maximum output (1600W), a 220V-240V input is required. At 110V-120V, the maximum output is 1200W. Ensure your electrical infrastructure supports the desired wattage.
• Noise Level: The power supply operates with a cooling fan. While the PSU itself has a moderate noise level, the connected Antminer device (e.g., S9) typically produces significantly higher noise levels (e.g., 85-90 dB).
• Power Off: To power off the unit, safely disconnect the AC power cable from the wall outlet.

6. Maintenance

• Dust Removal: Regularly inspect the power supply and its fan for dust accumulation. Use compressed air to gently clean the fan and vents to ensure optimal airflow and prevent overheating.
• Airflow: Ensure the area around the power supply remains clear of obstructions to allow for proper air circulation.
• Fan Check: Periodically check the cooling fan for proper operation. A non-functional fan can lead to rapid overheating and damage to the power supply.

7. Troubleshooting

• Power Supply Not Turning On:
  • Verify that the AC power cable is securely connected to both the power supply and a functional wall outlet.
  • Check the wall outlet with another device to confirm it is receiving power.
  • Ensure the power cable itself is not damaged.
• Overheating:
  • Check for obstructions around the power supply's air vents.
  • Clean any dust accumulation from the fan and vents.
  • Verify that the internal cooling fan is operating correctly. A faulty fan can cause rapid temperature increases.
• Unit Not Providing Full Power:
  • Confirm that the input voltage matches the requirements for the desired output (e.g., 220-240V for 1600W).
  • Ensure the power cable used is of adequate gauge (e.g., 14-gauge or higher for 1600W operation).
• Spark When Connecting/Disconnecting Power:
  • This is a normal occurrence due to the absence of a power switch. Exercise caution when plugging in or unplugging the unit.
