How to replace the LP20 aviation plug 4-core female for the APW11 Hydro PSU cord?

LP-20-J04PE-01-022 is a 20A 500VAC 4-pin female power cord connector, also known as the LP20 waterproof aviation plug 4-core female, which is used to replace the faulty plug of Antminer APW11/APW12 Hydro miner power cables. It offers a flexible power connection solution for miners, ensuring stable performance in harsh environments.

Advantages of LP20 aviation plug:

1. High quality: 4U gold-plated connector, real gold plating, strong conductivity, not easy to oxidize, and extended service life.

2. Automatic plugging and unplugging: Allows for simple and fast operation, improving efficiency.

3. Self-locking device: Ensures quick connection in various environments, improving reliability and safety.

4. High Safety: Meets IP67 waterproof, fireproof, and UV0 flame retardant standards, ensuring stable operation in harsh environments.

Faulty power cord connectors can lead to poor circuit connection or open circuits, affecting mining efficiency and increasing electricity costs, ultimately reducing miners' profits. Therefore, it is crucial to replace faulty connectors promptly to avoid safety hazards and ensure stable equipment operation.

Replacing steps for the LP20 4-pin female connector:

1. After disconnecting the power to the miner, unplug the power cord. Press the "Push" button of the faulty PSU cable connector to unlock it, then unscrew the tightening nut, then carefully pull the cable out of the connector.

2. Use a wire stripper to carefully strip the insulation from the cable, exposing the four internal leads (leave an appropriate length for connecting the connector later). Strip about 5-10mm of insulation from the end of each wire to expose the copper core.

3. Inspect the new LP20 4-pin aviation connector if it is intact, then disassemble it. Pass the four leads through its components and solder the copper cores to the corresponding positions on the connector with a soldering iron. Tighten the plug's tightening nut to complete the replacement.

4. Connect the 4-pin plug of the power cord to the miner's power interface and the other end to the air switch. Power on the miner to observe its operating status, ensuring a successful replacement of the power cord connector.

With its superior performance and simple operation, the LP20 aviation connector has become the best replacement option for the APW11/APW12 Hydro PSU cable. Promptly replacing the faulty one can restore the miner's normal operation to avoid further downtime losses.
