HG-20 Aviation Power Connector – 4-Pin APW11 / APW12 Hydro PSU Plug

HG-20 Aviation Power Connector – Generic 4-Pin Plug for Bitmain APW11 / APW12 Hydro PSU

The HG-20 is a 4-pin aviation-grade power connector rated at 20A / 500VAC, designed as a generic equivalent of the LP-20 connector fitted to Bitmain APW11 and APW12 hydro cooling power supplies. The HG-20 shares the same 20 mm aviation-plug standard — same housing diameter, same pin layout, same electrical rating — so it drops in as a direct mechanical and electrical replacement at a more accessible price point. Use it to replace a damaged plug without replacing the entire power cord, restoring reliable power delivery to water-cooled Antminer systems for a fraction of the cost of a full cord swap.

Generic Equivalent — Same Function, Same Fitment

Aviation plugs in the 20 mm size class follow a common industry standard: a 4-pin configuration rated for 20 A / 500 VAC, with interchangeable housing geometry across manufacturers. The HG-20 is produced to this standard alongside other variants such as the LP-20 — same pin layout, same secure-fit collar, same load capability. For a repair shop or a mining-farm spares cupboard, the HG-20 is the right call when you need the connector function without the brand premium: same physical fit, same electrical behaviour, lower per-unit cost, factory-direct from China.

Why Replace Just the Connector

Hydro PSU power cords are expensive and often difficult to source as complete assemblies. When the plug itself fails — corroded pins, cracked housing, loose fit after vibration — replacing only the connector is faster and cheaper than replacing the entire cord. The HG-20's aviation-grade construction provides a secure, vibration-resistant connection that handles the sustained high-current loads typical of water-cooled mining facilities, with the same dependability profile as the brand-name original.

Installation

Power off the PSU and unplug the cord from mains. Cut the damaged connector off the existing power cord, leaving enough length to strip and prepare the wire ends cleanly. Connect the wires to the HG-20 terminal pins following the correct pinout — confirm the wire order against the original LP-20 it is replacing before crimping. Secure the housing, plug into the PSU, and verify a tight, fully seated connection before re-energising. A test under no-load is always worth a minute before reinstating full mining duty.

When to Choose HG-20 vs LP-20

Both connectors do the same job and fit the same APW11 / APW12 sockets. Choose the HG-20 generic when you are stocking spare connectors for fleet maintenance, replacing a plug on a budget, or supplying repair shops that prefer cost-effective parts without a brand premium. Choose the LP-20 when an end customer specifically requests the branded part, when an OEM warranty audit may apply, or when buying single units where the price gap is negligible. Both are stocked together so you can pick the option that matches your repair scenario.
