Lexindar APW12 4000W Air-cooled Server Power Supply

SKU CH-2MHE-QC47F

Air-cooled 4000 W server supply with dual 16 A AC inputs, IIC regulation and 230–277 V operation for S19, T19 and S19J series miners

  • Delivers 4000 W to power demanding mining rigs
  • Dual voltage outputs with IIC regulation for precise control
  • Operates on 230 V to 277 V high-voltage mains
  • AC input uses two 16 A ports for higher current tolerance
  • Quiet air-cooled design with 24-hour burn-in validation

High-voltage 4000W server supply

The Lexindar APW12 delivers 4000W through two voltage rails with IIC protocol regulation. It is built for 230V-277V high-voltage circuits and includes dual 16A AC input ports. The unit has undergone 24-hour ageing tests and features internal insulation with solid filter capacitors.

For high-voltage mining rigs only

This supply suits operators running S19, S19PRO, T19, S19J or S19JPRO machines on 230V-277V mains. It is not suited for standard desktop builds or low-voltage circuits. Buyers needing single-rail output or integrated AC cables should look at other units.

Dual 16A AC input with C13 interface

The power supply requires two separate 16A C13 cables with at least 1 mm² copper conductors. No AC cables are included in the box. Verify local voltage and plug standards before purchase.

Questions about this item

How can I confirm the 4000W supply is operating correctly after installation?

Verify that both 16A AC input ports show stable voltage between 230V and 277V, check that the IIC protocol regulation reports normal dual-voltage output, and listen for quiet fan operation under load.

Which cables and accessories are included versus sold separately?

The unit ships with the power supply only; you must supply your own C13-terminated AC input cables with at least 1 mm² copper cross-section to match local plug standards.

How do I decide whether this 4000W model fits my S19 or T19 mining rig?

Match the 4000W rating and 230V–277V input range to your rig’s total power draw; the dual-voltage output and IIC regulation are designed for S19, S19PRO, T19, S19J and S19JPRO units.
