• Antminer S21 Hyd., S21+ Hyd., S21e Hyd., S21 XP Hyd., S21e XP Hyd., S21 XP+ Hyd.
• Antminer S19 XP Hyd., S19 XP+ Hyd., S19 Pro+ Hyd., T19 Pro Hyd.
• Antminer S23 Hyd.

Specifications

• Main output (OUT1): 17–21.6 V DC, 300 A rated, 6500 W rated (380 V input)
• Auxiliary output (OUT2): 12.3 V DC (12.2–12.4 V), 1 A
• Input: 380–415 V AC, 50–60 Hz; power factor >0.99 at full load
• Protection: output short circuit, overheat, output over-current (300–350 A), low input voltage (<304 V AC)
• Cooling: water; inlet temperature 20–35 °C, flow 8 L/min, pressure <3.5 bar
• Dimensions: 320 x 179 x 63 mm; net weight 5 kg
• Operating environment: -20 to 45 °C, 20–90 % RH non-condensing, altitude below 2000 m

Notes

• Bitmain advises updating the miner to its latest firmware after replacing the power supply.
• Bitmain states that one miner model can be compatible with several APW111721 versions (a to d), but the versions are not always interchangeable; check the model and version on the existing unit before replacing it.
• Installation must be carried out by a qualified electrician to local code.
