• Each S19 XP Hyd.: 257 TH/s typical, 5,346 W at the wall, 20.8 J/TH (35 °C coolant inlet)
• Miner supply: 380–415 V, three-phase, 50/60 Hz, 12 A maximum
• Miner size: 410 × 170 × 209 mm; 12.8 kg net
• Miner coolant: 20–40 °C inlet, 8–10 L/min, ≤3.5 bar, OD10 connectors
• Cabinet: 1,260 × 600 × 1,185 mm, 138 kg net; 380–415 V AC three-phase, 63 A
• Cabinet pump: 450 W, 19 m lift
• External cooler: 1,197 × 650 × 1,177 mm, 112 kg net; 750 W fan
