| Maximum output power | 24 kW | |
| Electrical Specifications | ||
| AC input | Input system | 220/380 V AC three-phase, four-wire |
| Input voltage | 85–300 V AC | |
| Input frequency | Frequency range: 45–66 Hz; nominal frequency: 50 Hz or 60 Hz | |
| PF | ≥ 0.99 (rated input, full load) | |
| THD | ≤ 10% (Vin = 208 V AC, 220 V AC, 230 V AC; 50%–100% load) | |
| DC output | Output voltage range | –42 V DC to –58 V DC |
| Default output voltage | –53.5 V DC | |
