Tech Specs
| Technical Specifications | ||
| Environmental specifications | Operating temperature | –40°C to +65°C |
| (When the ambient temperature ranges from –33°C to +55°C, the power system works properly. When the ambient temperature ranges from 55°C to 65°C, the output power linearly derates by 20%. When the ambient temperature is –40°C, the power system can start properly after the AC power supply is connected. There is no requirement on the output voltage waveform at startup.) | ||
