| Technical Specifications |
| Environmental conditions |
Operating temperature |
–40°C to +65°C |
| (When the ambient temperature ranges from –33°C to +55°C, this product 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, this product starts properly after the AC power supply is connected. There is no requirement for the output voltage waveform at startup.) |
| Transportation temperature |
–40°C to +70°C |

–40°C to +70°C |
| Operating humidity |
5%–95% RH (non-condensing) |
| Transportation humidity |
5%–95% RH (non-condensing) |
| Storage humidity |
