| AC surge protection | Nominal surge discharge current: 30 kA (8/20 µs), five times respectively in the
positive and negative directions |
||
| 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 55-65°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.) |
