Detail Parameters
| Parameter Classification | Parameter Item | Parameter Value |
|---|
| Normal Operating Conditions and Installation Conditions | 3.1 | Elevation does not exceed 2000m. |
| 3.2 | The upper limit of ambient air temperature is 40℃, the lower limit of ambient air temperature is -5℃ (if the user needs to use it in an environment above 40℃ or below -5℃, it needs to be specified at the time of ordering, special customization). |
| 3.3 | When the maximum temperature is 40℃, the relative humidity of the air does not exceed 50%, and at lower temperatures, higher relative humidity is allowed, for example, up to 90% at 20℃. Special measures should be taken for occasional condensation caused by temperature changes. |
| 3.4 | The installation environment should be well-ventilated, free from dirt, corrosive gases, dust, flammable media, combustible materials, and flammable gases; have protection against rain, water, and snow, and no steam. |
| 3.5 | The installation location has no vibration and impact. |
| 3.6 | The power supply voltage waveform is a sine wave, the total harmonic content of the input power supply voltage is no more than 5%, even harmonic content is no more than 1%, and the total harmonic content of the load current is no more than 5%. |
