2017-08-02 11:16:02   COMMENT:0 HITS:
1. operating environment temperature is -40, ~+85, relative humidity is not more than 95% (25 degrees centigrade), the altitude is not more than 1000m;
2. the rated voltage is 9600V, the waveform of the power supply should be sine wave, and the distortion coefficient of the waveform is not greater than 5%;
3. there is no serious pollution in the atmosphere in the place of use.
4. there is no serious vibration and bump in use place;
5. there should be no external strong magnetic field which has nothing to do with work.
