Operating Conditions
1、The altitude does not exceed 2000 meters.
2、The upper limit of ambient air temperature shall not exceed +40℃.
3、The average ambient air temperature for 24h does not exceed +35℃.
4、The lower limit of ambient air temperature is not less than -5℃.
5、The relative humidity of air is less than 90%.
6、The ambient air does not contain gases or dust that corrode metals and destroy insulation.
7、In use, it is necessary to prevent bumping and violent vibration, and prevent the erosion of water, rain and snow.
8、The power supply voltage waveform is similar to a sine wave.

1、Transformers are divided into different specifications according to their capacity and voltage, but they are single-phase multi-winding, open-type transformers with the first stage separately wound.
2、The transformer coil is generally multi-layer winding type, and also has the form of multi-winding and multi-tapped.
3、When the secondary of the transformer has only one winding, it can bear all the rated capacity; If the secondary has more than one winding, each winding should load the corresponding load according to the allocated capacity.
