1. Scope of application

Applicable to 50-60Hz AC circuit, it is widely used in electronics industry or industrial and mining enterprises, general current control power supply for machine tools and mechanical equipment, power supply for safety lighting and indicator light.

2. Model and its meaning

Technical characteristics

The primary and secondary windings are separately wound. When there is only one winding in the secondary, it bears the full rated capacity of the transformer. If the secondary has both control, illumination and indicator windings, it is distributed according to the distribution of each winding capacity. The transformer with intermediate taps has a middle tap capacity which is smaller than the rated capacity of the transformer. Only the highest voltage output can bear the rated capacity.

2. Use environment

The transformer works reliably under the following conditions:

1) The altitude does not exceed 2500m;

2) ambient air temperature; the maximum does not exceed 40 ° C, the minimum is not lower than -25 ° C;

3) Relative humidity of air: the average maximum relative humidity of the wettest month is 90%;

4) Where there is no severe vibration and impulsivity;

5) In a medium free of explosion hazard, and there is no place in the medium that is sufficient to corrode metal and destroy insulating gas and conductive dust;

6) Locations that are not affected by rain or snow.
