It is suitable for AC circuit of 50~60Hz, widely applied in electronic industry, industrial and mining enterprise, worked as control power supply for usual circuit of machine tool and mechanical equipment and as power supply for safety lighting and indicator lamp.

The primary and secondary windings are winded separately, when the secondary one only has one winding, then it takes on all the rated capacity for transformer.

If the secondary one accompanied with control, lighting and indicator lamp windings, it will be winded respectively according to each winding capacity.

For simplex winding transformer with center tap, all the center taps capacity should be lower than rated capacity of transformer, only the max voltage output terminal can bear the rated capacity.

The transformer can work reliably under the following conditions:

1. Altitude should not exceed 2,500m;

2. Ambient air temperature: -25℃~+ 40℃;

3. Relative humidity: max average relative humidity of the dampest month is 90%;4. Places that are free from severe v ibration or shock;

5. Environment exists without explosive medium, gas or conductive dust hat will erode metal and destroy insulation;

6. Places that are free from rain or snow.

1. Before purchasing, please calculate out the total capacity of electrical appliances that you are using and then choose right transformer, make sure that the transformer will not be burnt during instantaneous starting.

2. This transformer is designed and produced according to national relative standards strictly. When you apply transformers with multi windings (multi control voltagel, please accord to the voltage ratio to addtransformer's capacity proportionally, so that the transformer will not be burnt.

3. Before installing please check the data that on the nameplate carefully to see if the specification is what you need, only after confirmed that you can install and put it into use.

4. After switching on, the iron core and coil of transformer will be heated (but the temperature rise will not exceed 80C), it's a normal phenomenon, once the temperature rise exceeds 80°C, even thereis smoke, please cut the power supply and check the capacity of electrical appliances again.

5. During transportation, try to avoid impact, and far away from damp.

During operation, pay attention to maintaining to ensure the transformer's service life.
