2. Product Introduction
The rated capacity of this single phase transformer is 5KVA. The input voltage and output voltage are 380V and 220V respectivly. Certainly, it could be customized according to your request.
This transformer is designed with double windings. There are various advantages of double windings design: sound heat dissipation, strong electricity conductivity, better load-bearing capability etc. In the past, the single phase transformer is designed with only one winding. Later, Ewen developed such a new style single phase transformer with more than 5KVA capacity.
3. Product Features
| Delicate design | Double windings design makes the transformer more delicate. |
| Strong load bearing capability | The working efficiency of this transformer is up to 98%. The load-bearing capability is very strong. |
| Low no-load loss | When there is no load, the no-load loss is negligible. |
| High insulation class | The normal insulation class is F. It could be customized as H or even higher class. |
| Sound heat dissipation | The double windings design facilitates better heat dissipation. |
| Quick reaction speed | The transformer reacts quickly to change the primary voltage to the secondary one, usually within one second. |
