Qingdao United Estates Limited for the supply of electrical equipment transformers, Germany BLOCK, BLOCK motor filter unit, BLOCK control transformer, BLOCK sine filter, BLOCK power, BLOCK reactor, and other products. 
 BLOCK Transformers: BLOCK transformer is to transform AC voltage, current and impedance of the device, when the primary coil with alternating current, the core (or cores) will be generated in the exchange of flux, the secondary coil induces a voltage (or current). 
 BLOCK transformer from the core (or core) and the coils, there are two or more coil windings, in which power supply is called the primary coil winding, and the rest is called the secondary coil winding. Control transformer and there is no difference between ordinary transformer theory, but for different purposes.
