BK 1000va Control Transformer 220v to 12v AUTOTRANSFORMER 380V / 220 / 110V
Feature
1). The control transformer can easily obtain the appropriate voltage, and can also change the voltage of the alternating current and change the impedance at the same time.
2). When the design power is not exceeded, the control transformer can also change the current.
3). In different environments, the purpose of the transformer is also different, and it also has the effect of preventing interference.
Structure:
■ Square shape, special plastic connection board and steel copper coil inside.
■ BK series steel copper coils are Cold-rolled Square shape.
■ BKC series steel copper coil are imported material,coil roller into "C" shape,which do effect on reducing noise and consumption.
