JBK series machine tool control transformer for AC 50-60Hz,input voltage less than 660V circuit,as the various types of machine tools,Machinery and equipment to control the general electric power supply,local lighting power.This series is the other control substation transformer replacement products,using imported materials and advanced technology of manufacturing .with the work Be reliable.the low energy,small size,wait until the system point of wide applicability.
The biggest characteristic of this kind of transformer is that it is small and beautiful, can work effectively for a long time at rated load, and has high temperature resistance and electrical strength.
The altitude is not more than 3000m.
The upper limit of ambient medium temperature shall not exceed +40℃, and the lower limit shall not be lower than -8℃.
The relative humidity of the air is not more than 70%(when the temperature is 25℃). In a medium without explosion hazard and free of gases or conductive dust sufficient to corrode metal and destroy insulation.
Where there is no significant shaking or shock vibration.
A place protected from rain and snow.
What is the control transformer
The control transformer is mainly suitable for AC 50Hz(or 60Hz), voltage 1000V and below circuit, can work continuously for a long time under rated load. Usually used in machine tools, mechanical equipment as electrical control lighting and indicator power.
The control transformer is a small dry type transformer. Commonly used as a local lighting power source, signal lamp or indicator power supply, in electrical equipment as a control circuit power supply.
The control transformer works on the principle of electromagnetic induction. A transformer has two sets of coils. Primary coil and secondary coil. The secondary coil is outside the primary coil. When the primary coil is connected with alternating current, the transformer core generates alternating magnetic field, and the secondary coil generates induced electromotive force. The coil turns ratio of Satons transformer is equal to the voltage ratio.
