What should be paid attention to when using quality control transformer?
When using the control transformer, two points should be paid attention to: one is the power of the transformer, and the other is correct wiring. The total power of the load connected to the secondary side (secondary) shall not exceed the power of the control transformer, and short circuit is not allowed. Otherwise, its temperature will be too high, and it will be burnt in severe cases. The primary and secondary (i.e. primary and secondary) wiring of the control transformer must not be wrongly connected, especially the primary side wiring.

The voltage value to be connected to the primary side is marked on its terminal. It is absolutely not allowed to connect the 380 V power line to the 220 V terminal, but it is possible to connect the 220 V power line to the 380 V terminal. At this time, all output voltages on the secondary side will be reduced by 1.73 times. The secondary side load should be connected to the corresponding terminal according to its rated voltage value, for example, the indicator light of 6.3 V should be connected to the 6.3 V terminal, the 36 V light bulb of the machine tool should be connected to the 36 V terminal, and the 127 V light bulb should be connected to the 36 V terminal. The machine tool AC contactor coil should be connected to the 127 V terminal.

What are the characteristics and functions of BK series transformers?
BK series transformers can be divided into shell type according to structure, and vertical type according to installation method.
BK series quality control transformer is a new type of variable voltage power supply developed by our country by absorbing foreign products of the same level. It has the characteristics of small size, safe and reliable wiring, high protection level, good performance, etc., and can work effectively in the rated load for a long time.
