product description

WBK (BK) series control transformers are based on the domestic BK series control transformers. After years of further absorbing the advantages of similar products at home and abroad, they are manufactured with advanced technology and rigorous design. First, foreign advanced methods are given priority to terminals, which have excellent performance. , Reliable work, low energy consumption, small size, safe wiring, wide applicability and other characteristics, is an ideal transformer power supply. The company's WBK transformer won the title of national patent product.

Scope of application

WBK (BK) series control transformers (hereinafter referred to as transformers) are suitable for AC circuits with a rated power supply voltage of 50~60Hz and a rated power supply voltage not exceeding 1000V, as control power supply for machine tools and mechanical equipment, working lighting and signal lamp power supply; also as a small power supply Power function.

Models and what they mean

Use environment and normal working conditions

★The altitude does not exceed 2000m;

★The maximum ambient temperature is +40℃, the highest monthly average temperature is not more than +30℃, and the annual average temperature is not more than +20℃;

★The relative humidity of the air is not more than 95%;

★The ambient air does not contain harmful gases or dust that corrode metals and damage insulation; during use, the transformer must not be eroded by water, rain and snow;

★The waveform of the power supply voltage is similar to a sine wave.

Precautions

★Before buying, first estimate the total capacity of the electrical appliances you use, and choose a transformer with a considerable capacity to ensure that the transformer will not be burned out during instant start.

★The transformer is designed and produced in strict accordance with the relevant national standards. When you use a transformer with multiple windings (multiple control voltages), the capacity of the transformer should be increased according to the voltage ratio, so as to avoid burning out the transformer.

★Before installation, you should carefully check whether the data listed on the nameplate meet your requirements.

★After the power is turned on, the core and coil of the transformer will heat up (but the temperature rise does not exceed 80℃), which is a normal phenomenon. If the temperature rise does not exceed 80 ℃, or even smoke, you should cut off the power switch and re-check the capacity of the electrical appliance you are using.

★ During transportation, avoid collision as much as possible, and do not get wet. When using, please pay attention to maintenance to protect the service life of the transformer.
