  • Product Description
  • Product parameters

  • JBK1/2/3/4/5/6 series machine tool control transformer is suitable for the frequency 50Hz/60Hz AC circuit, the input voltage generally does not exceed 500V. As all kinds of machine tools, mechanical equipment in the general electrical control power supply, local lighting and power indicator. Adopting advanced technology and strict design for manufacturing, and selecting high-quality terminal, with excellent performance, reliable work, low energy consumption, small size, wiring safety, wide applicability and other characteristics, is an ideal control power supply.

     

    Product details advantage

    1. The windings are made of class H enameled copper/aluminum wire, which can withstand temperature up to 180 ° C, is well insulated and durable.

    2. New high-quality cold-rolled silicon steel core (oriented and non-oriented optional) , good heat dissipation, low core loss;

    3. The transformer whole H class insulation varnish vacuum impregnation, has the extremely high heat resistance, and anti-corrosion, the running noise is low, the insulation performance is good.

     

    This series of single-phase transformer is widely used in CNC machine tools and mechanical equipment, elevator control cabinet, working lighting and signal lamp power supply, can also be used as a small power supply.
