HK High Power Series

Inquiries
  • Applicable to high power output unit reactor (2KW~), which was difficult to achieve, donw by the big size core which is a combination of base blocks cores.
    Speeding up switching frequency become easier, maintaining highefficiency, when this choke coil is applied to high output inverter
  • Magnetic circuit can be smaller both involume and weight by 10% maximum, which became possible with U-shape base block, in comparison with combinations of only rectangular blocks.(comparison among our products)
