HWB-Series: Ultralow-Noise Switch Mode Power Supplies With SMZ Resonant Mode

The HWB series employs proprietary Soft-switched Multiresonant Zero-cross (SMZ) type resonant-mode circuits to achieve large noise reduction in the converter unit. Moreover, this is a switching power supply which has realized ultra-low noise (ripple voltage, conducted emission, and noise electric field strength) like a dropper power supply, employing a proprietary resonant mode hybrid IC and transformer.

Applications

  • Medical equipment
  • Measuring equipment, semiconductor manufacturing equipment, testing equipment, and control equipment
  • Equipment that has a dropper power supply installed
