For audio equipmentAC/DC Power Adapter

There are many requirements for the power supplies used in musical instrument Products. Among them, the most important measures are those against "acoustic noise" and "buzz noise". We develop, manufacture, and sell various types of power supplies for musical instruments for our customers, ranging from small speakers to large instruments such as electronic pianos. We can modify a wide lineup of Products, including those compliant with the upcoming IEC62368 safety standard, to meet your requirements, or newly develop and deliver products within a short period of time.

Applications and Features

Digital pianos, synthesizers, keyboards, amplifiers, speakers, etc.

  • Electrical characteristics: Input voltage 90~264V / Output voltage 15V/3A, 15V/4A, etc.
  • Applicable safety standards: CB, CE, PSE, UL, etc. based on IEC62368 and IEC60065

* For power supplies for audio equipment, due to special noise specifications on the instrument side and OCP setting values,
there are cases where standard IEC60065/62368 compliant products cannot be used.
