AC/DC Power Adapters for Audio Equipment — Desktop & Wall-Mount

There are many requirements for the power supplies used in musical instrument products. Among them, the most important are measures against "acoustic noise" and "buzzing noise". Our company develops, manufactures, and sells various types of power supplies for musical instruments, ranging from those used in small speakers to large ones like digital pianos. We are capable of modifying various product lineups, including those compliant with the upcoming IEC62368 safety standard, according to your company’s requirements, or providing newly developed products in 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 based on IEC62368, IEC60065

* Power supplies for audio equipment may require specifications for specific noise from instruments, OCP value settings, etc., that cannot be supported by standard IEC60065 or IEC62368 compliant models.
