Improved Product Performance Through Power Supply Low Noise Measures

We offer specifications that minimize ripple and spike noise generated inside our AC adapters and board-mounted switching power supplies. By selecting this low noise specification, conducted noise performance is improved, and enhanced sound quality can be expected when used in audio equipment and electronic musical instruments. In addition, this low noise solution provides superior characteristics compared to conventional non-countermeasure products, even for wireless devices such as communication equipment and transceivers that require strict noise evaluation, making it an optimal solution for customers experiencing noise-related issues.
Quick Response Through Customization of Existing Products
For our products, we accommodate requests by modifying existing standard series, such as through component changes. Therefore, there is no need to release a new product series or change product names. We provide flexible support to quickly realize customization according to customer requirements. In particular, for products of 100W or less, customization and modification services are available starting from a minimum order quantity (MOQ) of 200 units. For products over 100W, customization and modification services are available starting from an MOQ of 50 units. This enables us to meet individual customer requirements and provide product customization.
If you require an AC adapter or open-frame power supply, please let us know that you prefer a low noise design product. We strive to provide products tailored to your environment and needs, and we encourage you to consider our solutions. We are always committed to maximizing customer satisfaction.
