AC/DC Power Adapter

When designing your Products, have you ever encountered space constraints regarding the internal power supply section?

AC/DC Power Adapter are electronic components that contribute to the downsizing and weight reduction of your equipment by relocating the power supply section outside the device. In recent years, devices that previously used AC-AC power supplies have increasingly adopted DC output power supplies due to various reasons.

Familiar examples include the following devices:

Electric fans once commonly used AC motors, but DC motor fans designed for quieter operation have become mainstream.
Due to their light weight and ease of use, cordless vacuum cleaners and robot vacuum cleaners that use batteries have increased, and more of these devices are charged via AC/DC Power Adapter.
LCD televisions and monitors up to around 32 inches in size often use AC/DC Power Adapter.

As described above, by externalizing the power supply and adopting AC/DC Power Adapter, it is possible to achieve downsizing and weight reduction of equipment.

The Key Is "Safety and Reliability"

In the Japanese market, AC/DC Power Adapter are components subject to the PSE safety standard. This is a mandatory legal requirement to ensure the safety and reliability of Products. In overseas markets as well, they are regulated under the framework of EPS (External Power Supply). Different countries and regions have different regulations, and compliance with each applicable regulation is required.
