Portable, safe design that factors in overheating resistance
We’re examining ways of reducing mounting space and making the AC adapter more compact.

AC Adapter Mounting Space

When you design your products, do you sometimes have problems with space in the internal power source?
An AC adapter is an electrical product that externalizes that space, making your product lighter and more portable. Nowadays, technology that once used AC-AC power has tended to favor DC output due to various circumstances.
 

Here are some familiar examples

・Electric fans once used mainly AC motors, but now quieter DC motors are the norm.
・Since they’re light and easy to use, battery-powered cordless vacuums have become more common, and the number that use AC adapters to charge is increasing.
・It is also common for LCD TVs up to 32 inches to use AC adapters.

As shown in these examples, when you change to an AC adapter, by moving the power source to the outside, you can decrease the size and weight.

Also, the most important feature is safety. AC adapters in the Japanese market are subject to the PSE safety regulations. In foreign markets as well, they are categorized as EPS (external power sources) and are subject to various regulations.

You can count on Unifive to take care of this kind of legal support too.

With our experience, ranging from foundational knowledge of the required standards to specialized areas, we can guide you through the steps to take.

If you’re struggling with downsizing your product that uses an AC adapter, have a look at our Unifive Products Lineup.
