[Power Supply Design Proposal Example] Development of a Power Supply Device that Enables Output After Input Voltage Cutoff

We have developed a power supply unit with a built-in rechargeable battery and backup functionality!

We received a request to design a commercial power supply used in large PCs to continue outputting for a certain period of time even if the input voltage is interrupted due to power outages or other issues. In response, we have developed a power supply unit with a backup function that incorporates a rechargeable battery, allowing it to output 5V20A for 10 minutes after the input voltage is cut off. 【Case Overview】 ■Challenge - Design a commercial power supply used in large PCs to continue outputting for a certain period of time even if the input voltage is interrupted due to power outages or other issues. ■Solution - Incorporate a rechargeable battery to continue outputting 5V20A for 10 minutes after the input voltage is cut off. - Develop a power supply unit with a backup function. *For more details, please refer to the related link page or feel free to contact us.
