For lithium battery chargingAC/DC Power Adapter
There is a growing trend in customer requests and intended uses for AC adapters toward charging applications. For example, various Products, such as cordless cleaners, are being distributed in the market with charging functions as they become cordless. In addition, due to the charging functions of these Products, there has been an increasing demand to shift the supply method of conventional AC adapters from constant voltage (CV) to constant current and constant voltage (CC-CV). In response, UNIFIVE is now capable of providing design support for compliance with IEC60335-1 and 60335-2-29 for the following Products as well as other requested Products.
Applications
Charging devices with built-in lithium batteries (cordless vacuum cleaners, electric bicycles, electric scooters), etc.
