    Switching Power Supplies

    Switching power supply, or switched-mode power supply (SMPS), is to utilize the electronic switching devices (such as transistor, MOFET, thyristor, etc.) for on and off constantly through the control circuit to make input voltage pulse modulation, so as to achieve DC/AC, DC/DC voltage conversion, output voltage adjustable and automatic voltage regulator. It is now widely applied to electronic devices by virtue of its outstanding performance in small size, light weight and high efficiency. The switching power supplies on ATO.com can convert universal AC input to DC with short circuit, overload and overvoltage protection, complying with safety & EMC standards.
