    A DC power supply is a device that maintains a stable voltage and current in the circuit, such as dry batteries, accumulators, DC generators, etc. The DC power supply has two electrodes, positive and negative. The potential of the positive electrode is high, and the potential of the negative electrode is low. When the two electrodes are connected to the circuit, a constant potential difference can be maintained between the two ends of the circuit, thus forming a circuit from the positive electrode to the negative electrode in the external circuit. A DC power supply is an energy conversion device that converts other forms of energy into electrical energy supply circuits to maintain a steady flow of current.

    Switching Power Supply

    15V DC 3A 100W switching power supplySwitching power supply, short for SMPS, is a high-frequency electric energy conversion device, which is a kind of power supply. Its function is to convert a level of voltage into the voltage or current required by the user through different forms of architecture. The input of the switching power supply is mostly AC power (such as commercial power) or DC power, and the output is mostly equipment that requires DC power, such as personal computers, and the switching power supply converts the voltage and current between the two. The switching power supplies on ATO.com can convert universal AC input to 5V/15V/12V/24V/48V DC output with short circuit, overload and overvoltage protection, complying with safety & EMC standards.  High quality 50W ~ 400W SMPS power supply is an ideal choice for switching on & off LED light strips, computers, printers and other power tools, office devices, household appliances or industrial equipment.
