SMPS DC 60V 20A 1200W Switching Power Supply

Switching power supply are made to be compact and highly efficient. To effectively convert electrical power, they use a switching regulator. Switching DC power supply use a technique known as pulse width modulation (PWM) to control the output voltage. Depending on the output power requirements, a PWM enables the use of a variety of topologies, including buck, boost, forward converter, half-bridge rectifier, and flyback. Although the PWM technique produces some high-frequency noise, it makes it possible to construct switching power supplies with a tiny form factor and extremely high power efficiency. A switching power supply with a proper design can have excellent line and load regulation. To obtain the required output voltage, they can either step up or step down the input voltage. Due to the switching transistor's low power dissipation when functioning as a switch, a switch power supply is more efficient than linear regulators. Filtering, however, can reduce the noise that this switching may produce.
