Working Principle

PSAA20R-120-R-C2 is an AC-DC switching adapter. The incoming AC power is first converted into DC power with the help of a rectifier circuit. Then, the DC voltage is further stabilized, regulated, and transformed into the desired voltage output with a switching converter. The output of the switching converter is then passed through an isolated DC-DC transformer to generate the desired output voltage.The switching converter also provides protection against dips and surges in the input voltage. When the current drawn exceeds the safety threshold, the switch will shut off the output power, keeping the device safe.The power adapter also features an LED indicator light to let the user know when the power is on. The LED will blink when the power is off to indicate a short circuit or depower.PSAA20R-120-R-C2 is a reliable and efficient power adapter for a wide range of electronic products, offering the utmost safety and convenience.
