Working Principle

FWC100048A-11B power supply device is with a full range of AC input and DC output, using a switch-mode power supply circuit, an oscillator, a rectifier, a filter, and an output voltage regulator. The circuit is composed of AC transfer to DC, and then to the AC-DC converter for conversion, and finally being filtered and rectified to output the DC voltage. The AC power first flows into the AC-DC converter and then to the full-wave rectifier, which converts the AC to DC. The energy stored in the capacitors is then used to make DC output, while the switching FET will switch the current from the power supply to the load.

The FWC100048A-11B includes an over temperature protection circuit with a current detector, which, when the current surpasses the rated current, will limit the current output from the power supply device.
