Working Principle

ETSA120330UDC-P6RP-SZ AC/DC Desktop Wall Adapter is an automatic switching type power supply designed to convert AC power to DC power. The supply consists of an AC/DC converter circuit, a transformer, and a rectifier circuit. The AC/DC converter uses an IGBT switch to convert the alternating current to direct current. The transformer steps up the voltage input, and then the rectifier circuit rectifies the voltage to a constant DC voltage. The output is regulated using a voltage regulation circuit and a feedback circuit.

The ETSA120330UDC-P6RP-SZ also includes an overload protection circuit to prevent current surges. The circuit design includes a power factor correction circuit which helps to reduces EMI, thus reducing the risk of interference with other electronic devices in close proximity. The PFC additionally improves the power efficiency and saves energy.

The adapter also complies with safety approval standards such as IEC 60950 and CE. The safety design includes an internal fuse, a temperature protection circuit, and surge protection to help ensure maximum safety for consumers. This product also includes a EMC standard approval to prevent any harmful radiation or electrical interference.
