The EMSA050300-Z12P is a power supply solution intended for applications in AC/DC desktop, wall adapters. This technology enables high output power and excellent performance for commercial and consumer electronic products. It is designed to be integrated into wall outlets with UL,FCC and PSE certifications.

The EMSA050300-Z12P is a high-performance step down switching power supply that can provide up to 300W of regulated power output. It has a very wide input voltage range of 90~265Vac and can operate from a variety of universal AC mains. It features a universal input voltage range that allows it to operate from both single-phase and three-phase mains without requiring additional voltage transformers. It also features very low power factor correction, making it ideal for applications where high efficiency is a priority.

The EMSA050300-Z12P is also designed for high efficiency with a full-load efficiency of up to 91%, and a no-load power consumption of just 0.35W. It also provides high noise immunity, with an EMC assured level of 3kV signal and Surge rejection.

As with all AC/DC desktop, wall adapters, the EMSA050300-Z12P features an internal power supply that is integrated into the enclosure. The power supply is regulated to provide the stable output voltages and currents necessary for steady operation of the electrical equipment it is connected to. It is derived from the AC mains supply from the wall socket and is converted via the switching power supply technology.

The working principle of the EMSA050300-Z12P is based on a chopper circuit. This circuit operates at a high frequency in order to reduce the size of the transformer, allowing the power supply to be integrated into a small enclosure, while still maintaining output voltage stability. The chopper circuit converts the AC mains voltages into DC voltage. After this step, the DC voltage is converted to an adjustable DC voltage via a buck converter. The step down buck converter then provides stable regulated output voltage and current.

In summary, the EMSA050300-Z12P is a power supply solution intended for applications in AC/DC desktop, wall adapters. It features a wide input voltage range, a high efficiency full-load efficiency of up to 91%, and a low power factor correction. The chopper circuit converts the AC mains voltages into DC voltage, and then the step down buck converter provides stable regulated output voltage and current. In addition, it is designed to be integrated into wall outlets with UL,FCC and PSE certifications.
