Features

• High reliability.
• Low voltage ripple.
• Wide input and output voltage. – from 60-90Vac
• High conversion efficiency.
• Low temperature rise.
• Built-in overvoltage protection (OVP).

Application fields

The EMSA200090-P5RP is suitable for the computer and its peripherals, as well as LED lighting equipment. It can also be used to power other DC devices, such as telecommunications devices, wireless devices, switches, routers, and other electronic devices.

Working principle

The EMSA200090-P5RP is a switched mode power supply (SMPS). SMPSs provide more power with less energy than traditional linear power supplies, improve efficiency, and are smaller and lighter than linear power supplies. The heart of the EMSA200090-P5RP is the switching power converter. It is composed of four main components: a bridge rectifier, an inductor, a capacitor, and a switch. The bridge rectifier is used to convert the AC input voltage to DC. The output voltage is then adjusted using an inductor and capacitor filter. Finally, a switch is used to control the flow of power and to regulate the output voltage.

Conclusion

The EMSA200090-P5RP is an AC/DC desktop, wall adapters and is suitable for the computer and its peripherals, as well as LED lighting equipment. It has low voltage ripple and high conversion efficiency. It is based on switched mode power supply which is more efficient than traditional linear power supplies and has a smaller and lighter size.
