DPS120085UPS-P12P Application Field and Working Principle

AC DC Desktop and Wall Adapters

The DPS120085UPS-P12P is an AC/DC desktop and wall adapter designed for use with various kinds of electric and electronic equipment, such as computers, notebooks, LED, LCD monitors, TV, printer, fax machine, cameras, security systems, medical equipment, and so on. It is a reliable, energy-efficient, and miniature size power supply.

The DPS120085UPS-P12P provides more than 90 percent efficiency in any rated output power range, which means that it is better than most of the conventional linear adapters for energy saving. It also features a high component density, which reduces the printed board material need and total component cost by about 10–20 percent compared to traditional solutions.

The DPS120085UPS-P12P provides excellent electrical safety, with reinforced insulation and high EMI immunity. It comes with a secondary leakage circuit module, which controls the output current and voltage to ensure stability and safety during operation. It is compliant with FCC, CE, and RoHS standards, and has UL, CB and TUV certifications.

Working Principle

The DPS120085UPS-P12P uses a switch mode power supply (SMPS) topology. The power adapter input voltage is rectified and filtered into a constant DC voltage by a rectifier and a filter capacitor. It is then sent to a buck converter, where it is transformed into a regulated DC voltage. This regulated DC voltage is further filtered and regulated by a secondary circuit and output filter capacitors to smooth the voltage.

The secondary circuit of the DPS120085UPS-P12P also contains protection circuits that prevent the output current or voltage from exceeding the rated values. This ensures stable output protection and reliable operation. It also contains temperature protection circuits that shut the power off to protect the components from being damaged by high temperatures.

Conclusion

The DPS120085UPS-P12P is a reliable and safe AC/DC Desktop and Wall adapter that provides high efficiency and excellent electrical safety. It uses a switch mode power supply topology to transform a rectified and filtered input voltage into a regulated DC voltage, and additionally contains protection circuits, temperature protection, and secondary leakage prevention to ensure stable operation. It is certified compliant with FCC, CE, and RoHS standards, and is UL, CB and TUV certified, making it a reliable choice for many different kinds of electric and electronic equipment.
