AC DC Desktop, Wall Adapters are used for laptops, portable devices, and battery chargers. The CENB1020A0703F01 is a popular AC DC Desktop, Wall Adapter due to its high efficiency and low cost. This article will discuss the application field and working principle of the CENB1020A0703F01.

Application Field

The CENB1020A0703F01 is designed to accept input voltages between 100-240V AC. It is able to convert AC input power to DC output power with a maximum output current of 2A. It is a universal AC dc adapter, suitable for laptops, portable devices, and battery chargers. In addition, it has a UL/CE certification which is a sign of quality assurance.

The CENB1020A0703F01 also has high efficiency, ranging from 85% to 90%. This means that it is able to deliver power efficiently while reducing energy usage and heat dissipation. Furthermore, its compact size makes it ideal for devices with limited space. This AC-DC adapter is an excellent choice for applications requiring reliable, efficient and cost-effective power conversion.

Working Principle

The CENB1020A0703F01 works by using an internal oscillator to generate AC power, which is then converted to DC power. The ac mains voltage is rectified into DC and filtered by the bridge rectifier, and then regulated by a linear regulator. The output voltage of the regulator is monitored and adjusted using a feedback loop.

The oscillator runs at a frequency of approximately 50kHz, and generates up to 12V DC. This voltage is used to power the linear regulator, which is responsible for providing a stable output voltage. The output voltage of the linear regulator is monitored by a second-order error amplifier which is responsible for adjusting the current drawn from the ac mains. Once the power output is stable, the adapter is said to be in steady state operation.

The CENB1020A0703F01 also has some safety mechanisms in place. The adapter features an over temperature protection, over load protection, short circuit protection, and over voltage protection. These safety features ensure that the power supply remains safe and reliable.

Conclusion

The CENB1020A0703F01 is a popular AC DC Desktop, Wall Adapter due to its high efficiency and low cost. It is suitable for laptops, portable devices, and battery chargers, and is UL/CE certified for quality assurance. The adapter works by using an internal oscillator to generate AC power, which is then converted to DC power. The output voltage is then stabilized by a linear regulator, and the adapter is kept safe with its various safety features.
