AC DC Converters

HDBB105W-A+G is a type of AC/DC converters used by consumers worldwide for an array of purposes such as power supply, solar panel and AC mains monitoring. This family of AC/DC converters provides an efficient and reliable conversion from AC to DC, making it ideally suited for use with microcontrollers, digital storage devices, high-resolution audio equipment as well as many other electronic equipment.

Application Field

HDBB105W-A+G is mainly used in low voltage applications, with maximum direct current output of up to 8 Amps. Its wide input voltage range of 85-265VAC ensures compatibility with most AC mains sources, making this converter appropriate for applications in countries or regions where multiple AC mains voltages are available. It is suitable for applications such as solar panel and AC mains monitoring, office automation, factory automation, building automation, illumination and many other embedded systems.

Working Principle

The AC/DC converter works on the principle of Rectification. A bridge rectifier is used to convert the AC sine wave electric current into pulsating DC current. To reduce the ripple, an electrolytic capacitor is usually connected in parallel with the output of the bridge rectifier. This reduces the ripple proportionally to the equivalent series resistance of the capacitor in the circuit. A special voltage regulator (voltage reference) is used to reduce the output voltage to the desired level in order to stabilize the output voltage and maintain it at a consistent level.

The HDBB105W-A+G AC/DC converter is also protected against overvoltage, low voltage and overload. If the input voltage exceeds the set threshold, the converter will switch itself off automatically to protect the attached device from damage. Similarly, if the output voltage or current is too low or too high, the converter will shut down to protect itself from damage.

Conclusion

The HDBB105W-A+G AC/DC converter is a reliable high performance AC/DC converter. It is designed to meet the demands of a variety of applications. It offers high efficiency and excellent EMI performance, making it well-suited for a wide range of consumer and commercial electronic applications. This family of converters also provides protection against overvoltage, low voltage and overload and delivers consistent output voltage and current at all times.
