AC DC Desktop, Wall Adapters 816AR4201 application field and working principle The 816AR4201 is an AC/DC wall adapter manufactured by Global Power Technologies Group (GPT). It is a safe and reliable universal 100 to 240 V AC input. This adapter is designed to be used in a wide range of applications such as notebook computers, media players, and LCD monitors.The 816AR4201 has an integrated heatsink which dissipates heat generated during operation and prevents device from overheating. The device also features over temperature protection allowing the device to safely operate in harsh thermal ranges.The 816AR4201 also comes equipped with protection features such as short circuit, overload, over voltage, and over temperature. It also has a built in active PFC (power factor correction) to reduce EMI emissions and increase efficiency. This device also has an automatic Brownout/Voltage Detection System, which ensures the safety of your device by preventing voltage fluctuations.When it comes to performance, the 816AR4201 is equipped with a wide range of output capabilities ranging from 2.25A to 8A, and a power output up to 960W. This device also has an extended operating temperature range of -20° to + 90°C, and is highly reliable with MTBF of up to 50 000 hours.The working principle of 816AR4201 involves the use of a single-phase full bridge rectifier, which converts alternating current into direct current. The rectifier is composed of four main components, a diode, a transformer, a capacitor, and a transistor.The incoming AC voltage passes through the diode which allows current to flow in one direction only, and the transformer converts the AC voltage to DC voltage. The capacitor is then used to store energy while the transistor is used to switch the DC voltage depending on the output current required by the device.At the output end of the 816AR4201, a switching regulator is used to control the output voltage. This regulator uses a comparison between the output voltage and a reference voltage to adjust the output voltage accordingly.Overall, the 816AR4201 is a reliable and efficient AC/DC wall adapter that is suitable for a range of applications. It is designed for high efficiency, safety, and thermal performance. With a wide output current range and power output up to 960W, the 816AR4201 is ideal for powering a variety of electronics.
