VEH20US18 Application field and Working Principle

VHE20US18 is a power adapter belonging to the AC DC Desktop, Wall Adapters category. It is suitable for powering medium and low power electronic devices. This adapter runs on the United States\' 110V standard line voltage and provides 2A@18V DC output.

Application Field

VHE20US18 is mainly used as a power adapter for powering medium and low power electronic devices. These include smartphones, digital cameras, portable video players, portable game consoles, etc. This power adapter is suitable for indoor use only.

Working Principle

The VHE20US18 power adapter works on the principle of switching on/off cyclically at a high frequency. It converts the 110V AC voltage into 18V DC voltage through a high frequency conversion process. The current is then regulated via a series of transistors and other components to provide a stable DC voltage at the output.

The power adapter contains a high frequency transformer to convert the AC voltage into a high frequency AC voltage. This AC voltage is then converted into DC voltage via rectification. It is then further regulated using the transistors to provide a stable output voltage.

Safety Features

The VHE20US18 adapter is designed to protect devices from overvoltage, over current and short circuit. It also features a reliable thermal protection system. This system prevents the power adapter from overheating and protects connected devices from damage.

Conclusion

The VHE20US18 is a reliable power adapter belonging to the AC DC Desktop, Wall Adapters category. It is suitable for powering medium and low power electronic devices and provides reliable protection against overvoltage, over current and short circuit. It is a safe and reliable power adapter for indoor use.
