AC DC desktop, wall adapters are commonly used in powering a variety of electric and electronic devices, ranging from cell phones to computers. The VEL05US120-US-JA is a universal 100 to 240V AC-DC adapter which can deliver a total output of 12V or 5V DC at up to 2A. It is extremely compact, measuring only 60x60x30mm, and it features protection against overcurrent, overheating, overvoltage, and short circuit.

This particular adapter is ideal for powering a variety of devices, most notably those that require a 5/12 V power supply. It has a wide range of applications in industries such as consumer electronics, medical equipment, telecom, audio/video, automotive, security, and computer networks. Moreover, the low noise, high efficiency, and universal AC input voltage range make it an ideal choice for a wide variety of applications, especially those that require a reliable and low-cost power supply.

The working principle of AC DC desktop and wall adapters is grounded in the conversion of energy from AC to DC. This conversion is done using either a linear or a switch-mode powersupply. In a linear power supply, the AC power is rectified and filtered, and then passed through a series of linear regulators that reduce the voltage to the required level. On the other hand, in a switch-mode power supply, the AC power is passed through a series of switches, which rapidly switch on and off and produce a pulsed DC voltage.

Once the AC power has been converted into DC, the DC power can be used to power a variety of devices. In the case of the VEL05US120-US-JA, the output is 5V/12V DC at up to 2A, and the voltage can be adjusted using the included trim pot. Furthermore, the adapter has an inrush current limiter, which ensures that the device being powered does not spike as it is turned on, and an over-voltage protection circuit that ensures the output voltage does not exceed the safe level.

Overall, the VEL05US120-US-JA is a compact and reliable AC DC desktop and wall adapter ideal for powering multiple devices simultaneously. Its wide range of features and applications, including its inrush current limiter, make it an ideal choice for those looking for a low-cost and reliable power supply solution.
