420AS04100

The 420AS04100 is an AC/DC desktop wall adapter that can provide up to 85 watts of output power and has a wide range of power applications. The 420AS04100 is a universal AC input voltage that works with input voltages ranging from 100 to 264 VAC (47-63 Hz). It accepts up to two input plugs, allowing it to be used in both North American and International markets.

This adapter is designed with an integrated selector switch allowing users to select the required output voltage from 5V, 12V, 15V, 24V and 36V. The output current for this adapter ranges from 3.5A to 1.8A depending on the power rating and output voltage. The adapter has over-load, over temperature and short-circuit protection features to ensure safety.

The 420AS04100 is suitable for a variety of applications such as powering CCTV systems, lighting, PCs, mobile phones, automotive and medical equipment. It is also UL and CSA approved making it ideal for environments where safety is paramount.

The working principle of the 420AS04100 is fairly simple. Input voltage is first rectified to DC by a bridge rectifier. The filter capacitor then filters out the AC ripple, with the smoothed DC voltage then passed on to the voltage regulation stage. In this stage the appropriate output voltage is regulated by a switch-mode switching regulation principle, providing the final output voltage. AC ripple is then suppressed by the EMI filter, providing a perfectly clean, regulated DC output voltage.

Overall the 420AS04100 is a high-quality adapter that is perfect for providing reliable power for a variety of applications. It is safe and simple to use, with its switch-mode switching regulation principle providing a clean and efficient final output.
