Power Supply - AC Adapter

AC power adapters are external power supplies for portable computers such as laptops and tablets. As the name suggests, they convert AC power from the mains supply to a stable DC power that the computers require. Each Ac adapter has an output power rating depending on the device it is intended for. An external power supply has made it possible to design slimmer and more portable PCs.

Highly Efficient AC Adapters

When buying a new AC adapter, you need to consider its efficiency. Just as a reminder, this is the ratio of output power and input power. An efficient AC adapter reduces power wastage and generates less heat, a characteristic of almost all AC adapters. They depend 100% on the natural flow of air for cooling because of the less heat generated.

Ultimate Protection from Power Surges

Voltage spikes are rare, but when they occur, they can cause damages. AC power adapter is designed with protection features for over-voltage, over-current, short circuit, and over-temperature. Under no circumstance will your system be affected when there is a power problem on the mains. The over-temperature protection prevents the damage of the adapter itself, which should automatically recover when the condition is removed. Some adapters may require the disconnection of input power to the adapter.

Excellent Power Output

The AC power adapters here are all switch-mode power supplies. They can deliver more power than linear regulated power supplies for a given size and cost. It will not cost you as much as it would if you choose the linear regulated power supplies. SMPS are also known for high efficiency and reliability.

Buying the Right AC Adapter

First, define the intended use for your AC power adapter because every power supply is designed for a specific computer model or brand. For example, 609947-001 HP 90 Watt power supply is for HP ProBook computers, and 332-1829 Dell 130 Watt Ac power adapter is for Precision Mobile Workstation. As you can notice, different ac adapters have varying output power and voltage rating. Using the wrong adapter can destroy your computer! If concerned about the harmonics, then you can choose an external power supply with power factor correction.

Shopping for these external power supplies can be a daunting task because of the many variants on the market.
