SMI18-18-K-P5 is a type of AC DC desktop, wall adapters. It is an AC DC power adapter that turns AC power from wall outlet to DC power for a laptop. It has wide application fields and working principles.
Application Fields
SMI18-18-K-P5 is suitable for computers, notebooks, laptops, LCD monitors, netbooks, etc. It is Light Weight with Low EMI and provides reliable AC inlet with universal coil. This product also delivers superior efficiency and can be used in medical, industry, marine, transportation and other industries. It has high-efficiency configurations that are approved for use in multiple countries.
Working Principle
SMI18-18-K-P5 AC DC desktop, wall adapter works on principle of AC to DC conversion. In order to convert AC power from wall outlets to DC power to be used in laptop, it features an internal switch mode power supply (SMPS) which step down the input voltage from 220V to 15V or other required DC power output. The required voltage is then passed through rectifier diode, capacitor and transformer to get the DC power. The power adapter provides regulated DC output at the required voltage, which helps protect the connected device from overvoltage and overcurrent.
This adapter has a power factor correction (PFC) circuit, which improves the energy efficiency of the adapter. It also has safety measures like over current protection (OCP) and short circuit protection (SCP) to protect the connected device from burnout due to wrong wiring or fault operation. The SMPS also has inbuilt temperature control that helps reduce the risk of overheating and boosts the overall performance of the adapter.
Conclusion
SMI18-18-K-P5 AC DC desktop, wall adapter is a popular choice for powering laptops. It is widely applicable and has superior efficiency. With its SMPS circuit, PFC circuit and several safety features, the power adapter is designed to provide regulated output without any risk of damage to the device. For these reasons, it is the go-to option for powering laptops and other mobile devices.
