AC/DC Switching Power Supply is designed for high efficiency and small size. They incorporate a switching regulator to convert electrical power efficiently. Switching DC power supplies regulate the output voltage through a process called pulse width modulation (PWM).
If your equipment is for international use, switching technology works almost anywhere in the world whereas a linear power supply must be manually adjusted to work with a foreign grid. Other examples of applications that prefer a switching Open Frame Power Supply are general purpose ones used in R&D, manufacturing, and testing, high power / high current applications, some communication systems, mobile stations, some network equipment, electroplating, anodizing, electroforming, electrophoresis, electrolysis, waste treatment, hydrogen generator, fuel cell applications, DC motors, aviation, and shipboard/boat applications.
What is an AC Adapter?
An AC Power Adapter is an external power supply that converts alternating current (AC) from a wall outlet to a direct current (DC) needed by an electronic device. Therefore, it is an AC/DC converter. When it supplies power to a battery-powered device, it is also accurate to describe it as a charger. Before picking the right AC adapter for your device, it is useful to know the reasons most portable electronics use external power adapters.
Check Electrical Ratings to Choose the Right AC Adapter for Your Device
Before trying to find a matching AC Desktop Power Adaptor for a device, check if the OEM (original equipment manufacturer) adapter is available. Device manufacturers sometimes offer replacement chargers/adapters for their products. Determining how to choose the right power adapter for a device becomes easy if this OEM accessory is available. Find the specific adapter for the device by searching for it using the model number printed on the adapter shipped with the device.
Remember the times when our smartphones required an entire night for a complete recharge? We are pretty sure there were also many instances here you left home with little charge on your phone and you might have regretted it. The introduction of fast Car Charger technology has changed it all. Just plug in your phone for a few minutes and your device has enough juice to keep running the entire day.
Since the most common lighting applications are in the range 1W-100W, LED Drivers are designed as switching mode circuits in order to reduce the power losses that generate heat inside the lamp.
