A: Assuming the same power output the switching type will be lighter in weight and less bulky.
A switching power supply adapter from Dee Van Electronics.
EZ Bridge
auto-switching power supply
Normal power supplies are on all the time while switching type are on and off periodically which results in precise control and improved efficiency.
Answer for countries in Europe and other world areas running a 50 Hz supply service.AC power supply is 230 v supply used in our homes for switching on fans, bulbs etc. where as DC power supply is used for switching on our laptops, charging our mobiles phones, i pods etc.
A switching mode power supply works by converting electrical power efficiently by converting voltage and current characteristics. However, it minimizes wasted energy by constantly utilizing on and off states.
A power supply fan keeps the power supply cool. The semiconductor components get hot in a switching power supply, and this fan keeps things cool and helps prevent the power supply from damaging itself from excessive heat. As an example, when you play games, the video card requires a lot more current. That means the power supply has to work harder. The switching transistors in the power supply have to operate at a higher frequency and pass electricity through them a higher percentage of the time. That in turn causes them to get hot. The fan helps pull this heat away and protects these components.
A pulse width modulated signal would be very useful in a switching power supply. This is but one example. Note, however, that there are better examples than the 555 for use in a switching power supply.
It is a switching regulator.
I have one bout to post on ebay im not sure what its for but its ITE POWER SUPPLY MODEL U120650A63 WHATS IT FOR?
A 12V switching power supply is an electronic device that converts high-frequency alternating current (AC) to low voltage direct current (DC) that can be useful for powering electronic devices that require low voltage DC power, such as LED lights, home appliances, and computers.
