Switching Power Supply
Power Supply Unit is the electronic circuit used to provide energy for active components in electronic equipment. Certainly every electronic device using the Power Supply Unit.
Each active component in electronic equipment, require a different voltage and current, such as 5V, 3.3V, 12V etc. In carrying out their duties, this unit works very hard and usually result in excessive heat. This could damage the Power Supply Unit when you can not handle it correctly.
Most of the damage of electronic equipment located on the power supply unit. Actually it is not difficult to fix, if you know the correct procedures. Those experienced electronic repairers know that having the right procedure to troubleshoot and repair power supplies is the key.
