| Transient Filtering Stage |
 As we mentioned on other articles and reviews, the first place we like to take a look when opening a power supply to have a hint about its quality is its filtering stage. The recommend components for this stage are two ferrite coils, two ceramic capacitors (Y capacitors, usually blue), one metalized polyester capacitor (X capacitor) and one MOV (Metal-Oxide Varistor). Very low-end power supplies use fewer components than that, usually removing the MOV and the first coil. This power supply has one X capacitor more than needed but it has only one ferrite coil instead of two.  click to enlarge Figure 6: Transient filtering stage.
A very interesting feature from this power supply is that its fuse is inside a fireproof rubber protection. So this protection will prevent the spark produced on the minute the fuse is blown from setting the power supply on fire. Now let’s have a more detailed discussion on the components used on Kingwin ABT-450MM. |
