Understanding Power Supply Repair Safety
It is very important to know the power supply repair safety before you begin to dismantle the equipment. If you accidentally
caused a small amount of current to flows through your body, you may get a shock and even death! Always be alert when deals with power
supply. Understand how electricity and power supply work can help you to avoid from electrocuted. Always wears a rubber shoe and have an
isolation transformer in your technical department or working area. You may find out more information about isolation transformer by
searching on the internet.
If you want to check the hot section in a power supply, always use the one hand ‘rule’ so that it would not complete a path for
current to flows through your body just in case if you were to accidentally touched a live connection or cable. If you are tired and weak,
do not repair any electronic equipment or else you might end up causing more problems for the equipment by replacing a wrong component.
Take a break and come back to tackle the problem when you are fresh again.
Always use original part numbers for replacement when dealing with components in the critical section such as the fuse area. If
the fuse rating is 3 ampere, then you must replace it with the same value which is 3 ampere.
Sometimes a slightly higher ampere such as 3.15 ampere may be acceptable. Do not use a 10 or 15 ampere for replacements otherwise fire may
occurred due to over current because the fuse would not melt.
The main filter capacitor with a high capacitance and voltage must be installed in the correct location. The positive marking at
the capacitor must be insert to the hole where it printed (+) and a negative one to (-). A wrongly installed filter capacitor can cause the
filter capacitor to explode and may injure your face if you are near to it. In some severed case, the blown capacitor may burn up the power
supply as well.
Lastly, don’t because of this information, scared you away from repairing a power supply. Just make sure you understood the power
supply repair safety first and things will become easier. Understanding the safety procedure above can protect your life and you will have
lots of time to repair power supply. Let’s go after the culprit!
