Why is it important to protect your power supply?

Additionally, safeguarding the interior of the power supply against intrusion by foreign objects, such as tools, screws, wires, and accidental user contact, is crucial. Particularly when power supplies are installed outdoors, attention to the International Protection (IP) code is vital for safe usage and to mitigate costly downtime.

How does a power supply protect the ground?

Power supplies fall into one of three protection classes, based on the need (or not) for a protective earth connection known as ‘earthing’. This works by providing a path for a faulty electrical current to flow to the ground, shielding users from shocks when equipment insulation fails.

What is an IP rating on a power supply or LED driver?

Some MEAN WELL power supplies and LED drivers have an Ingress Protection (IP) rating stated in their data sheet. If there is none mentioned then assume that the power supply is only suited to use in a clean indoor environment. The IP rating number indicates what level of ingress protection the power supply or LED driver has been tested to.

Do industrial power supplies have an IP20 rating?

Industrial power supplies housed within cabinets typically bear an IP20 rating, whereas those positioned outside protective environments necessitate higher ratings, such as IP54 or IP67. Learn about IP codes and their significance in selecting power supplies, ensuring protection against foreign objects and moisture ingress.

Why is it important to protect the interior of a power supply?

Environmental factors such as dust or moisture can hinder the proper functioning of electrical components within a power supply. Additionally, safeguarding the interior of the power supply against intrusion by foreign objects, such as tools, screws, wires, and accidental user contact, is crucial.

How does a power supply protection work?

Some power supply protections utilize functional grounding instead of protective earthing. This process uses a transformer and allows the electricity to reach the ground while preventing the faulty current from doing so.
