Hermetic LED power supplies

Hermetic power supplies are power supplies that can work in external conditions. Characterized by varying degrees of water resistance from IP65 to IP67. Most MEAN WELL power supplies have IP67 water resistance. Only power supplies with voltage and current regulation (sybmol A e.g. HLG240H-12A) have a lower degree of protection IP65 due to the hidden potentiometer plugs.

Table of IP water protection levels:


IP60 without protection
IP61 protection against falling water drops
IP62 protection against falling water drops when the housing is tilted by any angle up to 15 ° from the vertical in each direction
IP63 protection against water spraying at any angle up to 60 ° from the vertical on each side
IP64 protection against splashing water from any direction
IP65 protection against water jet (12.5 l / min) poured onto the housing from either side
IP66 protection against a strong stream of water (100 l / min) poured onto the housing from either side
IP67 protection against the effects of brief immersion in water (30 min to a depth of 0.15 m above the top of the housing or 1 m above the bottom for housings lower than 0.85 m)
IP68 protection against the effects of continuous immersion in water (the housing is still immersed in water, in conditions agreed between the manufacturer and the user, but more stringent than according to number 7)
IP69 Protection against flooding with a powerful water jet under pressure (80-100 bar and temperature + 80 ° C) in accordance with DIN 40050
