Summary

COSEL Power Supply, Noise Filter 2025 Product Catalog

Generally, switch mode power supplies are designed to operate in controlled environments (e.g. inside theoffice). The products should have a special care because some operating conditions may cause a malfunction orfailure of the products, smoke or fire at the worst case.1. Environment where some measures need to be taken(1) Water/HumidityIf the products are operated in environments wherewater drops into the products or condensation occurs, itmay cause a malfunction or failure of the products,smoke or fire at the worst case. In this case, please considerto take a water proof measure.(2) DustWhen the products are operated in a dusty place,components failures such as a fan may occur and dustwith moisture may cause insulation breakdown. Be cautiousthat these may cause a malfunction or failure of theproducts, smoke or fire at the worst case. In this case,please consider to take a dust proof measure.SPLASH!Oh. No!DustPower supply withbuilt-in fanPower supplyCoughing(3) GasWhen the products are operated in environments where a fumigation process (measures against insects when exporting)by halogen compounds such as methyl bromide is implemented or corrosive gas occurs, it may damage components andcause a malfunction or failure of the products, smoke or fire at the worst case.Halogencompounds(Fumigationprocess)Power supplyChlorine gasHydrogen sulfideSulfurous acid gas2. MeasuresTo take measures below is suggested when units are used in the environment above.1. Using units in the environment where units get watered or humidity is very high.(1) Semi-standard C(coating)(2) Stronger type than semi-standard C(Minor changed unit)2. Using units in the environment where something conductive is dropped into a unit.(1) Install air filter to an exhaust part.(2) Semi-standard C(coating)(3) Stronger type than semi-standard C(Minor changed unit)1. Attaching tube and silicon rubber to high voltage part.2. Attaching isolation cover to high voltage part.3. Using units in the environment where some gas get into units.(1) Some corresive gas cause units to be failed. Please contact us.The above may not be perfect measures. Please contact us about details.3
