Is your LED Power Supply Safe?
We first warned about this scenario 10 years ago, yet we are still seeing a worrying trend. Namely, customers requesting quotes for industrial enclosed power supplies to use as indoor LED drivers.
This can be dangerous.
Enclosed power supplies are designed to be used inside another piece of equipment or machinery, where they cannot be touched by an unqualified person. They have exposed AC terminals. Touching these could result in electrocution! The only time these power supplies can ever be used to power LED lighting is if they are used as a component inside a piece of finished equipment . Thay cannot be connected inline between an AC mains outlet and an LED luminaire.
If you need an indoor LED power supply, please use one of the dedicated indoor LED drivers we list on this website with an Australian flex and plug. Drivers without plugs should only be installed by a qualified electrician.
Technical question of the week: What is a Class 2 (Class II) Power Supply?
Power Supply Australia's response:
Believe it or not Class 2 and Class II are 2 completely different things.
Class 2 refers to a classification that appears in the National Electric Code (NEC) in the US. To prevent electrical cable overheating due to excessive currents and electric shock, the classifications limits the power output of a 24VDC AC-DC power supply to 100 watts.
This is why some DIN rail power supplies rated at 91W rather than 100W. This is because if the power supply is overloaded, any tolerance in the over current protection has to be accounted for.
Class II indicates that a power supply is double insulated and doesn’t need an earth pin. Some LED drivers and Power Adapters listed on this website are Class II power supplies and show this symbol on the product label.
