A highly efficient, fixed voltage, no load low power (0.2~0.75W) consumption enclosed power supply for a wide range of industrial applications. It is more compact and efficient than previous generation models. The 30mm low profile design allows it to be built into 1U rack enclosures, while the metallic mesh case enhances the heat dissipation. It is also capable of operating at altitudes up to 5000 metres. Not only will it satisfy every kind of industrial related application but can also be utilised for household appliances thus accounting for a broader coverage across diverse industries. .
