When designing a mains power supply for a small load DC circuit, there are plenty of considerations. Small size, efficiency, and cost of materials all spring to mind. Potential lethality seems like it ...

This is the second in a two-part series looking at safety when experimenting with mains-voltage electronic equipment, including the voltages you might find derived from a mains supply but not ...

This month the cost and research departments of Mott Green & Wall and Davis Langdon & Everest examine the processes and options for the mains power supply connection from an electricity company's ...

Powerbox is aiming at data centres that use electronics flooded in liquid for cooling – so called ‘immerged applications’ – with a mains-to-12Vdc power supply. Called OFI600A12, it is the result of ...

Luso is stocking ac-dc mains power supplies that can deliver 130% of their rated power for 10 seconds. TAD30-P, TAD65-P and TAD125 are nominally rated at 30, 65 and 125W respectively, and “can provide ...

The MPS-2 has a maximum capacity of 160 MVA with dual step-down 132/33KV transformers. The MPS-2 is fully automated (unmanned) and equipped with advanced protection, fire fighting and monitoring ...

Many systems require a power multiplexer to select between two different power sources. For example, a PCI-based board needs to be able to select between the main power-supply rail and the auxiliary ...
