Points to consider when buying a power supply

Protection types – It is important to choose a power supply that is protected against either short circuit, overload, over temperature or over voltage. Some power supplies also offer a hiccup mode which will allow the PSU to resume operation once the fault is cleared.
Fixed or adjustable output voltage or current – In test systems it is often convenient to have adjustable DC voltage however in other applications a fixed DC supply may be essential.
Cabling and wiring – The input/output lines to and from the power supply should be as short as possible with a large cross sectional area to help minimise noise and heat.
Efficiency – Choose a power supply that has a high efficiency to minimise the amount of power dissipation, especially if the system relies on convection cooling.
Input voltage range – If thel power supply you are buying is to be used in Europe and North America as well as the UK then a universal AC input range of 80 V ac to 264 V ac is required.
Standards – If the power supply is to be used in the USA for controlling electric motors then it will need to comply with Standard UL508, the safety standard for industrial control equipment.
