Overcoming reliability issues

Reliable power solutions for your application

Correct selection of a power converter for the application conditions seen by the end product is critical to long-term reliability. A power converter designed to minimize stresses on components during normal operation can still suffer from poor reliability if subject to excessive heat in the end installation.

Good thermal management is essential for maximizing reliability and XP Power offers a selection of converters with mechanical formats to match the thermal design required in different situations.

Frequently asked AC-DC questions

The conditions that you expect the AC-DC power supply to operate under can greatly affect the output power available. For instance, if the supply voltage is at the lower end of the specified operating range the output power may need to be de-rated. Likewise, if the temperature will be at the upper end of the specified range, then it may be required to de-rate the output power.


When selecting an AC-DC power supply the headline power rating may not tell the full story, the datasheet should always be consulted to ascertain the true specification, particularly when the operating conditions are at the upper or lower extremes. All XP Power products have comprehensive datasheets available, with de-rating information to assist in determining the most appropriate power supply for any given application.

High operating temperature in particular, can stress the electronic components that make up a power supply, reducing lifetime and therefore reducing reliability. Good layout design will ensure that heat generating components are adequately cooled and are kept away from temperature sensitive components. In operation, reliability will be maximised by providing adequate airflow and keeping the power supply within the specified operating temperature range.


AC-DC Power supplies from XP Power are designed for high efficiency thus minimizing thermal losses. Meticulous design using quality components aided by extensive testing and certification, results in excellent reliability.
