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.
