A rugged power supply unit is a form of power supply that is capable of withstanding a variety of environments, even those used in harsh and functionally demanding environments, with particularly challenging conditions and climates. These power supplies are designed and built for the sake of withstanding extreme or otherwise complicating weather and environmental conditions. These conditions include differences in altitude, temperature, vibrations and shock — perfect for suiting many different industries.
Rugged power supplies must have a wide input voltage range and excellent immunity to over-voltage and surges to function safely and reliably.
They also need to support a wide operating temperature range and be resistant to high humidity levels. When a power supply’s maximum operating temperature is surpassed, it can quickly lead to changes in performance, component failure, and reliability. Humidity can lead to condensation—and water is both conductive and corrosive, which is why a rugged environment power supply must be able to perform reliably and predictable even in the presence of elevated humidity levels.
