detailed description
Description
The fanned versions of the DDP400 series include a fan off condition under light load operation (<50W). This optimizes audible noise for fan cooled products to the lowest levels possible and maximizes fan lifetime, an ideal combination for audio and process control systems where power supplies are sized for short duration peak demand cycles. With typical efficiencies of 94% and efficiency load profiles that exceed 80 Plus Platinum requirements, the DDP400 is one of the most efficient power supplies in its class.
