The DDP400 U-chassis AC/DC power supplies are well suited for challenging system designs where low profile, low power dissipation is desired with minimal air movement. Its low profile is applicable for industry standard 1U equipment designs. Rated for 250W with free-air convection and 400W with forced air, this power supply includes an integral 12V fan output, eliminating the need for an additional fan supply. The power supply can be disabled with a logic signal and dissipates less than 0.5W in stand-by mode allowing for system level Energy Star compliance.
With typical efficiencies of 94% and efficiency load profiles that exceed 80 Plus Platinum requirements, the DDP400 is the most efficient power supply in its class.
