Datasheet - MDP400 Series

The MDP400 U-chassis medical grade power supplies are well suited for challenging system designs where low profile and low power dissipation are desired with minimal air movement. Its low profile is applicable for standard 1U medical equipment designs. Rated for 250 W with free-air convection and 400 W 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 0.5 W 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 MDP400 is the most efficient power supply in its class.
