These power supplies may be mounted for conduction or convection cooling, and are rated at 350 W in still air and 400 W with conduction cooling via the optional heat sink, or minimal forced air. The integral 12V fan output eliminates the need for an additional fan supply.

The sealed versions of the DDP400 AC/DC power supply family uniquely address harsh environment applications.
