Wide input range
Rugged Industrial quality
Field proven design
Conduction/convection cooling
Full electronic protection

This rugged, industrial quality, DC/DC converter uses our field-proven PFC 150 dual conversion technology and delivers
up to 120W output power. The converter offers a wide DC-input voltage range of 90Vdc to 350Vdc. Cooling is via baseplate to a heat-sinking surface and by natural convection. The unit has a robust mechanical construction and all
components are conformal coated. Full electronic protection, low component count, large design headroom, and the
use of components with established reliability result in a high MTBF. The unit is manufactured at our plant under strict
quality control.
