SE-450 Series - 450W AC-DC Single Output Enclosed Power Supply



SE-450 Series, a 450W general purpose single output AC/DC enclosed switching power supply. Because the design has no PFC the cost of SC-450 can be maintained at a lower level making it an economical option for areas where the PFC function is not required, such as USA, China, Taiwan and South-Eastern Asia. The AC input range is selectable between 115/230VAC via the built-in switch. Using high frequency switching technology SE-450 possesses up to 88% high efficiency and 5.42W/in3 of high power density.
