FSA 150 Series

The FSA 150 series is a compact, open frame switch mode power supply that offers an industry leading 9.8W/in³ power density and up to 94% converter efficiency. Suited for light industrial applications where space is at a premium, the FSA 150 is offered in the industry standard 3in x 5in open frame and can be used in 1U applications. The FSA 150 features 150 watts of continuous power under free air convection and raises to 180W with just 100 LFM of forced air. The FSA 150 comes with a wide set of safety approvals and is comprehensively protected against over-voltage, over-temperature, and short-circuit conditions. ICCNexergy FSA 150 Series
