FXA 350 Series

The new 350W series, designed for both industrial (FXA 350) and medical applications (MSMP250), delivers an industry-leading converter efficiency of up to 88%. The power supply features a 5V standby output current and an adjustable fan output current. Both the FXA 350 and MSM P250 series features 350W of continuous output power with just 5 CFM of forced air. This high reliability series also offers active power factor correction of .98 to minimize input harmonic current distortion and ensure compliance with the international EN61000-3-2 standard. Designing in a FXA 350 ensures a highly efficient, highly reliable power solution.
