The convection cooled rating is 120 W and the forced cooled rating is 180 W with only 10 CFM airflow. The efficiency curve is very flat with the active mode efficiency, taken at 25, 50, 75, & 100% load, exceeding 92%. Green mode operation means a no load power consumption of less than 0.5 W enabling end equipment to comply with the latest green legislation. The series carries 60950 and 60601 agency approvals up to altitudes of 5000 m and supports medical applications with requirements for 2 x means of patient protection.
