4"×2" 200W Open-frame Medical AC/DC Converter - LOF225-23BxxR2 Series

4'×2' 200W Open-frame Medical AC/DC Converter - LOF225-23BxxR2 Series.jpg

To meet the demand for power supply with the requirement of miniaturization and without an external fan, MORNSUN launched the LOF225-23BxxR2 series. These modules are optimized on the circuit layout and component heat dissipation design, feature a size of 4"×2" and an efficiency of 96%, suitable for applications requiring high power in a natural air-cooling environment.

LOF225-23BxxR2 series are suitable for BF-type medical applications (Medical system equipment accessible to patients). They feature active PFC function, 4000VAC high isolation voltage, meet medical standards (IEC/EN/ES60601), industrial standards (IEC/EN/UL62368, IEC/EN61558), and home appliance standards (IEC/EN60335), making them safer and more reliable in applications.
