MORNSUN 450-550W Medical AC DC Converter LOF450.jpg

Catering to the requirement for higher power AC/DC converter in Medical applications, MORNSUN launched the newly 450W and 550W LOF series products to provide customers more options this April.

Maintaining the high power density advantage of LOF series, LOF450 series has the dimension of 127mm × 76.2mm × 38.5mm (1.2W/cm³), and LOF550 series is 127mm × 76.2mm × 40.5mm (1.4W/cm³). These medical power supplies meet the reinforced insulation 2xMOPP, have active PFC function, and are designed to comply with medical electrical equipment standards (IEC/EN/ES60601-1 latest version), information equipment standards (IEC/EN/UL62368) and home appliance standards (IEC/EN60335, IEC/EN61558), making the products safe and reliable in applications.


It is suitable for BF medical devices and non-patient contact medical devices as its low leakage current, and also for industrial applications.
