Description

LOP-300 is a 300W highly reliable green PCB type low profile power supply with a high power density (37.5W/in*) on the 4″ by 2″ footprint. It accepts 80~264VAC input and offers various output voltages between 12V and 54V. The working efficiency is up to 94% and the extremely low no load powerconsumption is down below 0.5W.
LOP-300 is able to be used for both Class I (with FG) and Class I(no FG) system design. LOP-300 is equipped with complete protection functions; It is complied with the international safety regulations such as IEC/BS EN/EN/UL62368-1,IEC/BS EN/EN60335-1,IEC/BS EN/EN61558-1/-2-16, IEC/BS EN/EN60601-1.LOP-300 serves as a high price-to-performance power supply solution for various industrial applications.The extremely low leakage current is less than 500 A.In addition, it conforms to the international medical regulations (2 MOPP) and EMC BS EN/EN55011, perfectly fitting all kinds of BF rated “patient contact” medical system equipment
