Description

LOP-400 is a 400W highly reliable green PCB type low profile power supply with a high power density (24.6W/in’) on the 5″ by 3″ footprint.
It accepts 80~264VAC input and offers various output voltages between 12V and 54V. The working efficiency is up to 95% and the extremely low no-load power consumption is down below 0.5W.
LOP-400 can be used for both Class I (with FG) and Class II (no FG) system design. LOP-400 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,
TEC/BS EN/EN60601-1.LOP-400 serves as a high-price-to-performance power supply solution for various industrial applications.
The extremely low leakage current is less than 500 mA. 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.
