As the first fanless power supply to market, the revolutionary Excelsys CoolX®600 series is a convection-cooled, modular power supply platform offering comprehensive features and specifications. Boasting 93% efficiency, it delivers 600 W from a very compact 215.9 x 114.3 x 39.1 mm package. 

Two base models are available. The CX06S complies with the IEC60950 (second edition) for industrial applications and will comply with the upcoming IEC62368-1 standards. The CX06M carries the IEC60601-1 (third edition) and IEC60601-1-2 (fourth edition, EMC) certifications for medical applications. The CoolX600 can be populated with four CoolMods, providing up to eight isolated DC outputs that range from 1 to 58 V. Outputs can be parallel connected for higher currents and series connected for higher voltages (up to 232 VDC).
