In response to the high reliable power supply demands of the medical market, MEAN WELL introduced the GSM40 & GSM60 series ~ 40W & 60W AC-DC desktop type medical adaptor, featuring high efficiency and low power consumption. Both series comply with international medical safety regulations as per 2*MOPP level. Possessing extremely low leakage current (<100 μA), 91% of high efficiency, and low no load power consumption they can fulfill the high quality demands of medical applications and are good power solutions for “patient contact” medical applications. The entire series comply with the latest energy-saving regulations (level V), such as ErP step 2 of European Union and EISA 2007 (Energy Independence and Security Act of 2007) of USA…etc.

GSM40 & GSM60 series have similar PCB designS and the same enclosure dimension of 125x 50x 31.5mm. With 80~264VAC full range input and output voltage options of 5V to 48V, to fulfill the demands of various medical equipment types, they are Class I power with earth ground pin and enclosed by UL 94V-0 rated plastic case, which can effectively prevent users from electrical shock. Other standard functions include: LED indicator, protections for short circuit, overload, over voltage, and over temperature. GSM40/60 also have global safety certificates for UL, CUL, TUV, CB, FCC, and CE which greatly guarantee the safety and reliability for all different applications such as medical equipments requiring low leakage current, chemical and biological detection equipments, analysis facilities, and any electric systems have low “no load power consumption” requirement.
