High performance 90 W medical adapters ideal for hospital, mobile and in-home medical equipment


In response to the medical electrical device market’s demand for highly-reliable power supplies, Sunpower has released the Mean Well GSM90B series of high-performance 90 W desktop type medical adapters.

The entire Series has numerous international certifications that qualify it for the most demanding of applications, even those involving patient contact. With ultra-low leakage current levels under 100 µA, high efficiency of up to 91%, and a low no load power consumption of below 0.15 W, the range also achieves the high quality and high safety standards essential for medical power supplies. The built-in Active PFC function allows a power factor of better than 0.91.

Certification includes medical power supply regulation IEC60601 Third Edition, while the design follows 2xMOPP (Means of Patient Protection). The GSM90B Series also complies with the latest energy-saving regulations including ErP Directive Step 2 (Level V) issued by the European Union, the USA EISA 2007 (Energy Independence and Security Act of 2007) and others. Additionally, these efficiency levels allow cooling by free air convection. The operating temperature range is -30°C to +60°C. Power is supplied via a two-pole IEC320-C8 AC inlet, and a locking DC plug is optionally available.

These medical products operate from a full 80 -264 VAC input range and offer output voltages including 12 V, 15 V, 19 V, 24 V and 48 V to allow operation with many types of medical device. With no Frame Ground, they are Class ll units, fully enclosed within a UL 94V-0 flame retardant plastic case that also protects users from shock hazard. An LED indicator shows Power On status, and the GSM90B products have short circuit protection, overload protection, over voltage protection and over temperature protection. Safety in using the adaptors is comfortably assured by global safety certificates UL/CUL/TUV/CB/FCC/CE as well as household medical electrical device regulations EN60601-1-11 and ANSI/AAMI ES60601-1-11.

“These new GSM90B desktop medical adaptors are ideal for applications such as automated clinical chemistry analysers, analysis facilities, portable medical devices, medical computer monitors, home healthcare devices, and any medical equipment requiring low leakage current,” said Andy Wall, chief executive of Sunpower Technology.

“Additionally, they are the answer for electrical applications where low ‘no load’ power consumption is an essential requirement. Safety and suitability for these applications is assured by the level to which the range is certified, while its reliability is underwritten by its 100% full load burn-in test and our three-year warranty. ”
