After the launch of MSP-300 (300W) series, MEAN WELL further introduced the 200W AC/DC medical enclosed type power supply ~ MSP-200 series. Featuring high efficiency, low leakage current (≦450μA), extreme low no load power consumption (<0.5W) and 1U low profile (38mm), MSP-200 series complies with international medical safety regulations (MOOP level) and EMI Class B level, which can fulfill the high quality demands of medical applications and are good power solutions for medical measurement equipment and non-patient contact medical applications.

With up to date high frequency switching technology, MSP-200 possesses up to 89% high efficiency, so it can be cooled by free air convection at +40℃ambient temperature under full load condition, and even up to +70℃ by suitable derating. The standard functions include remote sensor, protections for short circuit, overload (constant current mode), over voltage, and over temperature. In addition, MSP-200 series units are equipped with 300VAC input surge immunity for 5 seconds, which can reduce the damage caused by an unstable AC mains. Meanwhile, these new models are equipped with built-in remote ON/OFF control and 5V/0.3A standby output to achieve the goal of “no load power consumption <0. 5W”, hence, they can be used in all kinds of “green mode” medical equipment or electric devices and fulfill the energy-saving requirements for end systems. The MSP-200 series complies with global certificates per UL/ CUL/CB/CE medical safety regulations and can guarantee your safety. Suitable applications include medical equipments requiring low leakage current, chemical and biological detection equipment, analysis facilities, and any systems that require low no load power consumption.
