Designed to meet the unique power supply requirements of home healthcare equipment, SL Power Electronics announces its newest family of medical-grade external power supplies. The 60W ME60 series is also approved to IEC 60601-1-2 Fourth edition EMC requirements; AAMI ES/CSA C22.2/EN/IEC60601-1, third edition with 2xMOPP; and U.S. Department of Energy’s Level VI efficiency requirements.

These models are specifically designed for next-gen home healthcare medical devices such as surgical, patient monitoring equipment and therapeutic electro-medical devices that require a high level of EMC, EMI and AC input performance.

Cochise Mapa, Director of Global Product Management, SL Power Electronics, commented: “With the rapid advances of telemedicine and home healthcare devices, we’re pleased to offer medical power solutions that provide maximum performance as well as exceed stringent medical device requirements. Design engineers can trust that our solutions meet the highest of safety standards and performance reliability.”

The feature-rich power supplies use high-quality electrolytic capacitors, assuring the ME60 series of a seven-year plus product life. Low common mode noise, high levels of ESD (IEC61000-4-2, level 4 standard: 8kV/15kV) and surge protection (IEC61000-4-5, level 4 standard: 2kV/4kV) help to ensure the highest overall performance.

Demonstrating a MTBF greater than 250,000 hours, the ME series offers Class B EMI filtering with 3db margin. In addition, with many input connection types (IEC60320 C14, C8 or C18 grounded or ungrounded; ungrounded wall-plug) these models can be used anywhere around the world.

Housed in an impact resistant polycarbonate enclosure that adheres to the IP22 requirement for dust and water ingress protection, the desktop and wall plug models offer regulated output power with low ripple, no-load power consumption greater than 0.5W and short circuit and thermal protection. With an operating temperature range from 0 to 50°C, the units comply with worldwide safety and performance standards from UL, cUL, CE and RoHS. Interchangeable blade option and modified or custom designs are available as well as custom labelling.

The ME series complement SL Power’s comprehensive external power supply product offering with incremental power levels from 10 to 220W and various DC output connector options, providing maximum flexibility in form factor. Featuring an industry leading three-year warranty, pricing for the series starts at $22 for production quantities and are available now through SL Power’s worldwide distribution sales channels.
