Elpac Introduces 250W Open Frame Medical Power Supplies

Elpac Electronics, Inc. announced the release of its new MSMP250F series of 250W open frame power supplies for medical applications. The new RoHS compliant models – which provide high power density (5.8w/in3) – feature Zero Voltage Switching (ZVS), synchronous output rectifiers, wide range ac input with power factor correction, and fully regulated output for use in a wide variety of mobile or portable medical applications.

The MSMP250F series includes five new models, each providing 250W of dc power at single outputs of 12, 15, 24, 28, and 48V. Each model takes ac input from universal sources and provides fully regulated dc output. All medical agency and regulatory approvals have been completed, including UL2601-1, CE marking, and FCC Class B.

The new models meet 2008 CEC standards for efficiency and zero load power consumption. The series features an extended life of greater than seven years at maximum load. Additionally, the new 250W series provides up to 250W with convection cooling and up to 350W with forced air cooling while maintaining a very high voltage dip immunity.

"We are increasingly seeing medical applications that call for higher power density and higher efficiency without compromising reliability. The new 250W series addresses the needs of many medical OEMs," said Marshall Wright, Elpac Chief Operating Officer. "We also continue to see medical equipment OEMs preferring to choose medical grade power supplies from a company known for making product with industry-leading quality, available fast, backed by superior customer service."

The new models operate over an ambient temperature range of 0 to 50.° All models contain over voltage, over current, and short circuit protection.
