CF-rated medical power supplies speed customer's time-to-market

Advanced Energy Industries, Inc. has expanded its family of convection cooled CF-rated medical power supplies with the launch of NCF660.

The system-level CF rating is the most stringent medical device electrical safety classification and is targeted at equipment with direct cardiac or bloodstream contact. The family joins the company's NCF family of products, which is a unique set of standard off-the-shelf power products that include less than 10µA leakage current and the high levels of isolation needed for these critical medical devices.

"The nature of CF-rated medical systems, which come into direct contact with the heart, has relied upon custom-developed power supplies and a lengthy certification process. Advanced Energy introduces these pre-qualified supplies as a standard product, with the aim to simplify design of these critical medical systems while ensuring high levels of patient protection," said Emdrem Tan, executive vice president, System Power at Advanced Energy.

By implementing NCF660, which is standard certified to the requirement of the IEC 60601-1 medical safety standard, medical system engineers can reduce time to market and lower non-recurring engineering costs. Also, the product family includes built-in power surge protection and improved thermal and EMI shielding that simplifies system design and reduces system size, weight and BoM.

Applications include surgical generators, cardiac assist devices and monitors, RF ablation, PFA, and hemodialysis.

The 660 W supplies feature 5 kV defibrillator pulse protection and meet the highest possible (2 x MOPP) means of patient protection rating, which requires isolation to 4 kVAC and a creepage of at least 8 mm.
