First off-the-shelf convection cooled CF-rated standard power supplies

Advanced Energy has released the NCF150 series of high-isolation, low-leakage current AC/DC power supplies that allow medical equipment designers to meet the CF requirements of the IEC 60601-1 medical safety standard using off-the-shelf products.

Type CF is the most stringent medical electrical safety classification and is crucial for medical products that may come in direct contact with the heart, including dialysis machines, cardiac-related systems, and electrosurgery platforms. With the launch of its series of CF-rated AC/DC power supplies, the company now provides standard, compact products that combine the performance and reliability demanded by complex medical systems with the high isolation voltage and low leakage current vital for CF certification.

“Until now, meeting the needs of the CF classification has required time-consuming and costly modification to traditional power supply,” said Shri Chandrasekharan, Advanced Energy’s senior vice president, Medical Power Products. “Now, with the launch of the NCF150 series, Advanced Energy is helping medical OEMs reduce the system level components required for isolation, minimise overall system size and cost, and speed time-to-market.”

The company’s SL NCF150 series delivers a maximum output power of up to 150W and offers voltages of 12V, 15V, 19V, 24V, and 48V. An optional 5V standby and 12V fan output are also available. All units in the SL NCF150 series have a patient leakage current below 10mA and feature EMI Class B, 2 MOPP isolation, and 5kV defibrillator pulse withstand capabilities.

The power supplies accept a universal input of 85VAC to 264VAC, operate with a full-load efficiency greater than 90%, and feature protection against overvoltage, overload, overtemperature, and short-circuit conditions as standard. This is the first release of the CF-rated family, which will be followed soon by higher-power models.
