AC-DC POWER SUPPLIES 

## MCE03 Series 

## 3W 

The MCE03 series of PCB mount single output AC-DC medical power supplies delivers a power output of 3W and offers single output voltages ranging from 3.3V to 48VDC. The MCE03 series, which is available in open-frame and encapsulated mechanical formats, is specifically designed for medical applications with 2 x MOPP isolation and is approved for Class II applications. 

With world-wide medical safety approvals, class B compliance for conducted and radiated emissions, high efficiency, high reliability, 4kVAC isolation, the MCE series benefits system designers with easy integration into a wide range of BF rated medical applications including imaging, patient treatment, surgical equipment and home healthcare applications.
