Issue 7 2025

The NCM3 series power modules from Murata provide a 3 W power output, and are backed by safety certificates with reinforced insulation sufficient for use in mains-powered industrial, medical and energy equipment.

The NCM3 series from Murata are isolated 3 W dc-dc converter modules which are certified for use in medical equipment.

 

Operating from an input-voltage range of 9 V to 36 V, the NCM3 converters supply a regulated output voltage of 5 V, 12 V or 24 V.

 

The NCM3 modules offer 250 Vrms of reinforced insulation according to the UL62368-1 standard. The series has a pending certification for ANSI/AAMI ES60601-1 for two means of patient protection (MOPP), making it suitable for use in mains-powered equipment in both medical and other high-voltage applications.

 

The surface-mount package supports high-speed automated product placement.
