SL Power – MB65S: 65W AC/DC Power Supply Meets 4th Edition Medical Device Collateral Standards for EMC

The MB65S is certified for use in medical equipment in all regions of the world: it is approved to AAMI ES/CSA C22.2/EN/IEC60601-1, third edition with a two-fold Means of Patient Protection (MOPP); it is also appropriate for type BF isolation applications. The design takes into consideration the pending international release of the new IEC 60601-1-2, 4th Edition EMC requirements.

The MB65S internal power supply has been specifically designed for the new generation of medical devices and laboratory equipment that demand a higher level of EMC, EMI and AC input performance. Feature-rich and highly efficient, the MB65S product family consists of eight models; all can easily fit into a compact 1U chassis and provide 65W of convection-cooled power at a single output.

The power supply monitors the input and output and the internal temperature, and generates alarms when thresholds are crossed.

The MB65S also complies with the stringent EMC rules for applications requiring Class B conducted and Class B radiated EMI performance. Models carry cUL, CAN/CSA and DEMKO approval markings. In addition, the MB65S is rated for 560,000 hours of calculated mean time before failure.

The MB65S power supply operates from -20°C to +70°C and starts up at -40°C. It consumes less than 0.5W when supplying no load, helping prolong battery life when in Idle or Quiescent mode. In addition, the models are fully self-protected against short circuit, over-load and over-temperature conditions.
