CE marked and TUV tested for safety in medical instrumentation

Dowload printable application note (160Kb)

Medical instrument designers appreciate the reliability and certified safety of BEAR power converters. All BEAR power supplies are tested against medical equipment safety and EMC standards including UL, IEC, CAN/CSA and EN. They are RoHS compliant and safe for use in lead-free wave solder lines.

You’ll save hours of time knowing that all of your power circuitry is pre-tested and pre-approved. And you’ll have the confidence of long life and reliable operation from your power supply in use. 

Features of BEAR power supplies for medical instrumentation

• Low leakage currents, very quiet outputs, and low conducted and radiated noise for sensitive medical instruments
• Low turn-on inrush current for fewer nuisance fuse failures and less stress on the converter for longer power supply life 
• High reliability in critical life-saving instruments
• Compact size for smaller, more portable systems
• High efficiency – no need for a cooling fan – resulting in smaller, quieter systems
• Some feature remote on/off, allowing you to design a front panel power button without routing line voltages to the front of the equipment
• Operation over international voltage ranges
• Medical certification testing 

All BEAR Power Supplies undergo the following certification testing for medical instruments: 

• UL2601-1 Medical Electrical Equipment: General Requirements for Safety
• IEC 601-1/A2 Medical Electrical Equipment: General Requirements for Safety
• CAN/CSA-C22.2 (No.601.1-M90) Medical Electrical Equipment, Part 1: General Requirements for Safety and Collateral Standard: Safety Requirements for Medical Electrical Systems
• EN 60601-1-2 EMC Standard for Medical Devices including:
  o EN55011 Conducted and Radiated Emissions 
  o EN 61000-3-2 Harmonics 
  o EN 61000-3-3 Flicker 
  o EN 61000-4-2 Electrostatic Discharge 
  o EN 61000-4-3 Radiated Immunity
