The MDS-200A series of internal open frame power supplies come with universal AC input range from 90Vac to 264Vac. Other features include low leakage, Type BF Patient Access Leakage Currents, and electric shock protection compliance with 2 x MOPP requirements. The MDS series is certified for EMC standards according to EN 55011 for industrial, scientific and medical (ISM) radio-frequency equipment; and, EN 55022 for Industrial Technology Equipment (ITE) radiofrequency equipment. In addition, only recognized Japanese capacitors are used to ensure long product life.
The MDS-200A series comes with both medical and ITE safety approvals, including UL/CE/CQC (5000 meters), and CB certification. Designs are compliant with RoHS Directive 2011/65/EU for environmental protection.
