General Description
The MDS series of external power supply comes with universal AC input at 90Vac to 264Vac. Other features include low
earth leakage, risk management report available and the electric shock protection comply with 2 x MOPP. 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 Information Technology Equipment (ITE) radio-frequency equipment. In addition, only
recognized Japanese capacitors are used.
The MDS series come with both medical and ITE safety approvals including UL/CSA/CCC/CE and CB certification and
are fully compliant with RoHS Directive 2011/65/EU for environmental protection.
