5.2kVDC Isolated 2W DC-DC Converters KDC_MEJ2_M01 Page 3 of 10 www.murata.com TECHNICAL NOTES ISOLATION VOLTAGE ‘Hi Pot Test’, ‘Flash Tested’, ‘Withstand Voltage’, ‘Proof Voltage’, ‘Dielectric Withstand Voltage’ & ‘Isolation Test Voltage’ are all terms that relate to the same thing, a test voltage, applied for a specified time, across a component designed to provide electrical isolation, to verify the integrity of that isolation. Murata Power Solutions MEJ2 series of DC-DC converters are all 100% production tested at their stated isolation voltage. This is 5.2kVDC for 1 second. The MEJ2 series is recognised by Underwriters Laboratory, please see safety approval section for more information. When the insulation in the MEJ2 series is not used as a safety barrier, i.e. provides functional isolation only, continuous or switched voltages across the barrier up to 2.4kV are sustainable. This is established by measuring the partial discharge Inception voltage in accordance with IEC 60270. Please contact Murata for further information. REPEATED HIGH-VOLTAGE ISOLATION TESTING It is well known that repeated high-voltage isolation testing of a barrier component can actually degrade isolation capability, to a lesser or greater degree depending on materials, construction and environment. We therefore strongly advise against repeated high voltage isolation testing, but if it is absolutely required, that the voltage be reduced by 20% from specified test voltage. SAFETY APPROVAL ANSI/AAMI ES60601-1 The MEJ2 series have recognised by Underwriters Laboratory (UL) to ANSI/AAMI ES60601-1 and provides 1 MOOP (Means Of Operator Protection) based upon a working voltage of 200 Vrms max and 280 Vpk max., between Primary and Secondary and between Primary and its Enclosure, in a maximum ambient temperature of 85°C and/or case temperature limit of 130°C (case temperature measured on the face opposite the pins). File Number E202895 applies. UL60950 The MEJ2 series have been recognised by Underwriters Laboratory (UL) to UL60950 for basic/supplementary insulation to a working voltage of 200Vrms in a maximum ambient temperature of 85°C and/or case temperature limit of 130°C (case temperature measured on the face opposite the pins). File number E151252 applies. Creepage and clearance 2mm Working altitude 4000m FUSING The MEJ2 Series of converters are not internally fused so to meet the requirements of UL an anti-surge input line fuse should always be used with ratings as defined below. MEJ2x03xxxC: 2A MEJ2x05xxxC: 2A MEJ2x12xxxC: 750mA MEJ2x15xxxC: 750mA All fuses should be UL recognised and rated to at least the maximum allowable DC input voltage.

5.2kVDC Isolated 2W DC-DC Converters KDC_MEJ2_M01 Page 5 of 10 www.murata.com APPLICATION NOTES Minimum load The minimum load to meet datasheet specification is 10% of the full rated load across the specified input voltage range. Lower than 10% minimum loading will result in an increase in output voltage, which may rise to typically double the specified output voltage if the output load falls to less than 5%. Gate Drive Applications Advisory Note For general guidence for product usage in gate drive applications please refer to “gate drive application notes”.
