Compact 1 Watt DC-DC converter complies with UL60601-1 for medical safety

The converter is certified to a continuous working voltage of 200 Vrms when operating in a maximum ambient temperature of + 85 degrees C. Input to output isolation is rated at 5,200 VDC for 1 second. The series also complies with the 3rd edition of medical safety standard UL60601-1 and provides the following MOOP (means of operator protection): 2 MOOP based upon a working voltage of 200 Vrms max. and 280Vpkmax., between primary and secondary and 1 MOOP based upon a working voltage of 200 Vrms max., between primary and its enclosure.

The series comprises 38 models with both single and dual output versions available. Single output models provide 3.3, 5, 9, 12, or 15 Vout. Dual versions provide both positive and negative outputs; 5, 12, 15, or 24 Vin is accommodated across the whole range and single output models also have a 3.3 Vin option.

Typical energy efficiencies are in the range of 70 to 78%.

The MEJ1 series is designed for low power applications that require a high degree of isolation such as an agency-approved safety barrier for medical equipment, IGBT drivers, and control systems.

The converters are pin compatible with previously released models from Murata Power Solutions including the MEV, NMV, NMK, MEJ2, and NMJ series.
