Murata Power Solutions BAC3 series of AC/DC converters are all 100% production tested at their stated isolation voltage. This is 4.7kVDC for 1 second. The BAC3 has been recognised by Underwriters Laboratory to 240Vrms for Reinforced Insulation. 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 BAC3 series is pending recognition by Underwriters Laboratory (UL) to ANSI/AAMI ES60601-1 and provides 1 MOPP (Means Of Patient Protection) and 2 MOOP (Means Of Operator Protection) based upon a working voltage of 240Vrms max., between Primary and Secondary. File number E202895 applies. EN62368-1 The BAC3 series has been certified by Demko (D) to EN62368 for reinforced insulation to a working voltage of 240Vrms. File number D-07177 applies. UL62368-1 The BAC3 series has been recognised by Underwriters Laboratory (UL) to UL62368 for reinforced insulation to a working voltage of 240Vrms. File number E151252 applies. Creepage and clearance 8.4mm Working altitude OVC II 5000m IEC61558-1 & IEC61558-2-16 The BAC3 series has been certified by TUV SUD to IEC61558-1 & IEC61558-2-16.
