Isolated 1W Regulated Single Output AC/DC Converters KAC_BAC1C.C01 Page 3 of 14 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 BAC1 series of AC-DC converters are all 100% production tested at their stated isolation voltage. This is 4kVAC for 3 seconds. A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?” The BAC1 series has been recognized by Underwriters Laboratory to 277VAC for Reinforced Insulation. The BAC1 series has been certified by Demko to 277VAC 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 BAC1 series is pending recognition by Underwriters Laboratory (UL) to ANSI/AAMI ES60601-1 and provides 2 MOOP (Means Of Operator Protection) and 1 MOPP (means of patient protection) based upon a working voltage of 277VAC max., between Primary and Secondary. File number E202895 applies. EN62368-1 The BAC1 series has been certified by Demko (D) to EN62368 for reinforced insulation to a working voltage of 277VAC. Certificate number D-07177 applies. UL62368-1 The BAC1 series has been recognized by Underwriters Laboratory (UL) to UL62368 for reinforced insulation to a working voltage of 277VAC. File number E151252 applies. Creepage 8.3mm and clearance 6.6mm Working altitude OVC II 5000m FUSING As stated in the application notes, to meet datasheet specifications it is required that a 1W 10Ω fusible resistor is fitted.

Output Capacitance and start-up times The recommended specified caps on page 4 and 5 can already meet datasheet specification, there is no need to add extra caps. However, if customers connects to load capacitance, the below load capacitance are max (additional to recommended specified caps) to ensure start up at minimum AC input. Minimum Load The minimum load to meet full datasheet specification is 5% of the full rated load across the specified input voltage range. 24V output type - minimum input voltage requirements At -40C the part is guaranteed to start into 100% load with a minimum input voltage of 115Vac; once the product is operating, the product will continue to operate at lower input voltages with higher output loading. The product will start at -40C with 80% or lower load with an input voltage of 100VAC; once the product is operating, the product will continue to operate at lower input voltages with higher output loading. 3FUSE C2 D1 12 +Vout -Vout AC (L) AC (N) MOV FUSE 1W 10Ω fusible resistor MOV Component fitted for compliance with EN61000-4-5, Installation class 3, perf criteria A L1 330μH C1 6.8μF 400V C2 47μF 25mΩ low ESR polymer D1 SMBJ30A transient voltage suppressor - component fitted for overshoot protection Part No. Maximum Load Capacitance (per output) Start-up times (AC input) Start-up times (DC input) μF s s BAC1S05SC 220 0.5 5 BAC1S12SC 100 1 5 BAC1S24SC 100 1 5
