MEA1 Series 1kVDC Isolated 1W Dual Output DC-DC Converters 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 MEA1 series of DC-DC converters are all 100% production tested at their stated isolation voltage. This is 1kVDC for 1 second. A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?” The MEA1 has been recognised by Underwriters Laboratory for functional insulation, both input and output should normally be maintained within SELV limits i.e. less than 42.4V peak, or 60VDC. The isolation test voltage represents a measure of immunity to transient voltages and the part should never be used as an element of a safety isolation system. The part could be expected to function correctly with several hundred volts offset applied continuously across the isolation barrier; but then the circuitry on both sides of the barrier must be regarded as operating at an unsafe voltage and further isolation/insulation systems must form a barrier between these circuits and any user-accessible circuitry according to safety standard requirements. 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 materi- als, construction and environment. The MEA1 series has toroidal isolation transformers, with no additional insulation between primary and secondary windings of enamelled wire. While parts can be expected to withstand several times the stated test voltage, the isolation capability does depend on the wire insulation. Any material, including this enamel (typically polyurethane) is susceptible to eventual chemical degradation when subject to very high applied voltages thus implying that the number of tests should be strictly limited. 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. This consideration equally applies to agency recognised parts rated for better than functional isolation where the wire enamel insulation is always supplemented by a further insulation system of physical spacing or barriers. SAFETY APPROVAL The MEA1 series has been recognised by Underwriters Laboratory (UL) to UL 60950 for functional insulation 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. The MEA1 Series of converters are not internally fused so to meet the requirements of UL 60950 an anti-surge input line fuse should always be used with ratings as defined below. MEA1D05xxxC: 1A MEA1D12xxxC: 0.375A MEA1D15xxxC: 0.375A MEA1D24xxxC: 0.2A MEA1D48xxSC: 0.1A All fuses should be UL approved and rated to at least the maximum allowable DC input voltage.

MEA1 Series 1kVDC Isolated 1W Dual Output DC-DC Converters 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%. Capacitive loading and start up Typical start up times for this series, with a typical input voltage rise time of 2.2μs and output capacitance of 10μF, are shown in the table below. The product series will start into a capacitance of 47μF with an increased start time, however, the maximum recommended output capacitance is 10μF.

MEA1 Series 1kVDC Isolated 1W Dual Output DC-DC Converters APPLICATION NOTES (continued) Output Ripple Reduction By using the values of inductance and capacitance stated, the output ripple at the rated load is lowered to 5mV p-p max. Component selection Capacitor: It is required that the ESR (Equivalent Series Resistance) should be as low as possible, ceramic types are recommended. The voltage rating should be at least twice (except for 15V output), the rated output voltage of the DC-DC converter. Inductor: The rated current of the inductor should not be less than that of the output of the DC-DC converter. At the rated current, the DC resistance of the inductor should be such that the voltage drop across the inductor is <2% of the rated voltage of the DC-DC converter. The SRF (Self Resonant Frequency) should be >20MHz. +VOUT L DC C Load Power OV Source DC C Load -VOUT L Inductor Capacitor L, μH SMD Through Hole C, μF MEA1D0505xC 10 82103C 11R103C 4.7 MEA1D0509xC 22 82223C 11R223C 2.2 MEA1D0512xC 47 82473C 11R473C 1 MEA1D0515xC 47 82473C 11R473C 1 MEA1D1205xC 10 82103C 11R103C 4.7 MEA1D1209xC 22 82223C 11R223C 2.2 MEA1D1212xC 47 82473C 11R473C 1 MEA1D1215xC 47 82473C 11R473C 1 MEA1D1505xC 10 82103C 11R103C 4.7 MEA1D1509xC 22 82223C 11R223C 2.2 MEA1D1512xC 47 82473C 11R473C 1 MEA1D1515xC 47 82473C 11R473C 1 MEA1D2405xC 10 82103C 11R103C 4.7 MEA1D2409xC 22 82223C 11R223C 2.2 MEA1D2412xC 47 82473C 11R473C 1 MEA1D2415xC 47 82473C 11R473C 1 MEA1D4805xC 10 82103C 11R103C 4.7 MEA1D4809xC 22 82223C 11R223C 2.2 MEA1D4812xC 47 82473C 11R473C 1 MEA1D4815xC 47 82473C 11R473C 1 www.murata-ps.com/support KDC_MEA1.C10 Page 5 of 9
