For further information, please visit www.murata-ps.com/rohs 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 specied time, across a component designed to provide electrical isolation, to verify the integrity of that isolation. Murata Power Solutions NMA 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 For a part holding no specic agency approvals, such as the NMA series, 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 materials, construction and environment. The NMA series has toroidal isolation transformers, with no additional insulation between primary and secondary windings of enameled 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 specied test voltage. This consideration equally applies to agency recognized 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. APPLICATION NOTES Minimum load The minimum load to meet datasheet specication is 10% of the full rated load across the specied input voltage range. Lower than 10% minimum loading will result in an increase in output voltage, which may rise to typically double the specied output voltage if the output load falls to less than 5%. www.murata-ps.com/support KDC NMAC2.G02 Page 2 of 4
