Applied for a specified time, across a component designed to provide electrical isolation, to verify the integrity of that isolation. Professional Power Module D-XN(S)D 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 specific agency approvals, such as the D-XN(S)D 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-acssible 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 D-XN(S)D 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 specified test voltage. This consideration equally applies to agency recognized parts for better than functional isolation where the wire enamel insulation is always supplemented by a further insulation system of physical spacing or barriers. 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: Ceramic chip capacitors are recommended. It is required that the ESR(Equivalent Series Resistance)should be as low as possible.X7R 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 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. OUTPUT RIPPLE REDUCTION Ripple & Noise Characterisation Method Ripple and noise measurements are performed with the following test configuration. C1 1uF X7R multilayer ceramic capacitor, voltage rating to be a minimum of 3 times the output voltage of the DC/DC converter C2 10uF tantalum capacitor, voltage rating to be a minimum of 1.5 times the output voltage of the DC/DC converter with an ESR of less than 100mΩ at 100 KHz C3 100nF multilayer ceramic capacitor, general purpose R1 450Ω resistor, carbon film,±1% tolerance R2 50Ω BNC termination T1 3T of the caox cable through a ferrite toroid RLOAD Resistive load to the maximum power rating of the DC/DC converter. Connections should be made via twisted wires Measured values are multiplied by 10 to obtain the specified values.
