The isolation is basic insulation. For applications requiring basic insulation,care must be taken to maintain minimum creepage and clearance distances when routing tracesnear the power module.As part of the production process, the power modules are hi-pot tested from primary andsecondary at a test voltage of 1500Vdc.To preserve maximum flexibility, the power modules are not internally fused. An external inputline normal blow fuse with a maximum value of 15A is required by safety agencies. A lower valuefuse can be selected based upon the maximum dc input current and maximum inrush energy ofthe power module.When the supply to the DC-DC converter is less than 60Vdc, the power module meets all of therequirements for SELV. If the input voltage is a hazardous voltage that exceeds 60Vdc, theoutput can be considered SELV only if the following conditions are met:1) The input source is isolated from the ac mains by reinforced insulation.2) The input terminal pins are not accessible.3) One pole of the input and one pole of the output are grounded or both are kept floating.4) Single fault testing is performed on the end system to ensure that under a single fault,hazardous voltages do not appear at the module output.3320 Matrix DriveSuite 100Richardson, Texas 75082Phone (877) 498-0099 Toll Free(469) 916-4747Fax (877) 498-0143 Toll Free(214) 239-3101support@tdkinnoveta.comhttp://www.tdkinnoveta.com/Information furnished by TDK Innoveta is believed to be accurate and reliable.
