A SELV reliability test is conducted on the system where the module is used in combination with the module to ensure that under a single fault hazardous voltage does not appear at the module s output When installed into a Class equipment without grounding spacing consideration should be given to the end use installation as the spacing between the module and mounting surface have not been evaluated The power module has extra low voltage ELV outputs when all inputs are ELV This power module is not internally fused To achieve optimum safety and system protection an input line fuse is highly recommended The safety agencies require a normal blow fuse with 5A maximum rating to be installed in the ungrounded lead A lower rated fuse can be used based on the maximum inrush transient energy and maximum input current DS V48SR15004 06122007 Soldering and Cleaning Considerations Post solder cleaning is usually the final board assembly process before the board or system undergoes electrical testing Inadequate cleaning and or drying may lower the reliability of a power module and severely affect the finished circuit board assembly test Adequate cleaning and or drying is especially important for un encapsulated and or open frame type power modules For assistance on appropriate soldering and cleaning procedures please contact Delta s technical support team D FEATURES DESCRIPTIONS Over Current Protection
