DS_E24SR12005_10282013 Safety Considerations The power module must be installed in compliance with the spacing and separation requirements of the end-user’s safety agency standard, i.e., UL60950, CAN/CSA-C22.2 No. 60950-00 and EN60950: 2000 and IEC60950-1999, if the system in which the power module is to be used must meet safety agency requirements. Basic insulation based on 75 Vdc input is provided between the input and output of the module for the purpose of applying insulation requirements when the input to this DC -to-DC converter is identified as TNV -2 or SELV. An additional evaluation is needed if the source is other than TNV-2 or SELV. When the input source is SELV circuit, the power module meet s SELV (safety extra -low voltage) requirements. If the input source is a hazardous voltage which is greater than 60 Vdc and less than or equal to 75 Vdc for the module’s output to meet SELV requirements, all of the following must be met:  The input source m ust be insulated from the ac mains by reinforced or double insulation.  The input terminals of the module are not operator accessible.  If the metal baseplate is grounded , one Vi pin and one Vo pin shall also be grounded.  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 II equipment (without grounding), spacing consideration shou ld 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 15A maximum rating to be installed in the ungrounded lead. A lower rated fuse can be used based on the maximum inrush transien t energy and maximum input current. 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 procedu res, please contact Delta’s technical support team. DESIGN CONSIDERATIONS Input Source Impedance The impedance of the input source connecting to the DC/DC power modules will interact with the modules and affect the stability. A low ac -impedance input source is recommended. If the source inductance is more than a few μH, we advise adding a 10 to 100 μF electrolytic capacitor (ESR < 0.7 Ω at 100 kHz) mounted close to the input of the module to improve the stability. Layout and EMC Considerations Delta’s DC/DC power modules are designed to operate in a wide variety of systems and applications. For design assistance with EMC compliance and related PWB layout issues, please contact Delta’s technical support team. An external input filter module is available for easier EMC compliance design. Below is the reference design for an input filter tested with E24SR12005XXXX to meet class B in CISSPR 22.
