DS_S48SA05006_09252012 DESIGN CONSIDERATION 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 sou rce 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 designe d 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 desig n. Application notes to assist designers in addressing these issues are pending release. Safety Considerations The power module must be installed in compliance with the spacing and separation requirements of the end - user’s safety agency standard if the system in which the power module is to be used must meet safety agency requirements. When the input source is 60Vdc or below, the power module meets 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 must be insulated from any hazardous voltages, including the ac mains, with reinforced insulation. One Vi pin and one Vo pin are grounded, or all the input and output pins are kept floating. The input terminals of the module are not operator accessible. A SELV reliability test is conducted on the system where the module is used to ensure that under a single fault, hazardous voltage does not appear at the module’s output. Do not ground one of the input pins without grounding one of the output pins. This connection may allow a non - SELV voltage to appear between the output pin and ground. This power module is not internally fused. To a chieve optimum safety and system protection, an input line fuse is highly recommended. The safety agencies require a normal -blow fuse with 3A maximum rating to be installed in the ungrounded lead. A lower rat ed fuse can be used based on the maximum inrush transient 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 re liability 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.
