To preserve maximum flexibility, internal fusing is not included, however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a 20A, fast-acting, glass type fuse rated for 32V (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used.

First, there may be a need to further reduce the requirements of safety extra-low voltage (SELV), the input must output ripple and noise of the module. Second, the dynamic meet SELV requirements. The power module has extra-low response characteristics may need to be customized to a voltage (ELV) outputs when all inputs are ELV. particular load step change. The input to these units is to be provided with a fast-acting fuse with a maximum rating of 20A in the positive input lead. To reduce the output ripple and improve the dynamic response to a step load change, additional capacitance at the output can be used. Low ESR polymer and ceramic capacitors are recommended to improve the dynamic response of the module.

When the Remote Sense feature is not being used, connect the Remote Sense pin to the output pin of the 1.2 0.6240 module. 1.5 0.5731 1.8 0.5221 Rdistribution Rcontact Rcontact Rdistribution 2.5 0.4033 V (+) V IN O 3.3 0.2670 Sense R LOAD By a using 1% tolerance trim resistor, set point tolerance of ±2% is achieved as specified in the electrical specification. The R R R R distribution contact contact distribution POL Programming Tool, available at www.gecriticalpower.com COM COM under the Design Tools section, helps determine the required external trim resistor needed for a specific output voltage. Figure 32. Remote sense circuit configuration Voltage Margining Output voltage margining can be implemented in the Austin TM SuperLynx modules by connecting a resistor, Rmargin-up, from the Trim pin to the ground pin for margining-up the output voltage and by connecting a resistor, Rmargin-down, from the Trim pin to the Output pin for margining-down. Figure 31 shows the circuit configuration for output voltage margining. The POL Programming Tool, available at www.gecriticalpower.com under the Design Tools section, also calculates the values of and R for a specific output voltage and % Rmargin-up margin-down margin.

Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel. The test set-up is shown in Fig. 33. Note that the airflow is parallel to the long axis of the module as shown in Fig. 34. The derating data applies to airflow in either direction of the module’s long axis. Figure 34. T Temperature measurement location ref 25.4_ Wind Tunnel (1.0) Post solder Cleaning and Drying PWBs Considerations Power Module Post solder cleaning is usually the final circuit-board assembly process prior to electrical board testing. The result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit-board assembly. For guidance on appropriate soldering, 76.2_ cleaning and drying procedures, refer to Board Mounted Power (3.0) Modules: Soldering and Cleaning Application Note. x Through-Hole Lead-Free Soldering Information Probe Location for measuring 5.97_ The RoHS-compliant through-hole products use the SAC airflow and (0.235) ambient (Sn/Ag/Cu) Pb-free solder and RoHS-compliant components. temperature They are designed to be processed through single or dual wave soldering machines. The pins have an RoHS-compliant finish Air that is compatible with both Pb and Pb-free wave soldering flow processes. A maximum preheat rate of 3°C/s is suggested. The wave preheat process should be such that the temperature of the power module board is kept below 210°C. For Pb solder, Figure 33. Thermal Test Set-up. the recommended pot temperature is 260°C, while the Pb-free solder pot is 270°C max.

The output power of the module should not exceed the rated power of the module (Vo,set x Io,max). Please refer to the Application Note “Thermal Characterization Process For Open-Frame Board-Mounted Power Modules” for a detailed discussion of thermal aspects including maximum device temperatures. Heat Transfer via Convection Increased airflow over the module enhances the heat transfer via convection. Thermal derating curves showing the maximum output current that can be delivered at different local ambient temperature (T ) for airflow conditions ranging A from natural convection and up to 2m/s (400 ft./min) are shown in the Characteristics Curves section.
