To ensure proper, reliable operation, sufficient cooling of the power module is needed over the entire temperature range of the module. Convection cooling is usually the dominant mode of heat transfer. Hence, the choice of equipment to characterize the thermal performance of the power module is a wind tunnel. THERMAL CURVES Thermal Testing Setup Delta’s filter modules are characterized in heated vertical wind tunnels that simulate the thermal environments encountered in most electronics equipment. This type of equipment commonly uses vertically mounted circuit cards in cabinet racks in which the power modules are mounted. The following figure shows the wind tunnel characterization setup. The filter module is mounted on a test PWB and is vertically positioned within the wind tunnel. The space between the neighboring PWB and the top of the power module is 6.35mm (0.25”).

Figure 4 shows maximum output is a function of ambient temperature and airflow rate. To enhance system reliability, the power module should always be operated below the maximum operating temperature. If the temperature exceeds the maximum module temperature, reliability of the unit may be affected. 300LFM 1 0 25 35 45 55 65 75 85 Ambient Temperature (℃) Figure 6: Output Current vs. Ambient Temperature and Air Velocity @ Vin = 48V (Either Orientation) FACING PW B PW B MODULE AIR VELOCITY AND AMBIENT TEMPERATURE MEASURED BELOW THE MODULE AIR FLOW 50.8 (2.0”) 10 (0.4”) Note: Wind Tunnel Test Setup Figure Dimensions are in millimeters and (Inches) Figure 4: Wind tunnel test setup DS_FL75L07_11272006 3 APPLICATION Note: C2 & C3 can be 0.01μF to 0.1μF.

The Q48SB12025NR A module is one of the Delphi series quarter brick 12V, 25A DCDC converters. Measured noise is greatly dependent on layout, grounding, cable orientation, and load characteristics and the variation is possible from various application conditions. Figure 13.

Hence, the input positive (Vin+) and input negative (Vin-) labels could be swaped for the convenience of layout and matching with power module input connected to the filter module, just remember to swap the output labels accordingly as well.
