Input Source Impedance: The power modules will operate to specifications without external components, assuming that the source voltage has very low impedance and reasonable input voltage regulation. Highly inductive source impedances can affect the stability of the power module. Since real-world voltage sources have finite impedance, performance is improved by adding an external filter capacitor. - For 24VDC & 48VDC input models we recommend using Nippon Chemi-con KY series, 100µF/100V. - For 110VDC input models we recommend using Ruby-con BXF series, 39µF/200V. 2. If remote sense is not being used, sense pins should connect to the output pins with same polarity. 3. The DCQAW150 series can only meet EMI Class A or Class B with external components added. Please contact factory for more information. 4. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. - For 24VDC & 48VDC input models we recommend with 2pcs of aluminum electrolytic capacitor (Nippon chemi-con KY series, 220µF/100V) - For 110VDC input models we recommend with 3pcs of aluminum electrolytic capacitor (Ruby-con BXF series, 100µF/250V). 5. Both positive logic and negative logic remote ON/OFF control is available. Positive logic remote ON/OFF comes standard; for negative logic remote ON/OFF add the suffix “R” to the model number (Ex: DCQAW150-48S24R). 6. Optional heatsinks available. See page 5 for ordering details. with thru-hole inserts cannot be equipped with a heatsink. 8. BASE-PLATE GROUNDING: EMI can be reduced when you connect two screw bolts to shield plane. CAUTION: This power module is not internally fused. An input line fuse must always be used.

With an external resistor between the TRIM and -SENSE pin, the output voltage set decreases. With an external between the TRIM and +SENSE pin, the output voltage set point increases. Maximum output deviation is +10% inclusive of remote sense. The value of the external resistor can be obtained by the equations below.

However, sufficient cooling should be provided to help ensure reliable operation of the unit. Heat is removed by condition, convection, and radiation to the surrounding environment. Proper cooling can be verified by measuring the point in the figure below. The temperature at this location should not exceed 105ºC. When operating, adequate cooling must be provided to maintain the test point temperature at or below 105ºC Although maximum point temperature of the power modules is 105ºC, you can limit this temperature to a lower value for extremely high reliability. ■ Thermal test condition with vertical direction by natural convection (20LFM) ■ The iron base-plate dimension is 19” x 3.5” x 0.063” (the height is EIA standard 2U) ■ The heat-sink is option and P/N: 7G-0029B-F, 7G-0030B-F, 7G-0031B-F, 7G-0032B-F BASE PLATE

An input line fuse must always be used. This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of sophisticated power architecture. To maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The suggested input line fuse is below.
