NOTES
1. 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. Maximum output deviation is +10% inclusive of remote sense and trim. If remote sense is not being used the +SENSE should be connected to its
corresponding
+OUTPUT and likewise the -SENSE should be connected to its corresponding –OUTPUT.
3. The DCQAW100 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 connecting two aluminum electrolytic capacitors (Nippon chemi-con KY series, 220µF/100V) in
parallel.
- For 110VDC input models we recommend connecting three aluminum electrolytic capacitors (Ruby-con BXF series, 100µF/250V) in parallel.
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: DCQAW100-48S24R).
6. Optional heatsinks available. See page 5 for ordering details.
7. M3 x 0.5 threaded-thru inserts come standard. For Ø.126 thru-hole inserts add the suffix “TH” to the model number (Ex: DCQAW100-48S24TH). Models
with thru- hole inserts cannot be equipped with a heatsink.
8. BASE-PLATE GROUNDING: EMI can be reduced when you connect the case pin and the four screw bolts to the shield plane.
CAUTION: This power module is not internally fused. An input line fuse must always be used.

OUTPUT VOLTAGE
ADJUSTMENT
Output is adjustable for 10% trim up or -20% trim down of nominal output voltage by connecting an external resistor between the TRIM
pin and either the +SENSE or -SENSE pins. 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.
