DESCRIPTION

The DCQAW150 series of DC/DC power converters provides up to 132 Watts of output power in a 2.28” x

1.45” x 0.5” industry standard quarter-brick package. This series has single output models with 4:1 wide input

voltage ranges of 8.5-36VDC, 16.5-75VDC, and 40-160VDC. Some features include high efficiency up to 90%,

2250VDC I/O basic insulation, and remote ON/OFF control. These converters are also protected against input

under voltage, short circuit, over voltage, over load, and over temperature conditions. All models are RoHS

compliant and have UL60950-1, EN60950-1, IEC60950-1, EN45545-2 and EN50155 safety approvals. Several

different options are available for this series including negative logic remote ON/OFF, heatsinks, and thru-hole

inserts.

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. 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.

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: DCQAW150-48S24TH). Models

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.
