DESCRIPTION
The DCQA150 series of DC/DC power converters provides up to 150 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 2:1 wide
input voltage ranges of 8.5-22VDC, 16.5-36VDC, and 33-75VDC. Some features include high efficiency up
to 92%, 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, and IEC60950-1 safety approvals. Several
different options are available for this series including negative logic remote ON/OFF, heatsinks, and thru-
hole inserts.
Applications:

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. We recommend using Nippon Chemi-con KY series,
100µF/100V.
2. Maximum output deviation is +10% inclusive of remote sense and trim. If remote sense is not being used, sense pins should connect to the output pins
with the same polarity.
3. The DCQA150 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. We recommend connecting 2pcs of aluminum
electrolytic capacitors (Nippon chemi-con KY series, 220µF/100V).
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: DCQA150-48S24R).
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: DCQA150-48S24TH). 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.
