APPLICATIONS
The DBW series of DC/DC converters offers 40 Watts of output power in a 2 x 2 x 0.4 inch package. The DBW series has a 4:1 ultra wide
input range of 9-36VDC or 18-75VDC. This series also offers single and dual output models. Some features include 1600VDC isolation,
positive or negative remote on/off, and six-sided shielding. All models are short circuit, over voltage, over load, and over temperature
protected. Heatsinks are also available, please call factory for ordering details.
