KNW Series

66 Watt | 20 Amp | 1/16 Brick
 

KNW013-020 series DC-DC converters, a very low cost, high power line of DC-DC power modules, designed for regulated single output voltages of 5.0Vdc and 3.3Vdc in an industry standard sixteenth brick package. These open-frame modules operate over a wide input voltage range of 36 to 75Vdc . The output is fully isolated from the input, allowing versatile polarity configurations and grounding connections. Bonus features include remote On/Off, output voltage adjustment, remote sense, overvoltage/current protections and overtemperature protection and the option of through-hole or surface mount packaging.
