DATASHEET KNW013/020-88 Series Power Modules DC-DC Converters 36 75V Input 3.3 to 5.0V Output 13 to 20A Output Current dc dc RoHS Compliant Description The KNW013/020-88 (Sixteenth-brick) series power modules are isolated dc-dc converters that operate over a wide input voltage range of 36 to 75Vdc and provide a single precisely regulated output. The output is fully isolated from the input, allowing versatile polarity configurations and grounding connections. The modules exhibit high efficiency, typical efficiency of 91% for 3.3V/20A. These open frame modules are available either in surface-mount (-SR) or in through-hole (TH) form.

These are absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect the device reliability.

An input line fuse must always be used. This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of sophisticated power architectures. To preserve maximum flexibility, internal fusing is not included, however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a time-delay fuse with a maximum rating of 5 A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturers data sheet for further information. Page 2 2021 ABB. All rights reserved.
