DATASHEET
KNW013/020-88 Series Power Modules;
DC-DC Converters
36 – 75Vdc Input; 3.3 to 5.0Vdc Output; 13 to 20A Output Current
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.

Technical Specifications
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. 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.

CAUTION: This power module is not internally fused. 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 manufacturer’s data sheet for further information.
