Description
The QW030-Series Power Modules are dc-dc converters that operate over an input voltage range of 36 Vdc to
75 Vdc and provide precisely regulated dc outputs. The outputs are fully isolated from the inputs, allowing ver-
satile polarity configurations and grounding connections. The modules have maximum power ratings of 30 W
to 36 W at a typical full-load efficiency of up to 88%.
These encapsulated modules offer a metal case for optimum thermal performance. Threaded-through holes are
provided to allow easy mounting or addition of a heat sink for high-temperature applications. The standard feature
set includes remote sensing, output trim, and remote on/off for convenient flexibility in distributed power
applications.

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 device reliability.

Fusing Considerations
CAUTION: This power module is not internally fused. An input line fuse must always be used.
This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone
operation to an integrated part of a sophisticated power architecture. 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 normal-blow 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 for further information.
