Description
The JW050A, JW075A, JW100A, and JW150A Power Modules are dc-dc converters that operat
voltage range of 36 Vdc to 75 Vdc and provide a precisely regulated dc output. The outputs are
from the inputs, allowing versatile polarity configurations and grounding connections. The modu
mum power ratings from 50 W to 150 W at a typical full-load efficiency of 84%.
The sealed modules offer a metal baseplate for excellent thermal performance. Threaded-through
vided to allow easy mounting or addition of a heat sink for high-temperature applications. The stand
includes remote sensing, output trim, and remote on/off for convenient flexibility in distributed pow

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These ar
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in
of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for exten
periods can adversely affect device reliability.

This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-a
operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, intern
ing is not included; however, to achieve maximum safety and system protection, always use an input line fus
safety agencies require a normal-blow fuse with a maximum rating of 20 A (see Safety Considerations sect
Based on the information provided in this data sheet on inrush energy and maximum dc input current, the s
type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data for further information.
