The JW050B, JW075B, JW100B, and JW150B Power Modules are dc-dc converters that operate over an input
voltage range of 36 Vdc to 75 Vdc and provide a precisely regulated dc output. The outputs are fully isolated
from the inputs, allowing versatile polarity configurations and grounding connections. The modules have maxi-
mum power ratings from 50 W to 150 W at a typical full-load efficiency of 88%.
The sealed modules offer a metal baseplate for excellent thermal performance. Threaded-through holes are pro-
vided 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.
