Description
The JAHW050F, JAHW075F, and JAHW100F 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 33 W to 66 W at a typical full-load efficiency of 88%.
The sealed modules offer a metal baseplate for excellent thermal performance. Threaded-through holes are
provided to allow easy mounting or addition of a heat sink for high-temperature applications. The standard fea-
ture set includes remote sensing, output trim, and remote on/off for convenient flexibility in distributed power
applications.
