Description

The JW050F, JW075F, JW100F, and JW150F 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 99 W at a typical full-load efficiency of 80%.

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.

The JW050F, JW075F, JW100F, and JW150F Power Modules

use advanced, surface-mount technology and deliver high-

quality, efficient, and compact dc-dc conversion.
