The JBW050A Power Module is a dc-dc converter that operates over an input voltage range of 36 Vdc to 75
Vdc and provides a precisely regulated 5 Vdc output. The output is fully isolated from the input, allowing a
versatile polarity configuration and grounding connections. The module has a maximum power rating of 50 W
at a typical full-load efficiency of 84%.
The modules are DC board-mountable and encapsulated in metal cases. 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.
