Description
The SW/SC series power modules are isolated dc-dc converters that operate over a wide range of input voltage (VIN
= 18 - 36Vdc for SC modules and VIN = 36 – 75Vdc for SW modules) and provide a single precisely regulated
output. This series is a low cost, smaller size alternative to the existing LW/LAW/LC with enhanced performance
parameters. The output is fully isolated from the input, allowing versatile polarity configurations and grounding
connections. The modules exhibit high efficiency, typical efficiency of 86% for 5.0V/3A. Built-in filtering for both
input and output minimizes the need for external filtering.
