Description
The LUW025-Series Power Modules are low-profile, open-frame dc-dc converters that operate over an input
voltage range of 36 Vdc to 75 Vdc and provide a precisely regulated output. The output is isolated from the
input, allowing versatile polarity configurations and grounding connections. The modules feature remote on/off
and a wide range of output voltage adjustments. Built-in filtering for both input and output minimizes the need
for external filtering.
