Description

The LW025 Single-Output-Series Power Modules are low-profile dc-dc converters that operate over an input voltage range of 36 Vdc to 75 Vdc and provide precisely regulated outputs. The output is isolated from the input, allowing versatile polarity configurations and grounding connections. The module has a maximum power rating of 25 W at a typical full-load efficiency of 79.

The power modules feature remote on/off and output voltage adjustments of 90 to 110 of the nominal output voltage. Built-in filtering for both input and output minimizes the need for external filtering.
