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 out-
put voltage. Built-in filtering for both input and output minimizes the need for external filtering.
