Description
The LW020 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 outputs are isolated
from the input, allowing versatile polarity configurations and grounding connections. Built-in filtering for
both input and output minimizes the need for external
filtering. The modules have a maximum power rating
of 20 W at a typical full-load efficiency of up to 85%.
