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 configura-

tions 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%.
