Description
The LW020 Single-Output-Series Power Modules are
low-prole 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 congura-
tions and grounding connections. Built-in ltering for
both input and output minimizes the need for external
ltering. The modules have a maximum power rating
of 20 W at a typical full-load efciency of up to 85%.

§ This product is intended for integration into end-use equipment.
All the required procedures for CE marking of end-use equip-
ment should be followed. (The CE mark is placed on selected
products.)
