The WPN30R Series is a family of
high performance DC/DC
converters. The unit is housed in a
space-saving shell and combines
low cost with high performance
across all line and load conditions.
An output trim feature is provided,
allowing the user to compensate
for long line lengths. The
WPN30R Series is assembled by a
fully automated process using
surface mount components for
increased reliability. Through-
holes are provided to simplify unit
mounting or the addition of a
heatsink for high temperature
applications. Other features
include:
Full Regulation Down to Zero
Load
Under Voltage Lock-Out, Auto-
Start
Internal Temperature Shutdown,
Auto-Reset
Soft Start
Remote On/Off (Available in
Positive or Negative Logic)
Remote Sense
