DESCRIPTION
The WP30R 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 perfomance across all line and
load conditions. A ± 10% output trim feature is provided,
allowing the user to compensate for long line lengths. The
WP30R Series is assembled by a fully automated process us-
ing surface mount components for increased reliability. The
converters rugged, low-profile, aluminium housing provides
excellent EMI/RFI shielding. 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 (Available in Single Outputs)
•Over Current Protection
•Output Over Voltage Protection
•Output Voltage Adjust
APPLICATIONS
●TELECOMMUNICATION APPLICATIONS
