BWS SERIES - 2.5 WATT
DESCRIPTION
BWS DC/DC converters offer excellent regulation and
isolation in an industry-standard DIP package. The BWS
is ideal for industrial, telecom, and networking
applications, and features short circuit protection, low
profile, and 500 VDC isolation. Please see the BWD series
for dual output applications.

Notes
1 Continuous short circuit protection is provided. Long-term continuous
operation in this mode is not recommended. Converter will auto-restart
once fault has been removed.
Specifications typically at 25°C, normal line, and full load, unless
otherwise stated.
Soldering Conditions: I/O pins, 260°C, ten seconds; fully compatible with
commercial wave-soldering equipment.
Safety: Agency approvals may vary from model to model. Please consult
factory for specific model information.
