TECHNICAL SPECIFICATIONS
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.
