BWD SERIES - DUAL OUTPUT, 2.5 WATT

DESCRIPTION FEATURES

BWD dual output DC/DC converters offer excellent
regulation and isolation in an industry standard DIP
package. With several input voltage ranges, the BWD
is perfect for industrial, telecom, and networking
applications. The BWD features short circuit
protection, low profile, and 500 VDC isolation. Please
see the BWS series for single output applications.

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.
