The BWD dual output series of 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 shortcircuit
protection, low profile, and 500VDC of isolation. Please see the BWS series for single
output applications. The BWD is manufactured in IPD’s ISO9001 factory.

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.
Specifications subject to change without notice.
