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. TECHNICAL SPECIFICATIONS

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.
