TECHNICAL SPECIFICATIONS
OWS SERIES - 25 WATT
REV. 12/01
OWS single output DC/DC converters provide up to 25
Watts of output power in an industry-standard package
and footprint. The OWS features excellent efficiency,
six-sided shielding, and a fixed switching frequency. With
85°C case operation, the OWS is especially suited to
telecom, networking, and industrial applications. These
units are fully compatible with production board washing
processes.
