OWT SERIES - TRIPLE OUTPUT, 25 WATT
DESCRIPTION
OWT triple output DC/DC converters provide up to
25 Watts of output power in an industry standard 2” x 2”
package. OWT units feature excellent efficiency, five-
sided shielding, and fixed switching frequency. With
85°C case operation, the OWT is especially suited to
telecom, networking, and industrial applications.
