The 1000WFR series is a family of 10W single and dual

output DC/DC converters that utilize a cost effective design

to achieve high levels of performance. Operating from wide

(2:1) input voltage ranges of 9 to 18, 18 to 36 or 36 to 72 Vdc;

providing outputs of 5, 9, 12, 15, ±12 or ±15 Vdc.

Standard features include an input Pi filter to reduce

reflected ripple current, efficiency as high as 80%, and

continuous output short circuit protection. Input/output

isolation is 500 Vdc minimum, output voltage accuracy is ±1%

and transient response is less than 500

μSec.
