ESCRIPTIONS
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 500μSec.
