Parallel Diode
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.

Ripple Current
Reverse Voltage Protection
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.
