ESCRIPTIONS
The 3000UR series is a family of compact 25W and 30W high
performance DC/DC converters specifically designed for
board mount power distribution applications where space is
critical, but performance and power cannot be sacrificed. 18
models operate over 4:1 input ranges of 10 to 40 or 18 to 72
VDC; providing single, dual or triple output combinations of
3.3, 5, 12, 15, ±5, ±12, ±15, 5±12 and 5±15 VDC. Standard
features include an input Pi filter to reduce reflected ripple
current, output voltage accuracy of ±1%, and a minimum
input/ output isolation voltage of 1400 VDC.
