DESCRIPTIONS
The 1500UR series is a family of miniature 15W DC/DC
converters specifically designed for board mount power
distribution applications where space is critical, but
performance and power cannot be sacrificed. Standard
features include an ultra-wide 4:1 input voltage range,
efficiency as high as 83% and continuous short circuit
protection by input current limiting. 14 models operate from
(4:1) input voltage ranges of 10 to 40 VDC or 18 to 72 VDC and
provide tightly regulated outputs of 3.3, 5, 12, 15, ±5, ±12 or
±15 VDC. All models are packaged in a compact, low profile
2” X 2” X 0.4” metal case.
