The 1500 series 15 watts high performance DC/DC
converters are cost effective solution to the high reliability
and performance requirements of power distribution
systems in applications ranging from high speed data
communications equipment to industrial robotic systems.
The 1500 series operates over 2:1 input voltage ranges of
9 to 18, 18 to 36 or 36 to 72VDC; providing single, dual and
triple output combinations of 5, 12, 15, 5, 12, 15, 5/ 12 and
5/ 15 VDC. ꢀll models are pacꢁaged in compact, low profile
2” X 2” X 0.4” metal cases.
