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. All models are packaged in compact, low profile

2” X 2” X 0.4” metal cases.
