ESCRIPTIONS
The 1600 series 16 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 1600 series operates from wide (2:1) input voltage ranges
of 9 to 18, 18 to 36 or 36 to 72VDC; providing single, dual and
triple output combinations of 3.3, 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.
