ESCRIPTIONS
The 2100 series 20 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 2100 series operates over 2:1 input voltage ranges of
10 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.
