DESCRIPTIONS
INPUT CHARACTERISTICS
The 800 series is family of miniature, high performance and
high reliability DC/DC converters. The 800 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. Standard
features include 500VDC input/output isolation, efficiency
as high as 82%, tight line/load regulation and low output
ripple and noise. All 24 models are packaged in compact,
low profile 1” X 2” X 0.38” metal cases.
