ESCRIPTIONS
The 100FR series is a family of cost effective, yet high
performance 1 Watt DC/DC converters. These converters
combine miniature packaging in a 24-pin DIP compatible
case with high performance features such as 500 VDC
input/output isolation voltage, continuous short circuit
protection with automatic restart and tight line/load regulation.
Units operate from power busses of 5 and 12 and provide
output voltage levels of 5, 12, 15 , ±12 and ±15 VDC.
