The 500 series is a family of compact, high performance, low

noise 5W DC/DC converters. High performance features

include 1000 VDC input/output isolation, continuous short

circuit protection with automatic restart and a maximum

line/load regulation of only ± 0.03%. Thirty-six models operate

from power busses of 5, 12, 18, 24, 28 or 48 VDC and provide

single or dual output of 5, 12, 15, ±5, ±12 or ±15 VDC. Standard

features include an internal Pi filter to reduce reflected

ripple current, efficiency as high as 82% and low noise

operation (20 mV Pk-Pk).
