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. ꢀtandard
features include an internal Pi filter to reduce reflected
ripple current, efficiency as high as 82% and low noise
operation (20 mV Pk-Pk).
