DESCRIPTIONS
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).
