ESCRIPTIONS
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).

2. Case D pinning is standard. Case D model numbers do not require suffixing.
3. Case D1 pinning is optional. Case D1 model numbers must be suffixed with “D1”. Example: 505S48-D1
All specifications are typical at nominal input, nominal load and 25
°
C unless otherwise specified.
External, low ESR, 10 microfarad (minimum) capacitor across output is recommended for operation.
