medical and process control.
Applications
Twenty-one models available. Three
input voltage ranges of 9-18 Vdc, 18-36
Vdc and 36-75 Vdc provide regulated
outputs of 3.3, 5, 12, 15 and ±5, ±12
and ±15 Vdc.
These high performance 15 watt
converters offer a high switching
frequency topology, 1500 Vdc I/O
isolation, and efficiencies to 85%.
he SC15A series of cost
sensitive single and dual output
15 watt DC/DC converters are
specifically designed for critical appli-
cations requiring a compact, low profile
case.

Dimensions and Connections
NOTES:
1. Ripple measured with a 3.3 µF tantalum
capacitor across each output.
2. Minimum load 10% of full load. Load regulation
from full load to minimum load.
3. The SC15A series requires an external filter
capacitor across the input valued at 2.2µF @
100Vdc such as ITW/Paktron part# 225K100RA4
or equiv.
4. Case connected to pin #1 on -48 models. Case
connected to pin #2 on -12 and -24 models
