Notes
1. See derating curves for temperature and input curves.
2. Average efficiencies measured at 25%, 50%, 75% and 100% load with 230 VAC input.
3. For optional PCB only version, delete letter B from the model number e.g. SDU150PS24.
4. For optional 2 pin Molex input, add suffix ‘-D’ to model number e.g. SDU150PS24B-D.
5. At low line, 60% dip for 100 ms can meet performance criteria A with 50% load.
