SC-120W UPS power supply with charger switching power

Q: How much headroom should I leave on the power rating?

For continuous industrial duty plan on 20-30 % headroom above the measured load. For loads with high inrush, such as motors or capacitive input, allow more and check the surge rating rather than only the average current.

Q: Do these units accept 110 V and 230 V mains?

Input ranges are model-specific and shown in the specification table. Where a wide-range input is available it is stated; otherwise send your mains voltage and we will match the model.

Q: What protection features are built in?

Typical protection covers short circuit, over-current, over-voltage and thermal shutdown. The exact set is listed per model in the specification table above.

Q: Can you supply matching DIN-rail or enclosed versions?

Open-frame, enclosed and DIN-rail variants exist across this family. Send the model you are working from and we will confirm the equivalent mounting option.
