Frequently asked questions about the EI20/6.1-0.35VA
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.
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.
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.
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.
