Selection & installation notes
- Output current and power limits apply together, including when voltage is adjusted. Check low-input-voltage and temperature derating curves for the selected model.
- Connect protective earth and maintain vertical convection airflow. The source suggests20 mm above/below and5 mm at the sides; allow more beside hot equipment. Confirm terminal torque and wire size for the actual unit.
- Do not infer certified end-equipment compliance from referenced standards or logos. Request the exact model’s certification and verify EMC in the completed installation.
- A conformal-coating option does not make an open ventilated power supply waterproof.
- The NDR-150 photograph headline says120 W, while its label says24 V/6.5 A and the prose table gives156 W. Confirm the delivered unit’s approved rating; do not rely on the promotional headline.
- The general input-range paragraph conflicts with NDR-150’s170–240 VAC label. Verify its operating range and low-line power before using it on a120 V network.
- Original photos show larger outlines than the prose body dimensions. Confirm mounting and cable clearance against the delivered revision.
- The material table lists aluminum and galvanized steel, so the generic stainless-steel title is not used as a construction specification.
