Selection & installation notes
- The original chart lists only the 40 A integrated TDR. Prose additionally offers 15/25 A TDR and 24–280 VAC/random variants; obtain an exact datasheet before ordering those extensions.
- Input current and TDR dimensions differ between prose and technical images. Confirm driver capacity, mechanical clearance and actual thermal configuration.
- The threshold rows specify ON ≤4 V and OFF ≥1 V as threshold limits; they are not instructions to drive ON below 4 V or hold OFF above 1 V. Confirm guaranteed logic levels with the manufacturer.
- TDR/TNR are AC-output products. Generic MOSFET/DC-output and DC-lamp diagnostic instructions on the source page are not applicable to their normal operation.
- Coordinate semiconductor protection, maximum phase current and thermal derating. TNR needs a separately designed heatsink; its ratings cannot inherit TDR cooling conditions. Provide upstream isolation because OFF leakage remains.
