| Case operating temperature |
Tcase −40 to +85°C; maximum case temperature +85°C. This is not the ambient-temperature limit. |
| Cooling and ambient derating |
Horizontal mounting and free-air convection. At 200 VAC, 100% load through +45°C, then 60% at +50°C; at 230 VAC, 100% through +50°C, then 60% at +55°C; above 277 VAC, 100% through +55°C, then 60% at +60°C. The curves stop at these endpoints. At rated current in the constant-power region, maximum workable ambient temperature is +50°C typical at 230 VAC. |
| Case-temperature load curve |
The horizontal-mounting case-temperature curve shows 100% load through +85°C and stops there. Observe both case and ambient limits. |
| Altitude derating |
Above 2000 m (6500 ft), reduce allowable ambient temperature by 3.5°C per additional 1000 m for this fanless driver. |
| Humidity and storage |
Working: 20–95% RH, non-condensing. Storage: −40 to +80°C and 10–95% RH, non-condensing. |
| Vibration |
10–500 Hz, 5G; 12 minutes per cycle; 72 minutes along each X, Y and Z axis. |
| Typical lifetime |
>50,000 hours when Tcase, particularly the tc / TMP point, is about +80°C or less. Lifetime varies with temperature; use the dedicated curve, not an unconditional service-life guarantee. |
| MTBF |
728.1K h minimum, Telcordia SR-332 (Bellcore); 60.2K h minimum, MIL-HDBK-217F at 25°C |
| Warranty |
