| Case and ambient limits |
Operating case temperature: −40 to +90°C, with maximum Tcase +90°C. Horizontal installation: at 180 VAC, 100% load from −40 to +50°C, then 60% at +60°C; at 230 VAC, 100% through +55°C, then 60% at +65°C; above 277 VAC, 100% through +60°C, then 60% at +70°C. The case-temperature load curve shows 100% from −40 to +90°C. Meet both case and ambient limits; free-air convection cooling. |
| Input and altitude derating |
The 60 Hz static graph shows 100% load from 180 to 528 VAC; the notes still require assessment of low-input derating. Follow the separate voltage-dependent ambient-temperature curves. Above 2,000 m altitude, reduce allowable ambient temperature by 3.5°C per 1,000 m for this fanless design. |
| Environment |
Working humidity: 20–95% RH, non-condensing. Storage: −40 to +80°C, 10–95% RH. Temperature coefficient: ±0.03%/°C over 0–60°C. Vibration: 10–500 Hz, 5 G, 12 min/cycle, 72 min along each X, Y and Z axis. |
| Operating curves |
PFC switching frequency 45 kHz; PWM switching frequency 65 kHz. PF curves use Tc 80°C; THD and efficiency examples use the 700 mA model at Tc 80°C, distinguishing 230, 277, 347 and 480 VAC. These examples do not guarantee identical performance for every current option. |
| Life and reliability |
Typical lifetime >50,000 hours at Tc / TMP about 80°C or lower. The lifetime graph indicates approximately 100,000 h at Tc 20–70°C, 70,000 h at 75°C, 50,000 h at 80°C, 35,000 h at 85°C and 25,000 h at 90°C. MTBF: 1769.1K hours minimum, Telcordia SR-332 (Bellcore); 145.2K hours minimum, MIL-HDBK-217F at 25°C. |
| Warranty |
Five-year manufacturer warranty, subject to its warranty statement and the specified operating conditions. |
