| Working case temperature |
Tcase −25 to +85°C; maximum case temperature 85°C. This is a case limit, not the ambient operating limit. |
| Ambient temperature / load |
Horizontal mounting: the 100% load boundary runs from −25°C to +40°C at 110 VAC and to +50°C at 230 VAC for this output type. The plotted boundaries end vertically; they do not authorize operation beyond those limits. |
| Case-temperature / load |
The horizontal-mounting plot shows 100% load up to Tcase 85°C. Apply case, ambient, input and output limits together. |
| Low-input derating |
Static characteristic at 60 Hz: approximately 80% load at 100 VAC, rising to 100% at 110 VAC; 100% from 110 to 305 VAC within thermal limits. |
| Cooling and altitude |
Free-air convection. Above 2000 m, derate the allowed ambient temperature by 3.5°C per additional 1000 m for this fanless model. |
| Working and storage humidity |
Working: 20–90% RH, non-condensing. Storage: −40 to +80°C, 10–95% RH. |
| Temperature coefficient |
±0.03%/°C over 0–50°C. |
| Vibration |
10–500 Hz, 2G; 10 minutes per cycle, 60 minutes each along X, Y and Z axes. |
| Life expectancy |
>50,000 hours typical when the marked Tc point is about 70°C or less; a temperature-dependent expectation, not a guaranteed service-life duration. |
| Performance curves |
THD, PF and efficiency plots use the H model at Tcase 75°C, with 700 mA and 1050 mA settings. Do not apply these curves as fixed-voltage-model guarantees. |
