| Protection functions |
Short-circuit, overload, overvoltage and input-polarity protection are listed in the series features. |
| Overload protection |
105–150% of rated output power. Hiccup mode; automatic recovery after the fault condition is removed. |
| Overvoltage protection |
27.6–32.4 V. The output shuts off and is clamped by a zener diode. |
| Cooling |
Free-air convection. |
| Working temperature |
−10 to +60°C; apply the appropriate load-derating curve. |
| Ambient-temperature load curve |
Horizontal mounting: 80% load at −10°C, 100% from 0 to +50°C, and 60% at +60°C. Vertical mounting: 80% at −10°C, 100% from 0 to +45°C, and 60% at +55°C. Follow the corresponding curve between the marked points. |
| Working humidity |
20–95% RH, non-condensing. |
| Storage conditions |
−20 to +85°C; 10–95% RH. |
| Temperature coefficient |
±0.05%/°C over 0–50°C. |
| High-altitude derating |
For this fanless supply, reduce the allowable ambient temperature by 3.5°C per 1000 m above 2000 m altitude. |
| Vibration |
10–500 Hz, 2 G, 10 minutes per cycle; 60 minutes along each of the X, Y and Z axes. |
