Reliability Temperature Rise (Burn-in): 85% to 95% load per unit, 40+/-5 degrees, 4 hours Leakage Current: 0.25mAMax240Vac Dielectric Withstand Voltage (between primary and secondary), 3000Vac, 60S, 5mAMax MTBF: according to MIL-HDBK-217F, full load, 25 degrees, over 50,000 hours 2. Protective Function Short Circuit Protection: the AC power supply can return to normal operation when the short circuit is removed Overcurrent Protection: when the overcurrent fault is removed, the AC power supply will automatically return to normal operation Overvoltage Protection: When the output voltage of the AC power supply exceeds 150%-180% of the rated voltage, the AC power supply enters the protection state, and the AC power supply can return to normal operation after the fault is corrected. 3. Environment Operating Temperature: 0-40 degrees under full load Storage Temperature: -20-85 degrees Humidity: 5% at 95% non-condensing
