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