Safety Project

Safety Project

• Static electricity: In the mode of contact discharge at ±8kV and discharge in the air at ±15kV, discharge 10 times in all parts correctly;
• Pressure test: At 25 °C environment, add AC3000V, maximum 5mA between AC input plug and DC plug for 1 minute, the charger without damage, arc discharge, insulation damage and other abnormalities;
• Insulation resistance: At 25 °C environment, add DC500V between AC input plug and DC plug for 1 minute, the insulation impedance more than 7MΩ;
• Leakage current: Maximum 0.25mA when input.
• Temperature: At normal temperature 30 ℃, apply 100-240V input, output 450 mA, temperature for all the shell surface below 55 ℃;
• Continuous working hours: At the rated voltage and the output current 450mA for 96 hours, there is no damage to the charger;
• MTBF: At 25 ℃ during normal input, the output is 80% maximum load, 90% cases the MTBF for the charger is 50000 hours.
