Energy storage system
Specification Details
1. Inrush Current: Cold start inrush current will not exceed 80A at 100-240Vac input and Max load at 25°C.
2. Average Efficiency: More than 87.40% at 115Vac and 230Vac input (tested at 25%, 50%, 75%, and 100% of max load).
3. No Load Power Loss: Less than 0.1W when input is 115Vac or 230Vac and output is no load.
4. Capacitance Load: Adapter turns on normally with 100~240Vac input and 470uF capacitance load, output in rated range.
5. Transient Response: Output voltage will not exceed 10% of nominal voltage (load fluctuation: 20% to 80%, R/S: 0.5A/uS, frequency: 100Hz, duration: 8mS at 80%).
6. Over Current Protection: 3.6A < I < 8A. Output enters hiccup mode under over-current, self-recovers after fault removal.
7. Short Circuit Protection: Input power decreases during output short circuit. Power supply remains undamaged and self-recovers.
8. Over Voltage Protection: Power supply triggers protection mode when output exceeds rated voltage.
9. Vibration Test: 10 to 300Hz sweep at constant acceleration of 1.0G (Breadth: 3.5mm) for 1 hour per perpendicular X, Y, Z axis.
10. Drop Test: Height: 1m; fell 3 times on a plank of at least 53mm thickness placed on non-flexible cement ground.
11. EMI Compliance: FCC Part18 class B, EN55032.
12. EMS Compliance: EN55035.
13. Safety Accordance: ANSI/AAMI ES60601-1, CSA C22.2 NO. 60601-1, IEC60601-1, EN60601-1, AS/NZS 60601.1.
