Energy Storage System
Detailed Performance Specifications
| Input & Efficiency Parameters | |
| Input Voltage Range | 198Vac to 264Vac (Single Phase) |
| Inrush Current (Cold Start) | Will not exceed 160A at 220Vac input and Max load (at 25℃) |
| Full Load Efficiency | ≥ 85.00% at 230Vac input |
| Capacitance Load | Under 220Vac CV Mode with 470uF load, the charger starts normally and constant current remains in rated range. |
| Output & Protection Parameters | |
| Output Load Transient Response | Output shall not exceed 10% of nominal voltage under load fluctuations from 20% to 80%, R/S 0.5A/uS, 100Hz frequency, and 8mS duration at 80%. |
| Over Current Protection | I ＞ 3.1A. Output enters hiccup mode under overcurrent conditions and self-recovers once the fault is removed. |
| Short Circuit Protection | Input power decreases during a short circuit; no damage to power supply, with automatic self-recovery. |
| Over Voltage Protection | Built-in protection triggers when the output exceeds nominal voltage limits. |
| Reliability, Environmental & Safety | |
| Vibration Resistance | 10 to 300Hz sweep at a constant acceleration of 1.0G (Amplitude: 3.5mm) for 1 hour on X, Y, Z perpendicular axes. |
| Burn-in Test | Minimum 4 hours under normal input and 80% rated load at 40℃ ± 5℃. |
| MTBF Qualification | Minimum 50,000 hours at 25°C under full load and nominal input conditions. |
