| Output |
| Output Voltage |
220 V ± 1% isolation transformer output |
| Output Frequency |
Normal mains power (50 Hz ± 0.5 Hz): automatically synchronizes and tracks; Power failure: operates at 50 ± 0.5% of rated output |
| Phase Difference |
Under mains power supply, the phase difference between output and input is ≤2° |
| Waveform Distortion |
Under linear load, THD ≤ 2% |
| Transient Response |
Voltage variation range: ±3%, recovery time: 20 ms (linear load current: 0-rated value or rated value-0 step change) |
| DC Inverter Efficiency |
≥ 87% |
| AC Inverter Efficiency |
≥ 83% |
| Switching Period |
0 ms (switching between AC primary and DC mode), ≤3 ms (static bypass switching time) |
| Dynamic Response and Recovery |
Under a 100% load transient condition, the inverter's output transient voltage variation shall be ≥5%, and the output voltage must recover to within ±1% within 25 ms |
| Overload Capacity |
Overload alarms trigger at 100%-105%; for 105%-125%, the alarm persists for 10 minutes before switching to bypass; for 125%-150%, the alarm lasts 1 minute before switching to bypass; beyond 150%, the system switches to bypass within 1 second and removes overload self-recovery |
