II. Output Characteristics:
1-1: AC voltage range: 110 VAC ±10%
1-2: AC output frequency: 60 Hz ± 1%
1-3: Continuous Output Power: 2000W
1-4: Overload Protection: 2200W–3000W
1–5: Peak output power: 4000 W (incandescent lamp), sustained for 1–3 seconds, then shut off.
1-6: Output Voltage Waveform: Pure Sine Wave
1–7: Total Harmonic Distortion: ≤10%
1-8: Efficiency: ≥88%
1–9: Output short-circuit protection: Provides protection; after the short circuit is cleared, the power must be restarted to resume operation.

1-4: Operating relative humidity: 10–90%
1-5: Storage relative humidity: 5–95%
High-Voltage Test/Hi-Pot Test:
The high‑voltage test shall meet the requirements specified in the table below. All products are tested online, with each test maintained for at least 5 seconds, and no failures shall occur.
Input—Output Primary to Secondary 1500Vac/5mA/60s No arcing
Input—Ground Primary to P.G No breakdown No broken
Output--Location Secondary to P.G
V. Insulation Resistance
ITEM SPECIFICATION REMARK
Input–Output Primary to Secondary >10 MΩ; DC 500 V
Input—Ground Primary to P.G
6. AC Leakage Current:
When the output voltage is 110 Vac, the maximum leakage current is 0.25 mA.
VII. Reliability Requirements:
1. Aging
The product must undergo a burn-in test for 2–4 hours in an environment of 40°C ± 5°C under 100% rated load.
2. Mean Time Between Failures Estimation / MTBF Qualification
Mean Time Between Failures: 30,000 hours, under ambient conditions of 25°C and at rated input and full load.
