I. Input Characteristics:
1-1: Rated input voltage 22.2 VDC
1-2: Input voltage range: 18–25.2 VDC
1-3: Operating voltage range: 19.2–25.2 VDC
1-4: Low-Voltage Shutdown: 18±0.4 VDC
1-5: Low-Voltage Recovery: 19.2±0.4 VDC
1-6: High-voltage cutoff relay: 26 ± 0.4 VDC
1-7: High-Voltage Restart: 25.2 ± 0.4 VDC
1-8: No-load current: ≤0.7A
1–9: Input fuses: 30A × 4
II. Output Characteristics:
1-1: AC voltage range: 110 VAC ±10%
1-2: AC output frequency: 60 ± 0.3 Hz
1-3: Continuous Output Power: 1000W
1–4: Overload Protection: 1200 W–1300 W (for purely resistive loads, continuous operation for 18–22 seconds before shutdown)
1–5: Peak output power: 2000 W, sustained for 18–22 seconds before shutdown (under purely resistive load).
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.
1–10: Overtemperature Protection: DC side: 95±5°C, AC side: 85±5°C
1–11: The fan starts cooling when the load power reaches 50% of the rated power or the temperature reaches 40°C; the fan shuts off when neither condition is met.
III. Other Features:
1-1: Explanation
Normal operation; green LED
Fault: Red LED
1-2: Operating temperature range: -10 to 40°C
1-3: Storage temperature range: -20 to 55°C
1-4: Operating relative humidity: 10–90%
4. High-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
1.1. Aging
The product must undergo a burn-in test for 2–4 hours in an environment of 40°C ± 5°C and under 100% rated load.
1.2. Estimation of Mean Time Between Failures
Mean Time Between Failures: 30,000 hours, under ambient conditions of 25°C and at rated input and full load.
