Key Features 

1. Line Interactive Technology: Provides enhanced protection from voltage fluctuations with automatic voltage regulation (AVR), which adjusts for under-voltage or over-voltage to maintain a stable output.
2. Capacity: Offers 850 VA / 480 W of power, ideal for smaller equipment or low-power devices.
3. Input Voltage Range: Supports 110/120 VAC or 220/230/240 VAC, with an input voltage range of 81-145 VAC (for 110/120 VAC) and 162-290 VAC (for 220/230/240 VAC), ensuring reliable operation even with fluctuating power sources.
4. Simulated Sinewave Output: Provides a simulated sinewave during battery mode, offering adequate protection for many types of equipment while reducing noise and harmonics.
5. Automatic Voltage Regulation (AVR): Stabilizes the input voltage, compensating for any fluctuations by boosting or bucking the voltage, maintaining a steady supply to your connected devices.
6. Fast Transfer Time: Ensures smooth transitions to battery power, with a typical transfer time of 2-6 ms and a maximum of 10 ms, minimizing disruptions to connected equipment.
7. Battery Type and Recharge Time: Uses a 12V/9Ah battery, with a typical recharge time of 4-6 hours to reach 90% capacity, ensuring quick recovery from power interruptions.
8. Protection Features: Provides comprehensive protection including overload, discharge, and overcharge protection to safeguard devices.
9. Smart Monitoring and Communication: Features an optional USB/RS-232 port for integration with monitoring software, compatible with major operating systems such as Windows, Linux, and MacOS.
10. Cold Start and Off-Mode Charging: Can be started even without AC power, and allows for charging when powered off, offering greater flexibility.
11. Environmental and Noise Specifications: Operates in environments with 0-90% humidity and a noise level of less than 40 dB, making it suitable for noise-sensitive spaces.
12. Alarms and Indicators: Includes both visual and audible indicators to alert users to various conditions such as battery mode, low battery, overload, and faults, with specific alarm patterns for each.

This UPS offers a compact, efficient, and versatile solution for providing backup power and surge protection for sensitive electronics, especially in small office or home environments.
