AZO Digital UPS-4000SR Uninterruptible Power Supply 4000VA/2000W Pure Sine Wave 12V DC to 230V AC Line-Interactive UPS with AVR

The AZO Digital UPS-4000SR is a high-performance line-interactive uninterruptible power supply designed to provide reliable backup power and voltage regulation for critical equipment. With a continuous output of 2000W and peak capacity of 4000VA, this UPS ensures your devices stay operational during power outages and fluctuations. Its pure sine wave output guarantees compatibility with sensitive electronics, while the built-in Automatic Voltage Regulation (AVR) stabilizes input voltage without draining the battery. Ideal for home offices, network equipment, servers, and industrial applications, the UPS-4000SR features an LCD display for real-time monitoring, intelligent fan cooling, and comprehensive protections against overload, short circuit, over-temperature, low battery, and over-voltage. The external battery design allows for flexible battery capacity expansion using standard 12V lead-acid batteries (AGM, Gel, or Flooded). With a transfer time of less than 10 ms, your equipment stays powered seamlessly.

Advantages
