Technical Overview
This line interactive UPS features a transfer time of 6 milliseconds and maintains output voltage between 100-125V AC across an input range of 75-146V AC. The pure sine wave output ensures compatibility with sensitive electronic equipment, including active PFC power supplies found in modern servers and networking hardware.
The unit supports up to six external battery cabinets for extended runtime, increasing full load backup to 2.82 hours and half load to 6.38 hours. The LCD display provides real-time status monitoring, while USB (HID compliant) and network (RJ-45) ports enable management and monitoring capabilities. An EPO (Emergency Power Off) port adds safety integration.
The valve-regulated lead-acid battery is hot-swappable and replaceable, with a typical recharge time of 4 hours after complete discharge. The UPS operates on a single-phase 60 Hz input frequency and includes automatic voltage regulation (AVR) to correct brownouts and overvoltages without engaging the battery, extending battery life. The system is rated for maximum operation at 104°F (40°C) and storage between 5°F (-15°C) and 122°F (50°C).
