UPS System On Line UPS
The Koiri 7.5 KVA 1:1 Phase On-Line UPS with 15-20 Minutes Backup is a high-reliability double-conversion UPS designed for critical loads in commercial or industrial settings. With a capacity of 7.5 kVA (˜ 6 kW at 0.8 power factor), it uses online (true double-conversion) topology so that the load is always running off inverter output — thus isolating it from input voltage fluctuations, surges, frequency changes, and discontinuities. This model provides around 18 minutes of battery backup time under a specified load, making it suitable for short power interruptions, bridging the gap until generator power kicks in or for safely shutting down sensitive equipment. It features an inbuilt isolation transformer (optional in some variants) for further protection, LCD/LED display for monitoring load, battery status, and alarms, protections against overload, short circuits, deep discharge of batteries, and likely automatic bypass in case of UPS failure. Expected efficiency is moderate to high (often above ~85–90%) under near rated load, with a wide input voltage/frequency range to reduce battery reliance under fluctuating mains.
