Koiri 6 KVA 1:1 Phase 192 VDC On-Line UPS with Inbuilt Isolation Transformer & 100-110 Minutes Back up

The Koiri 6 KVA 1:1 Phase On-Line UPS with 98 Minutes Backup is a premium, double-conversion (on-line) UPS unit designed to provide extended autonomous operation during power outages. In this configuration, the UPS continuously converts incoming AC power to DC and then back to AC (1:1 phase), effectively isolating your load from input voltage fluctuations, surges, sags, and noise. With a full 6 kVA (˜4.8 kW at 0.8 PF) capacity, this model can support fairly heavy loads such as servers, telecom systems, laboratory instruments, and industrial controls. What distinguishes this version is its longer backup time: 98 minutes under specified load conditions (often at partial load). This implies a large battery bank (higher Ah rating or more cells) and efficient power management to sustain operations nearly 1 hour 38 minutes in the absence of mains power. The unit will typically include features such as: LCD or LED status display for voltage, current, load, battery status Protection against overload, short circuit, deep discharge Battery management to extend battery life Possibly an inbuilt isolation transformer to further filter out line disturbances High efficiency (often > 90 % or more) under normal load Wide input voltage range tolerance to reduce battery switching Because achieving 98 minutes backup at full load is challenging, the specified runtime is usually guaranteed at a fraction of full load (e.g. 40–60 % load). The actual runtime you experience will depend on your installed load, battery health, ambient conditions, and how conservatively the system is operated.
