KT Series Online UPS (120–250kVA) – Three Phase Input / Three Phase Output

The KT Series Online UPS (120–250kVA) Three Phase Input / Three Phase Output is an advanced power protection system designed to deliver stable and uninterrupted power for large industrial and mission-critical environments. Built with true online double-conversion technology, the UPS continuously converts incoming power to ensure a clean and regulated output supply.

The system incorporates 3-level IGBT rectifier and inverter technology, which improves efficiency, reduces energy losses, and ensures stable pure sine wave output with low harmonic distortion. With a high input power factor (≥ 0.99) and low Total Harmonic Distortion (THD < 3%), the UPS ensures efficient power utilization and minimal electrical interference.

The UPS supports a wide input voltage and frequency range (40–70 Hz), allowing reliable operation even in unstable power conditions. It also features a high output power factor of 1.0, enabling better load capacity and improved system efficiency.

For scalability and redundancy, the system supports parallel operation of up to 4 units, allowing higher capacity installations and improved reliability. Additional features such as static bypass and cold start functionality ensure seamless operation during power disturbances or startup conditions.

The UPS includes configurable battery support for 30–50 batteries, providing flexible backup power solutions based on system requirements. An inbuilt isolation transformer improves electrical protection and load adaptability.

With IoT compatibility, the system allows remote monitoring, diagnostics, and control, enabling intelligent power management and improved operational efficiency.

The KT Series 120–250kVA UPS is ideal for data centers, large industrial plants, telecom networks, hospitals, and commercial infrastructures requiring high-capacity and reliable three-phase power protection.
