N+X Parallel Redundancy (Supports up to 4 Units)

Allows up to 4 units to be configured in parallel for increased capacity or redundancy. N+X configuration ensures seamless failover protection, maintaining power continuity even if one unit fails.

High Output Capacity with 0.9 Power Factor

Delivers 18000W of usable power at a 0.9 output power factor, enabling full support for modern, high-efficiency servers and power-hungry equipment.

Inbuilt Batteries and Extended Runtime Support

Equipped with inbuilt batteries for standard backup requirements, while supporting optional external battery packs for extended runtime in critical environments.

Zero Transfer Time (0ms)

Ensures uninterrupted power delivery with zero transfer time, ideal for sensitive electronics and mission-critical systems.

Wide Input Voltage and Frequency Range

Supports a wide input range of 208V – 478V AC and frequency range from 40Hz to 70Hz, ensuring stable operation even under poor power conditions or generator supply.

PFC Technology and Low Harmonic Distortion

Features power factor correction (PFC) technology with input current harmonic distortion under 3%, reducing impact on upstream power infrastructure and improving overall energy efficiency.

ECO Mode Support

Reduces power consumption and heat output during stable grid conditions by enabling ECO mode, which increases operational efficiency.

Fully Digital Charging, Rectifier, and Inverter Control

Digital control over all internal power stages ensures better precision, faster response times, and improved system reliability.

DC Start Functionality

Enables the UPS to power on directly from batteries in the absence of utility power—ideal for emergency startup and disaster recovery.
