VI933T Series 100-200kVA Tower UPS

The VI933T Series Tower UPS is a high-performance, industrial-grade power protection system designed to ensure uninterrupted operation for mission-critical applications. Built with advanced digital control technology and a robust architecture, it delivers clean, stable, and reliable power for large-scale commercial and industrial environments.
Engineered with online double conversion technology, the VI933T series provides complete isolation from power disturbances such as outages, voltage fluctuations, surges, harmonics, and frequency variations. With a unity output power factor (kVA = kW) and system efficiency of up to 96.8%, it maximizes usable power while minimizing energy loss.
This UPS features a fully digital DSP control system combined with a 7-inch touch LCD, enabling precise power management, real-time monitoring, and enhanced operational control. Its intelligent fan design optimizes cooling performance by adjusting speed based on load conditions, reducing both energy consumption and noise.
Designed for flexibility and scalability, the VI933T supports parallel operation for redundancy and capacity expansion, making it ideal for growing infrastructures. It also includes advanced battery management, ensuring longer battery life through accurate charging control, self-diagnostics, and intelligent monitoring.
With a wide input voltage range, low harmonic distortion (THDi < 3%), and high input power factor (>0.99), the system ensures superior power quality while reducing strain on upstream electrical infrastructure.
Built to perform in demanding environments, the VI933T operates reliably in temperatures from 0°C to 40°C and humidity levels up to 95% (non-condensing). Its rugged design, combined with zero transfer time and dynamic load response, guarantees continuous power delivery for critical loads.
