This 2000VA On-Line UPS in tower format is designed to provide high-level double-conversion electrical protection for IT infrastructures, critical systems and professional applications that require a continuous, stable and fully isolated power supply. Its compact tower format makes it ideal for environments where rack cabinets are not used.
Thanks to on-line double conversion technology with advanced digital control, this 2000VA on-line UPS eliminates micro interruptions, voltage spikes, fluctuations, harmonic distortion and any electrical disturbances from the mains. The pure sine wave output ensures full compatibility with servers, sensitive electronics and critical loads.
The system features a 1.0 output power factor, allowing full utilisation of the available active power, and achieves an efficiency of up to 95%, helping to reduce energy consumption and operating costs. Its wide input voltage range minimises battery usage and extends battery service life.
This on-line UPS in tower format integrates an intelligent charger with support for charging current up to 12A in extended runtime versions. It also includes ECO mode, cold start, compatibility with generators and intelligent fan speed control.
The 2000VA On-Line Tower UPS is equipped with a blue multifunction LCD display, providing clear information on system status, operating modes, voltage, frequency, load level, battery status, internal temperature and remaining backup time. It includes RS232 and USB communication interfaces for easy monitoring and management.
Due to its performance and reliability, this 2000VA on-line UPS in tower format is ideal for servers, IT infrastructures, professional workstations, communication equipment and mission-critical systems requiring maximum electrical stability and service continuity.
