This 1000VA On-Line UPS in tower format belongs to a new generation of double-conversion uninterruptible power supply systems, designed to deliver continuous, high-quality electrical protection for IT equipment, critical systems and professional applications. Its compact tower design makes it ideal for installations where rack cabinets are not available.
Thanks to on-line double conversion technology with full digital control, this 1000VA on-line UPS provides a power supply fully isolated from the mains, eliminating micro interruptions, voltage spikes, fluctuations, harmonic distortion and any electrical disturbances. The pure sine wave output ensures full compatibility with 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%, contributing to energy savings and reduced 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 to optimise battery performance, 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 1000VA On-Line Tower UPS is equipped with a multifunction blue LCD display, providing clear information on operating status, working modes, voltage, frequency, load level, battery status, internal temperature and remaining backup time. It includes RS232 and USB communication interfaces, enabling easy system monitoring and management.
Thanks to its performance and reliability, this 1000VA on-line UPS in tower format is ideal for servers, professional workstations, communication equipment, IT infrastructures and mission-critical systems requiring maximum electrical stability and service continuity.
