A series of technologically advanced uninterruptible power supply systems (UPS) on-line (VFI), constructed according to a double-conversion topology, where the active output power reaches the apparent power value. POWERLINE RT PRO series power supplies protect sensitive devices and systems from major power grid problems such as power outages, voltage surges and sags, surges and harmonic distortions. The main purpose of POWERLINE RT PRO series EVER power supplies is: network devices, servers, workplaces, as well as other electrical, electronic and IT devices. Direct operation with true dual processing, sine wave output voltage (with premium VFI SS-111 parameters) Active output power equal to apparent power (PF=1) ECO mode to reduce losses Rack/Tower housing Backup timing prediction - timing UPS autonomy in real time - via PowerSoft software and on the screen Wide input voltage window (range) Possibility to control the output sockets (1 section) Cold start Remote emergency shutdown function EPO (Emergency Power Off) ROO function (Remote ON) / OFF) - possibility remotely turn on/off the power supply Possibility to extend the backup time by connecting external battery modules (up to 4 pcs) Automatic detection of the number of connected battery modules Free PowerSoft monitoring and control software (download)
