UPS of the Element series, with built-in batteries 4x9Ah / 12V. Charge current up to 1.4 A. Power 1800W / 2000 VA The Element Series SNR Uninterruptible Power Supply protects sensitive electrical equipment from the most common power problems, including power failures, sags, surges, line noise, high voltage spikes, frequency fluctuations, and harmonic distortion. Power outages can occur at unpredictable times, and power quality can also change over time. Power problems are dangerous for IT equipment and can result in critical data corruption, loss of unsaved work sessions, and equipment failure - all of which can result in hours of downtime and costly repairs. These UPSs are ideal for protecting servers, telecommunications, networking and industrial equipment. Features: double voltage conversion technology provides complete equipment protection and sinusoidal output voltage in all operating modes, as well as zero switching time to the battery; output power factor 0.9; The UPS can work together with generators; Intelligent three-stage charging is used to extend battery life; supports ECO mode; cold start function; standard communication interfaces: one RS-232 communication port, one USB communication port, and an internal slot for installing an SNMP card or dry contacts; Outlet Outlet Segment Management that allows non-critical loads to be disconnected in battery mode to extend the runtime of critical loads; the ability to increase the battery life by using up to four additional external battery packs; for UPS models with built-in batteries, hot-swappable batteries are available; function of emergency shutdown through the port of remote emergency power-off (EPO - Emergency Power-off); all important information is displayed on the device screen: load power and battery status are displayed in dynamic images. It is very easy to monitor the operation of the UPS, when the UPS fails, the display shows an error code, and the equipment can be restored in the shortest possible time using the table of fault codes; The LCD display can change the orientation of the image in accordance with the type of installation of the case: vertically or horizontally; the height of all UPS models of the Element series is only 2U. Contents of delivery UPS user manual CD with software SNMP DL801 for UPS USB cable power cable (input and output) RS232 cable brackets, rack mount for installation in a rack of uninterruptible power supplies SNR, we offer you the universal SNR-UPS-RK slide. (Sold separately) The UPS data monitors the correspondence of the incoming phase and neutral, therefore, in the event of a discrepancy, they signal this with an audible signal once every two minutes.
