Linear-interactive uninterruptible power supply (UPS) sources by SNR are designed to protect personal computers, workstations, and servers equipped with switching power supplies. Thanks to the built-in battery, the UPS can continue to operate even during a complete power outage, allowing the user to save data and properly shut down the operating system. SNR-UPS-LIRM uninterruptible power supply sources have a built-in autotransformer. The autotransformer regulates the output voltage when the network voltage changes - when the network voltage is excessively high, the autotransformer lowers the output voltage to an acceptable level, and when it is excessively low, it raises it. The autotransformer ensures the desired level of output voltage during fluctuations in the network voltage from the nominal. A wide range of allowable network voltages reduces the number of cases where the UPS switches to batteries and significantly extends the battery life.
The compact size and rackmount design allow the SNR-UPS-LIRM UPS to be installed in 400mm deep wall cabinets.
