Linear-interactive uninterruptible power supplies (UPS) SNR are designed to protect personal computers, workstations, and servers equipped with switch-mode 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-LID uninterruptible power supply sources have a built-in autotransformer. The autotransformer regulates the output voltage when the network voltage changes - in case of excessive increase in the network voltage, the autotransformer lowers the output voltage to an acceptable level, and in case of excessive decrease, it raises it. The autotransformer ensures the specified level of output voltage during fluctuations in the network voltage from the nominal value. A wide range of allowable network voltages reduces the number of cases when the UPS switches to batteries and significantly extends the battery life.
The SNR-UPS-LID UPS is equipped with a “cold start” function, which allows the UPS to be forcibly turned on when there is no mains power.
