The uninterruptible power supply system is designed to protect electronic equipment from surges and other power events. It features two Ubs charging ports with 2.4 amp shared output, minimizing noise and reducing power consumption. The system also provides a battery backup to prevent data loss during shutdowns. It features a line-interactive topology with an autotransformer for voltage regulation without switching to the battery. The system also offers a stepped, approximated sine wave output for cost-effective battery backup power. The system also features Usb charging ports for charging and powering Usb devices.
