The UPS has a multifunction LCD display which offers real-time information, including input and output voltage levels, load and battery levels, battery runtime, overload warning, and a silent mode. With the network ports on the UPS, it prevents network devices from being subjected to sudden power surges caused by lightning, thereby avoiding potential system damage. As for battery maintenance, the UPS allows battery hot-swapping, which enables users to perform normal battery maintenance without significant interruption.
