The APC SUA1500R2X93 Smart-UPS simplifies your installation & maintenance while providing a safe system shutdown and advanced UPS management. The UPS periodically runs self-tests to ensure that you have early notice of when a battery needs to be replaced. The power management of the UPS can be managed through the network to provide ease of use even in remote locations. The audible alarm actively lets you know if the battery is low or if there is an overload condition.
