The APC SMX1500RM2U Smart-UPS protects connected electronics from surges, lightning, spikes, and other power disturbances and prolongs battery life. 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. This device has interactive power protection and is ideal for core business servers and mid-range network gear.
