Smartpack R is an autonomous 1U chassis-level supervisory controller for mission-critical DC power plants. Built with an industrial processor, tactile 3-button keypad, and backlit display on the front panel, its rear panel houses CAN bus interfaces, 10/100M Ethernet, configurable relay outputs, and analog inputs for comprehensive DC plant orchestration.
Eliminates backplane slot constraints of modular controllers, resolves cross-voltage spare-parts complexity (single unit serves 24V and 48V networks), overcomes network protocol integration barriers, and prevents catastrophic battery failures through advanced life-cycle algorithms.
Telecommunication central offices, 4G/5G mobile base stations, railway signaling and traction control power rooms, smart grid substations, and mission-critical enterprise edge data enclosures.
