What this product is
What this product is
Smartpack S (242100.400) is an ultra-compact, hot-pluggable 1U form-factor system controller built around an industrial micro-controller. It acts as the operational nerve center for DC power shelves, integrating a dual-wire CAN-bus system interface, a local high-visibility OLED interface, and an Ethernet networking subsystem that enables granular management of rectifiers, batteries, and distribution alarms.
What problem it solves
Eliminates physical space limitations in shallow 1U/2U indoor and outdoor cabinets; resolves cybersecurity vulnerabilities of legacy systems via modern SNMPv3 and encrypted interfaces; mitigates premature battery failure caused by improper equalization, uncompensated floating, or thermal runaway; significantly reduces on-site OPEX by offering remote diagnostics and configuration.
Who and where it is for
4G/5G mobile base station power distribution, FTTx broadband outdoor enclosures, railway signaling stations, edge-computing micro data facilities, and industrial utility 24V/48V standby backup installations.
Core advantages
- High-contrast local OLED display with intuitive keys allows comprehensive local setup without requiring a service PC
- Native 10/100M Ethernet with full support for SNMPv3, secure HTTPS Web GUI, and NTP automatic time synchronization
- State-of-the-art battery analytics including battery symmetry testing, boost charging, and dynamic temperature-compensated float control
- Ruggedized telecom hardware platform rated for -40°C to +65°C operation with 18V-60V DC adaptive auxiliary power
