SLB-24/48-600 SLB-Series DC Load Bank
Overview
The SLB-24/48-600 SLB-Series DC Load Bank from Eagle Eye Power Solutions is built to handle rigorous discharge testing of 24V and 48V stationary battery systems, delivering fully programmable constant-current loads up to 600 amps. Designed for use across utilities, telecom infrastructure, industrial operations, and data centers, it provides a precise and repeatable method for confirming true battery capacity and overall system reliability.
Engineered with comprehensive safety features, the unit includes built-in protection circuits and automatic shutdown functionality to help safeguard personnel and equipment. Optional DAC packages allow for detailed per-cell voltage monitoring, while wireless connectivity and integration with DataView software provide real-time test visibility, efficient data collection, and streamlined reporting.
To support higher discharge requirements, the SLB-24/48-600 can be operated in parallel with other SLB-Series load banks to increase total current capacity. Its assistant discharge mode also enables compatibility with existing non-SLB load banks, offering a flexible and cost-effective solution for expanding and upgrading battery testing capabilities without replacing legacy systems.
