SLB-48-600 SLB-Series DC Load Bank
Overview
The SLB-48-600 SLB-Series DC Load Bank from Eagle Eye Power Solutions is designed for demanding discharge testing of 48V stationary battery systems, delivering programmable constant-current loads up to 600 amps. Ideal for utility substations, telecom networks, industrial facilities, and data centers, it provides a reliable and defensible method for verifying true battery capacity—the definitive measure of system readiness.
The SLB-48-600 incorporates comprehensive protection features designed to enhance both operator safety and system reliability. Built-in safeguards and automatic shutdown functions help prevent unsafe operating conditions, while optional DAC packages enable per-cell voltage monitoring for deeper diagnostic insight during testing. With wireless communication and compatibility with DataView software, technicians gain real-time visibility into test progress, along with robust data logging and exportable reports for documentation and analysis.
For applications requiring greater discharge capacity, the SLB-48-600 can be connected in parallel with other SLB-Series load banks to increase total current capability. The unit also supports assistant discharge mode, allowing it to operate alongside existing non-SLB load banks. This flexibility enables organizations to expand and modernize their battery testing capabilities without the need to immediately replace legacy equipment.
