SLB-24/48-200 SLB-Series DC Load Bank
Overview
The SLB-24/48-200 SLB-Series DC Load Bank from Eagle Eye Power Solutions is purpose-built for high-accuracy discharge testing of 24V and 48V stationary battery systems, providing fully programmable constant-current loads up to 200 amps. Engineered for mission-critical environments—including utilities, telecom infrastructure, industrial operations, and data centers—it delivers precise, repeatable capacity testing to validate battery performance with confidence.
Advanced safety features, including integrated protection circuits and automatic shutdown functionality, help safeguard both personnel and equipment during testing. Optional DAC packages enable detailed per-cell voltage monitoring, while wireless communication and seamless integration with DataView software provide real-time visibility, streamlined data acquisition, and comprehensive reporting capabilities.
For expanded testing requirements, the SLB-24/48-200 can be easily paralleled with other SLB-Series load banks to increase total discharge current. Its assistant discharge mode also allows it to operate in conjunction with existing non-SLB load banks, offering a flexible and cost-effective solution for upgrading battery testing programs without the need to replace legacy systems.
