SLB-125-200 SLB-Series DC Load Tester
Overview
The Eagle Eye Power Solutions SLB-125-200 SLB-Series DC Load Tester is engineered for reliable capacity and performance testing of 125V battery systems with discharge capability up to 200 amps. Designed for utility substations, telecom facilities, data centers, and industrial DC applications, this model provides programmable constant-current discharge testing — the only verifiable method to confirm true battery capacity.
With built-in safety features, auto-shutdown protections, and optional per-cell monitoring via DAC packages, the SLB-125-200 increases both technician safety and system reliability. The unit supports wireless remote monitoring and integrates with DataView software for live test viewing, data recording, and Excel-ready report exporting.
For expanded testing capability, the SLB-125-200 can be paralleled with another SLB-Series unit to increase discharge current capacity. It can also operate in assistant discharge mode alongside existing non-SLB load banks, allowing users to modernize testing systems without fully replacing legacy equipment.

FAQs
Why is discharge testing necessary for battery systems?
Discharge testing is the only verifiable method to confirm true battery capacity. It ensures the battery system can support required loads during an outage and identifies weak cells before failure occurs.
Is the SLB-125-200 suitable for NERC compliance testing?
Yes. The SLB-125-200 provides programmable constant-current discharge testing and exportable reporting through DataView software, supporting documentation requirements for NERC-related maintenance programs.
Can I increase discharge current beyond 200 amps?
Yes. The SLB-125-200 can be paralleled with another SLB-Series unit to increase total discharge current capacity while maintaining programmable control and monitoring.
Does the SLB-125-200 support individual cell monitoring?
Yes. With the optional DAC package, the SLB-125-200 can provide real-time voltage monitoring for individual cells including 1.2V, 2V, 6V, and 12V configurations. Custom DAC options are also available.
Can this unit be used with existing load banks?
Yes. The Assistant Discharge feature allows the SLB-125-200 to operate alongside existing non-SLB load banks, increasing current capacity and adding monitoring capability without replacing legacy equipment.
What battery systems is the SLB-125-200 designed for?
The SLB-125-200 is designed for 125V DC battery systems commonly found in utility substations, telecom facilities, data centers, and industrial power applications.
