SLB-125/240-150 SLB-Series DC Load Bank
Overview
The Eagle Eye Power Solutions SLB-125/240-150 SLB-Series DC Load Bank is engineered for controlled discharge testing of 125V and 240V stationary battery systems with programmable constant-current loads up to 150 amps. Designed for utility substations, telecom and UPS facilities, industrial DC plants, and critical power applications, this dual-voltage model provides a reliable method to verify true battery capacity — the only proven way to confirm system readiness.
The SLB-125/240-150 supports safe, repeatable testing through built-in discharge auto-shutdown features that can stop the test based on time duration, total string voltage, capacity, or individual cell voltage (when equipped with a DAC monitoring package). Wireless communication enables remote test monitoring, while DataView software provides live viewing, data recording, and report exports to Microsoft Excel.
For higher discharge current requirements, this model can be paralleled with another SLB-Series unit. It can also operate in assistant discharge mode alongside existing non-SLB load banks to modernize legacy testing setups without full replacement.

FAQs
What battery systems is the SLB-125/240-150 designed for?
This model is designed for stationary battery systems operating at 125V or 240V DC, commonly found in utility substations, telecom facilities, UPS systems, and industrial DC applications.
Why is discharge testing necessary?
Discharge testing is the only verifiable method to confirm true battery capacity. It helps ensure the battery system can support required loads during an outage and identifies weak cells before failure occurs.
Can I increase discharge current beyond 150A?
Yes. The SLB-125/240-150 can be paralleled with other SLB-Series units to increase total discharge current capacity for higher-demand testing applications.
Does the SLB-125/240-150 support individual cell voltage monitoring?
Yes. With an optional DAC package, the unit can provide real-time per-cell voltage monitoring for common cell voltages, with custom configurations available upon request.
Can I monitor a test remotely?
Yes. Wireless communication allows remote monitoring of live discharge tests, improving safety and visibility while testing is in progress.
Can the SLB-125/240-150 work with an existing load bank?
Yes. The Assistant Discharge feature enables compatibility with existing non-SLB load banks, allowing you to add monitoring and control capability without replacing legacy equipment.
