LB-125-600-CC LB-Series Constant Current DC Load Tester
Overview
The Eagle Eye Power Solutions LB-125-600-CC LB-Series Constant Current DC Load Tester provides programmable constant current discharge testing for 125V DC battery systems up to 600 amps. Designed for utility substations, telecommunications facilities, UPS systems, industrial DC plants, and other stationary power applications, this model delivers dependable battery capacity verification and performance validation.
The LB-125-600-CC features intelligent constant current technology that maintains the programmed discharge level throughout the test without manual adjustment. Its backlit LED display provides clear visibility of voltage, current, and elapsed test time, ensuring operators have accurate, real-time feedback.
Four programmable discharge auto-stop conditions — including test time, end voltage, exceeded capacity, and cell voltage (when applicable) — enhance test control and safety. Built-in protections automatically stop the discharge in the event of overheating, abnormal battery disconnection, or improper polarity detection.
