LB-Series Constant Current DC Load Banks with Cell Monitoring
Model # LB-Series-CC
Eagle Eye’s LB-Series Constant Current DC Load Banks are battery discharge testers designed for battery capacity testing, acceptance testing, battery maintenance, and other testing of DC systems. The LB-Series constant current load banks are portable, economic, reliable and user-friendly. With over (100) standard models and an operating range of 1 – 600V / 0 – 2,000A, the LB-Series is used in a variety of industries including utilities, telecommunications, UPS, motive power/forklifts, transportation, CATV, and many more. The intelligent technology allows a constant current discharge without the need for any adjustments during the test.
In addition to the base CC models, (2) additional model packages that incorporate added features to suit the full range of our customer needs. These advanced models provide the standard CC features PLUS Data Management software, PER CELL monitoring, LCD screen, data storage, and programmable load steps. Refer to the catalog page in the downloads section for a list of all available models.
Eagle Eye’s Constant Current DC Load Banks are user-friendly and cost-effective for continuous DC load testing. Easily begin the test by programming the load test parameters with the keypad. The LB-Series Constant Current Load Banks have an LED display for voltage, current & test duration. Optional Data Management Software is available to monitor discharge events in real time, record data, analyze, remote start & stop tests, and create reports. Reports are exported to Microsoft Excel or Word and can be customized by the user. The LB-Series CC models will automatically adjust the current during the discharge test. Furthermore, the current output and cutoff parameters are both view-able and adjustable at any time during discharge testing. This is beneficial to customers looking to step their current loads up or down at certain intervals.
Previously used parameters are automatically saved after powering off the machine. The load banks have three settings to auto-stop the discharge: ‘Test Time’, ‘End Voltage’ & ‘Exceed Capacity’. In addition, an alarm will sound and end the discharge in the event of overheating, an abnormal disconnection of the battery, or if improper polarity is detected. The equipped cooling fans continue to run automatically after each discharge test to ensure maximum heat protection and prevent overheating.
Each LB-Series Constant Current Load Bank includes:
- LB-Series CC Load Bank
- 3m (10ft) Discharge Cables
- 110/220 AC Power Cable
- USB with Support Literature
- 1-year Standard Warranty
- Optional: Software Package
- Optional: Cell/Unit Voltage Monitoring
- Optional: Programmable Load Steps
Discharge testing is an essential practice for all critical backup battery preventative maintenance programs. Utility, UPS, Telecommunication, CATV/Broadband, Motive Power and other industries ALL utilize this practice to determine the true health of critical backup batteries. Load testing is the only form of battery testing that will determine the actual capacity of the battery string. Eagle Eye load banks are designed to make discharge testing convenient and easy for any application.
Load testing is a fixture in IEEE (450), (1188), (1106) and NERC (PRC-005-2) battery maintenance standards, and is critical for preventative maintenance across many industries. The financial risks that can occur due to plant downtime, personnel safety, and serious equipment damage are too severe to ignore load testing. Utilities have been load testing where preventative maintenance is required for NERC standard PRC-005-2. Every six calendar years it is required by PRC-005-2 to complete a capacity test of the battery bank for Vented Lead Acid (VLA) and NiCad batteries, and every three years for Valve-Regulated Lead-Acid (VRLA) batteries.
Load testing is increasingly popular in the motive power field to evaluate forklift batteries and to see how the batteries behave on a charge. Many forklift batteries go through an industry standard 6-hour discharge test. Eagle Eye's SLB-Series portable load banks make forklift battery testing easy and accessible.Visit us for information about our training courses for DC Power Systems.

Are the LB-Series constant current load banks compatible with online applications?
Yes, the constant current load bank could be used in an online application however we do not recommend this practice unless testing the performance of the charger / rectifier as discharging the batteries while connected to a load source leaves the batteries vulnerable for system failure.
What is meant by constant current?
Constant current means that the load bank will deliver a constant load set by the user from the beginning to end of a load test regardless of the drop in voltage.
What safety cutoffs do the LB-Series Constant Current load banks have?
The DC load bank will shut down based on user adjustable settings of time, string voltage, and capacity. It also has thermal protection shutdown.
Is the load bank able to discharge strings in parallel?
As long as the nominal voltage falls within the working voltage of the specific unit the load tester will be able to discharge parallel strings.
