Constant Current DC Load Banks with Cell Monitoring

Eagle Eye’s LB-Series Constant Current DC Load Banks are designed for discharge testing, 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 5 – 600V / 0 – 2000A. The intelligent technology allows a constant current discharge without the need for any adjustments during the test. The LB-Series is essential in a variety of industries including utilities, telecommunications, UPS, motive power / forklifts, transportation, CATV, and many more.

Benefits

  • LED display for voltage, current, & test time
  • Three test conditions for discharge auto-stop: Test Time, End Voltage, Exceeded Capacity, and Cell Voltage
  • Unit will alarm and end discharge in the event of overheating, abnormal disconnection of battery, improper polarity detected
  • Automatically runs fans after the test has concluded for maximum heat protection
  • Previously used parameters saved after powering off the machine
  • Optional models include programmable load steps, cell monitoring, software package, and 5” LCD with touchpad
  • Optional Software includes reporting to Microsoft Excel, Word, data graphs, remote load control, and more

FAQs

What are some common applications areas for this product?

Common applications include but are not limited to:

  • DC Generator Systems
  • DC Battery Systems
  • UPS Testing
  • Rectifiers
  • Power Supply
  • Power Converter Units
  • Standby Generators
  • Diesel and Gas Turbines
  • Micro-turbines
  • Wind Generators
  • Solar Arrays
  • Electrical Distribution Systems
  • Circuit Breakers
  • Other Electrical and DC Power Supply Testing

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.
