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.
