H2 ECOnomy's Electronic Load Banks (ELB) are designed to monitor and control the voltage, current, and power of your fuel cell or another DC power source. These affordable and easy-to-use load banks come in three modifications; for handling fuel cells up to 1500 W, 500 W and 150 W. A PC interface can be added to enable full control of the load bank from a personal computer using the Automated User Control Interface (AUCI) software, as well as to record and digitally/graphically display the test data.
