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.

H2 ECOnomy’s electronic load banks allow testing fuel cells in three different load modes - Constant Current, Constant Voltage and Constant Power.

PCI personal computer interface with RS-232 protocol (through a COM port) can be added for to enable full control of the load bank from a personal computer using the National Instrument’s LabVIEW™ based Automated User Control Interface (AUCI) software, as well as to record and digitally/graphically display the test data.

The PCI also adds the Scan and Duty Cycle testing modes to the unit's capabilities. The Scan mode allows easy and automatic acquisition of data for polarization curves: the ELB applies incrementally increasing current values to the tested power source up to a limit set by the user over a specified period of time. In the Duty Cycle mode a specified load is turned on and off with a specified duty cycle time and period, which is most useful when activating a fuel cell or testing its durability. 

Safety features include:

• Designed to fully comply with safe operation requirements, protecting personnel from electric shock, fire and explosion.

• Overheating protection embedded.

• Includes a fuse to protect from surges, spikes and the like in the grid.
