Featuring Multiple Current Ranges in 5/25/50 Amp and 10/50/100 Amp Configs
New Model Available - The 890e is the latest member of the 890 family of versatile fuel cell test loads. The 890e is a computer controlled instrument with a multi-range programmable electronic load, fuel flow and temperature controls, and data acquisition functions in a compact rack mount or bench top unit. The 890e series loads are targeted at small to medium size (up to 100 Amp, 125 Watt) single cell or low-power stack for laboratory research. The 890e's multiple current range capability enhances its versatility and performance over a wide range of test applications and test environments.
The 890e sets the new benchmark, in value and performance, for fuel cell test loads. The 890e is fully compatible with our FuelCell® (Windows 2000/XP) software package creating a powerful tool for conducting your experiments.
The 890e is designed for use with a fuel cell or stack, custom or third-party fuel management unit, and our optional internal model 880 Frequency Response Analyzer (FRA) for full-spectrum Electrochemical Impedance Spectroscopy (EIS) and continuous High Frequency Resistance (HFR) measurement.
