890e Fuel Cell Test Loads

Popis

The model 890e is the latest member of the 890 family of versatile fuel cell test loads. These computer-controlled instruments consist of a multi-range pro890grammable electronic load, fuel flow and temperature controls, and data acquisition functions in a compact rack-mount or bench-top unit. Add the 880 Frequency response analyser (FRA) option for integrated High Frequency Resistance (HFR) and full range Electrochemical Impedance Spectroscopy (EIS) measurement. 

Featuring Multiple Current Ranges in 5/25/50A, 10/50/100A, 12/62/125A or 25/125/250A Configurations (at 125W or 500W)

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 250A, 500W) 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.

New Model Available: 890e 50/250/500A 1,000W

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.
