Don’t pay for what you don’t use. To maximize cost-effectiveness, the design of AMREL’S Frequency Response Analyzer is dedicated exclusively to impedance testing. Using multi-frequency AC Impedance Analysis (EIS), you can now characterize fuel cell performance, evaluate internal losses, and optimize output efficiency at a fraction of the price of other FRAs.
By buying your FRA and all your programmable power products from AMREL, you’ll minimize your supply chain, streamline your technical support and increase compatibility of your testing components. Best of all, you’ll get the same reliability and quality that you have come to expect from the eLoad line of programmable dc electronic loads, and the ePower line of programmable dc power supplies.
