The impedance meter KFM2030 is intended to enable the impedance characteristics of a fuel cell to be measured easily through the use of the AC impedance measurement method.
Using the applicat ion sof tware that comes with it, the data acquisition is possible for the I-V characteristic, the Constant Current characteristic, and the Cole-Cole plot by using the AC impedance method. With a low-power DC load (60 W) built in it, KFM2030 supports fuel cell load testing at up to 20 V, at up to 30 A.
Impedance of cells of up to 20V can be measured in the range of 10 mHz to 10 kHz. (The cell voltage can be read back as well in the 0 V-20 V range.)
Two constant current modes ranges for the load rating: 30 A and 5 A
Load current setting resolutions of 1 mA (30 A range) and 0.1 mA (5 A range) are available, with maximum power consumption of 60 W.
Undervoltage protection, overvoltage protection, overpower protection, overheat protection, overcurrent protection, and line cut detection are supported.
The backlit LCD offers enhanced visibility.
Four types of measurement value can be chosen for display freely from R, X, | Z |, θ , V, and current.
Equipped with GPIB, RS232C and USB interfaces as standard.
