Kikusui KFM2005 Fuel Cell Impedance Meter

Description

Kikusui KFM2005 Fuel Cell Impedance Meter is a measuring instrument developed for fuel cells used with small currents (5A or less). In addition to current-voltage characteristic tests, you can easily measure impedance using the AC impedance method and Cole-Cole plot. It is also possible to calculate the circuit constants of the approximate equivalent circuit of a fuel cell from the measured data of the Cole-Cole plot. Furthermore, it has a built-in DC electronic load device (60W) compatible with 0V, which supports testing of fuel cells up to 20V and 5A.

Application software Kikusui KFM2005 included as a standard accessory 

Equipped with GPIB, RS-232C and USB interfaces as standard

The impedance measurement using AC
impedance method
l Frequency range: 10mHz to 10kHz
l Frequency resolution: 14 points/decade
l Impedance measurement range: 100mΩ, 300mΩ, 1Ω, 3Ω
l Measurement alternated current range: 16.5 mA range, 50 mA range
The selected range of measurement AC current can be set for
10% to 100% of the rated value in 0.1% step. The impedance
measurement can be measured by the dummy rated voltage which
varies automatically for the measured AC current to become at
5mVpp of the detected terminal voltage of the DUT.

The built-in DC load (60W) is capable
to operate from 0 V
l Not only for stack cell, it can also apply for single cell testing
l Operating mode: Constant Current
l Current range: 0.5A range, 5A range
l Current setting resolution: 0.01mA(0.5A range), 0.1mA(5A range)
l Input voltage range: 0V 〜 20V
l Maximum input power: 60W

Useful application software is included
It is possible to start immediate testing for the measurement of Cole-
Cole Plot, I-V characteristics, and Constant Current characteristics
simply by entering the parameters and acquiring the test data easily.

Various controls by external
control functions
The Kikusui KFM2005 allows you to control not only from the panel or
through the communication interface but also using external signals
from the control terminal .
l Controlling the load current using an external voltage
0.5 A range : 0 V to 10 V at 0 A to 0.5 A
5 A range : 0 V to 10 V at 0 A to 5 A
l Turning the load current on/off
l Swithching the load current range
l Voltage monitor output : outputs 10 V at 20 V of the sensing input
voltage
l Current monitor output : outputs 10 V at 5 A of the load current
l Alarm output : occurred when abnormal state is detected such
as OHP, Over Load, OCP.
l Status output of the LOAD ON/OFF
(output of the ON/OFF status of the load device)

Various protection functions
The protection function of UVP / OVP / OPP / OHP / OCP / OPEN
are equipped as standard
For the secondary or the primary battery testing
The impedance can be measured in the range of 10 mHz to 10 kHz.
