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 I.
Equipped with GPIB, RS-232C and USB interfaces as standard.
Impedance measurements can be made in the range of 10 mHz to 10 kHz as well on both primary and secondary cells.

Capable of measuring impedance in the frequency range from 10 mHz to 20 kHz.
Parallel operation by same model of PLZ-4W series enhances current capacity and power capacity.
Power capacity:
1000 W, 200 A, load input terminal: 1.5 V to 150 V (KFM2150 system 1000-01)
660 W, 132 A, load input terminal: 0 V to 150 V (KFM2150 system 660-01A)
Measuring AC current can be set from 0.1% to 10% (0.1% unit) of DC load current.
Capable of IR measurement with the current interrupt method.
Capable of varying DC load current while keeping measuring AC current setting (%).
Equipped with low voltage protection
External interface equipped as standard (RS-232C, GPIB, USB)

Capable of impedance measurement that is up to 150V of input voltage when connected to KFM2150 with the dedicated cable.
Capable of 32ch/unit input, and it is expandable to 160ch in a parallel connection.
Capable of voltage and impedance measurement of arbitrary cells in a single connection due to the function that allows the ability to change the allocated terminal of the channel.
Capable of setting OVP and UVP to each channel.
Capable of voltage monitoring with the 32 channels/sec. of the scanning speed.
Capable of an individual operation as a voltage monitoring.
