PFX2512
Product Overview
The PFX2512 is a dedicated charge / discharge system controller used to measure the charge /
discharge voltage and current of batteries and the like with high accuracy in combination with
Kikusui’s DC power supplies and electronic loads to evaluate the characteristics of DUTs (power
storage devices such as rechargeable batteries). Depending on the DC power supply and electronic
load combination, large capacity, and wide rating range evaluation tests can be performed.
Features
Charge / discharge control system
●
Wide range of ratings
Wide range of ratings can be supported by selecting the appropriate combination of Kikusui’s
DC power supplies and electronic loads. Implementation cost can be suppressed by selecting
the appropriate devices for your charge / discharge test conditions.
●
Digital constant current (CC) / constant voltage (CV) control method
The adoption of the digital CC / CV control method minimizes the disparities in the constant
current (CC) / constant voltage (CV) setting accuracy and drift characteristics due to the
differences in the system component devices (DC power supplies and electronic loads). This
ensures highly accurate tests. There is absolutely no need to make adjustments after system
configuration.
● Highly accurate measurement
Highly accurate measurement circuits are built in. Battery voltage and charge / discharge
current are detected with high accuracy. (Voltage measurement: 100 μV resolution, current
measurement: 100 μA resolution, elapsed time measurement: monthly error of 30 s or less (10
ppm or less))
True electric energy and integrated capacity can be measured even for pulse currents that are
difficult to be captured.
●
Protection functions
The PFX2512 has a built-in path switch (load switch). The path switch is equipped with a high-
speed shutoff function that quickly detaches DC power supplies and electronic loads when an
error is detected.
It also detects electric potential difference that exceeds specified values in DUT cables and
voltage sensing wires, wiring errors, poor DUT (battery) connection, and so on to prevent
damage to the connected devices and DUTs (batteries).
For the system requirements, see the BPChecker3000 application software’s setup guide.
