PFX2512
System Configuration
The following figure shows a basic configuration example of a charge / discharge system that uses
the PFX2512. The system consists of a PFX2512, Kikusui’s DC power supplies and electronic loads,
and peripheral subsystems.
The PFX2512 functional block is mainly made up of a DUT voltage / current / temperature
measurement section, a digital constant current / constant voltage control section, a power supply
/ electronic load I / F section, a host communication control section, and a load switch.
The PFX2512 has an interface that directly connects to Kikusui’s power supplies and electronic
loads. The system is designed to allow full-scale charge / discharge testing with easy initial
configuration without extra equipment or external circuits.
The connection status of DC power supplies, electronic loads, and DUT (battery) is constantly
monitored. If a problem is detected in any of the devices, the charge / discharge test is safely
aborted.
The PFX2512 is controlled from a PC through the LAN interface.
Application software BPChecker3000 is used to configure and control charge / discharge test
conditions. For details on the application software, see the corresponding help file.
