System Architecture and Software
The PFX2500 Series is the control and measurement core of a configurable KIKUSUI battery charge/discharge system.
Each PFX2512 or PFX2532 provides one charge/discharge control channel. Charging power is supplied by a compatible external KIKUSUI DC power supply, while discharge energy is handled by a compatible KIKUSUI electronic load. The selected source, load, cabling, and test conditions determine the usable system power and operating range.BPChecker3000
