The Kikusui PBZ SR series is an integrated high-power four-quadrant bipolar power system built on standard PBZ units assembled inside a Smart Rack cabinet. Master-slave parallel synchronization, current sharing and interlock protection are factory pre-calibrated, eliminating manual user wiring for high-current bidirectional power emulation

Three cabinet configurations are available: 3-unit, 4-unit and 5-unit parallel stacks, with four voltage grades ±20 V / ±40 V / ±60 V / ±80 V. Max system output reaches ±100 A with peak total power up to 2010 W. Adopting hybrid switching pre-regulation + linear output topology, it delivers 100 kHz CV bandwidth and full four-quadrant operation, acting as both DC source and electronic load with seamless zero-crossing ±V/±I output.
