Product Brief:

KPS‑600 is the core main servo power supply unit inside KUKA KRC2 and KRC2‑ED05 robot cabinet. It converts three‑phase mains AC into high‑voltage DC‑bus power to feed all KSD1 series servo drive modules. Integrated pre‑charge circuit limits inrush current during system power‑on; brake chopper absorbs regenerative energy generated by robot deceleration movement to prevent DC‑bus overvoltage risk. Built‑in main contactor and discharge circuit implement safe power‑on and safe power‑off sequence for maintenance operation. It communicates with DSE‑IBS safety board and MFC motion control board via Interbus drive bus,receiving system enable commands and uploading real‑time working status and fault information. Multi‑LED status indicators allow quick on‑site fault diagnosis without additional tools. The module adopts cabinet plug‑in installation structure for convenient disassembly and replacement. This is legacy EOL discontinued spare component,mainly used for power unit failure replacement of existing KRC2 robot systems. Please confirm part number,hardware revision and cabinet version before purchasing. Strict ESD anti‑static measures must be followed during installation and commissioning.
