Where This Product Is Used
The KUKA KRC4-00-183-926A1-X3 is the dedicated 27V / 40A power module for the KUKA KRC4 robot controller cabinet. It is specified by automation engineers and maintenance teams across the following industries and applications:
- Automotive Body-in-White (BIW) Lines — Powers KRC4-controlled KUKA KR QUANTEC and KR AGILUS robots performing spot welding, seam sealing, and panel handling on high-throughput assembly lines.
- Automotive Paint Shops — Supplies stable 27 V DC bus voltage to KRC4 cabinets driving painting robots in explosion-risk zones where voltage stability is safety-critical.
- General Industrial Assembly — Used in machine-tending, palletizing, and pick-and-place cells where KRC4 controllers manage multi-axis coordinated motion.
- Aerospace & Defense MRO — Installed in precision drilling and riveting robot cells requiring uninterrupted 27 V logic power to avoid mid-cycle faults.
- Electronics & Semiconductor Manufacturing — Supports cleanroom-compatible KRC4 variants in wafer-handling and PCB assembly automation.
- Food & Beverage Packaging — Keeps KRC4 cabinets operational in high-humidity, washdown-adjacent environments where power module reliability directly impacts OEE.

Application-Specific FAQ
Q: Is KRC4-00-183-926A1-X3 compatible with the KRC4 compact controller?
A: Yes. The 27 V / 40 A power module is shared across the KRC4 standard, KRC4 compact, and KRC4 smallsize cabinet variants. Verify your cabinet’s power section label before ordering.
Q: Can this module be used as a direct drop-in replacement without reconfiguring KUKA WorkVisual?
A: Yes. This is a hardware-only power supply replacement. No WorkVisual project changes or controller re-commissioning are required.
Q: What causes premature failure of the KRC4 power module?
A: The most common causes are sustained input voltage sags below 380 V AC, blocked cabinet ventilation leading to thermal stress, and inrush current from frequent E-stop cycling. Ensure your cabinet fan assembly is functional before installing a replacement module.
Q: Do you provide a warranty?
A: Yes — 12 months from date of shipment against manufacturing defects. Warranty does not cover damage from incorrect installation, overvoltage events, or physical impact.
Q: Can you supply multiple units for a fleet maintenance program?
A: Yes. Contact us at [email protected] or call +0086 19859288691 to discuss volume pricing and consignment stock arrangements.
