KUKA 00-131-492 | 1FK7103-5AF81-1YY3-Z Robot Power Supply Module | KR C4 Platform
Engineering Background
The KUKA 00-131-492 is a factory-original power supply module engineered for the KR C4 robot controller ecosystem. It serves as the primary DC bus power conditioning unit, delivering regulated 27 V DC to the servo drive chain and safety-critical I/O subsystems. This module is cross-referenced under multiple KUKA internal part numbers — C400-216-801, 00-169-213, and 00169213 — reflecting regional procurement variants of the same validated assembly.
Product Positioning
Designed for procurement engineers and maintenance teams operating KUKA KR C4-based robotic cells in automotive, electronics, and heavy-industry environments. This unit is a direct OEM replacement, eliminating compatibility risk and re-qualification overhead associated with third-party alternatives.

- Multi-alias compatibility: Single unit resolves procurement across part numbers 00-131-492, C400-216-801, 00-169-213, and 00169213.
- Servo-matched pairing: Pre-validated for use with 1FK7103-5AF81-1YY3-Z (S17) servo motor, ensuring drive-chain coherence.
- Plug-and-play replacement: Direct mechanical and electrical fit into KR C4 cabinet — no wiring modification required.
- Reduced downtime risk: Stocked unit ships within 1–3 business days, minimizing production line stoppage.
System Architecture & Signal Flow
Within the KR C4 cabinet, the 00-131-492 power supply module receives mains AC input (typically 400 V / 480 V 3-phase) via the cabinet’s primary contactor and rectifier stage. It conditions and regulates the output to a stable 27 V DC bus, which feeds:
- KPS (KUKA Power Supply) servo drive modules
- KSP (KUKA Servo Pack) axis controllers
- Safety-rated I/O and EtherCAT communication backplane
- Teach pendant (smartPAD) power rail
The 1FK7103-5AF81-1YY3-Z servo motor (S17 designation) connects downstream of the KSP axis module, completing the motion control loop under KR C4 firmware supervision.
Sourcing & Quality Verification

- Shipment: DHL / FedEx express worldwide; EXW Xiamen or DAP available for volume orders.
- After-sales support: 12-month warranty on OEM new units; 6-month on certified refurbished.
Technical FAQ
Q: Is 00-131-492 compatible with KR C4 Compact controllers?
A: Yes. The module is dimensionally and electrically compatible with both standard KR C4 and KR C4 Compact cabinet variants.
Q: Can this unit replace C400-216-801 or 00-169-213 directly?
A: Yes. These are KUKA-internal cross-reference numbers for the same validated assembly. No hardware or software changes are required.
Q: What servo motor does this power supply pair with?
A: The 1FK7103-5AF81-1YY3-Z (Siemens SIMOTICS S, S17 frame) is the validated servo pairing for this power supply in the KR C4 drive chain.
Q: Is a firmware update required after replacement?
A: No firmware update is required for the power supply module itself. KR C4 controller firmware manages the drive chain automatically upon power-on self-test (POST).
Q: Do you provide export documentation for customs clearance?
A: Yes. Commercial invoice, packing list, and HS code declaration (HS 8537.10) are provided with every international shipment.
