ABB DSQC345C 3HAB8101-3 Drive Rectifier Unit – IRC5 Robot Controller Power Supply
When a drive rectifier unit fails inside an ABB IRC5 robot controller, the entire production line comes to a halt. The robot loses its power conversion backbone — AC mains voltage can no longer be transformed into the stable DC bus voltage that servo drives depend on. Without a functioning rectifier, every axis goes dead, every programmed motion stops, and every minute of downtime translates directly into lost output, missed delivery windows, and escalating maintenance costs. In high-throughput automotive, electronics, and heavy-industry environments, this single component is the gatekeeper between your power grid and your robot’s motion system.
The ABB DSQC345C, part number 3HAB8101-3, is the factory-specified Drive Rectifier Unit for ABB IRC5 single-cabinet and dual-cabinet robot controllers. Within the IRC5 platform — ABB’s most widely deployed industrial robot controller family — the DSQC345C occupies a critical position in the drive module stack, converting three-phase AC input into a regulated DC bus that feeds the axis computer and drive units for all six robot axes. Its robust design, tight voltage regulation, and compatibility with ABB’s SafeMove and FlexPendant ecosystem make it the preferred replacement part for maintenance engineers worldwide.

Frequently Asked Questions
Q: What is the difference between DSQC345C and DSQC345?
A: The “C” suffix denotes a hardware revision with updated component specifications. DSQC345C (3HAB8101-3) is the current production revision and is backward-compatible with earlier IRC5 controller configurations that used DSQC345 or DSQC345B. Always verify your controller’s drive module revision before ordering.
Q: Is this part compatible with IRC5 Compact controllers?
A: The DSQC345C is designed for the standard IRC5 single-cabinet and dual-cabinet drive module. IRC5 Compact uses a different power architecture. Please contact us with your controller type and serial number for confirmation.
Q: Can I get a datasheet or test report for this unit?
A: Yes. We provide available documentation upon request after inquiry submission. Contact [email protected] with your order reference.
Q: What is the lead time for the ABB DSQC345C?
A: Lead time depends on current stock status. In-stock units typically ship within 2–5 business days internationally. Contact us for real-time availability.
Q: Do you accept returns or offer a warranty?
A: Yes. Konmask.com offers a standard warranty on all parts. Terms vary by condition (new vs. refurbished). Please review our warranty policy or contact our team for details specific to your order.
