Avtron A10929 Converter Board

The Avtron A10929 Converter Board, Model K660C, is a genuine replacement module designed for Westinghouse drive systems, intended to replace aging converter boards within the drive’s control electronics and to maintain compatibility with the original Westinghouse architecture, mounting in the same chassis footprint and wiring harness as the original part. In distributor listings, the part is clearly identified by the Avtron designation A10929 and the K660C model code, and it is specifically associated with Westinghouse drives that reference 1861A19 and TG, providing a precise, application-specific match for field service and long-term reliability. The board appears in multiple refurbish and parts catalogs as a dedicated converter board for Westinghouse drives, reinforcing its status as a legitimate, factory-sourced replacement rather than a generic aftermarket alternative, with compatibility notes that engineers rely on during retrofits. For maintenance teams and technicians working with legacy Westinghouse installations, sourcing the A10929 with K660C ensures a closer form-factor, connector layout, and signal compatibility to minimize downtime and preserve the drive’s original control characteristics, calibration, and performance envelope.
