YK012411B
Buying YK012411B from Flexa Systems
Buy the Johnson Controls YK012411B VFD, in stock brand new and refurbished, or send yours to Flexa Systems for repair. This drive is rated 480 V, 12 A and 7.5 HP, so it suits a 480 V supply feeding a motor at or below that horsepower and full-load current. In building and process systems, drives of this size commonly run fan or pump motors, where a dead drive halts airflow or circulation until a replacement is wired in. Each YK012411B is tested before it ships and is covered by a 2-year warranty, and the refurbished unit typically costs 30-60% less than new.
Repair option: send in your faulty unit for component-level repair — $550.00 with free diagnostics, a 2-year warranty, and a 5–30 business day turnaround. Repair typically costs 40–70% of a new unit, saving you 30–60%. Learn more about our VFD repair service.

YK012411B FAQ
What should I match before swapping in a YK012411B?
Check the motor nameplate: it should be a 480 V motor rated 7.5 HP or less with a full-load current within the drive's 12 A rating. Confirm the incoming supply is 480 V. Record or back up the parameters from the old drive first so you can re-enter the motor data, speed limits and ramp times on the new one.
Should I buy the YK012411B refurbished or brand new?
Both conditions are in stock with identical 480 V, 12 A and 7.5 HP ratings. A refurbished drive is a cost-effective way to restore an existing fan or pump line. Brand new suits projects or specifications that call for unused equipment.
