Variable-frequency drive parts

What we stock

A variable-frequency drive runs hot and runs all day, so it wears out in the same places a UPS does. The cooling fans slow down, the capacitors in the DC bus age with heat, and the control boards are the parts most likely to be discontinued before the drive itself is.

Drives are matched by model and rating, not by size. A fan or board that fits one drive family often will not fit the next, so we quote from the part number on the label and tell you the condition of every part. If a part is tied to a firmware version or a parameter backup, ask us before you order.
