Zadok

Sending a defective VFD (or any converter) back to its factory can be a daunting prospect with no known ceiling on turnaround time or cost. Our PES department is right here in Houston to provide straight answers, reliable estimates of cost and time to end users in the Gulf States.

AC converter and VFD failures are inevitable.  The power electronics service (PES) group of 741 solutions is a local, fast, and economical provider of repair and testing services for a huge array of drives which employ different technologies.

Repair services are offered for these types of drives

If you have a converter type that does not appear on this list, feel free to contact us; we may still be able to service it.
