The 57C493 is a Reliance Electric Powered Supply. This power supply may have also been sold under the Asea Brown Boveri and/or Baldor Reliance product lines depending on what years it was actually in production. None of these companies still maintain the 57C493 and it may be a little hard to track down. AX Control does make every effort to keep it in stock as either a refurbished or new surplus part.
