Eaton UPS Repair? Obsolete? No Problem!


Recently, a customer inquired with LyraTronix about having their 11kVa Eaton 9PX UPS (Model 9PX-911KTF5) repaired. They had just replaced their aging, 4 year old batteries and one week later the UPS alarm indicated a Rectifier Fault.  This fault left their load unprotected. This $12,000 UPS system was no longer supported by the manufacturer and they did not want to buy a costly new one and lose their investment in the recently purchased batteries. LyraTronix evaluated and repaired the internal circuit board, which offered significant cost savings to the customer and provided a 12-month warranty.  The customer load was back online and they continued normal operations.  Customers frequently say their equipment is no longer supported by the manufacturer, but at LyraTronix we DO what the manufacturer will NOT! Obsolete? No Problem, we troubleshoot PCBs down to the component level. Are you in need of Eaton UPS Repair? Call LyraTronix Today 1-800-643-1412
