Maintenance and service

We have the facilities and extensive experience to repair and maintain virtually any UPS brands including APC, Eaton, Meissner, Tescom, Tower, Mecer, Liebert, Delta and MGE to name just a few. Once technicians have been carefully selected and are thoroughly trained so that they  are equipped with the necessary tools to problem solve. Following this route, technicians are able to repair units down to component level. They have many circuit diagrams at their disposal and as a result Uptech is proud of a high repair success rate.  Our expertise include repair, service and battery replacement on 3-phase and single phase UPS’s which are completed onsite. Over the years we have established relationships with UPS companies abroad for technical support and spares. We also have access to many hard-to-find discrete components which we source from various suppliers globally. Maintenance contracts, which include regular services (see service offer) of a UPS at varying time intervals according to the client’s requirements, are also provided. 

It is important to service a UPS regularly, especially units that power critical loads in data centers. System damage and data loss can be prevented by servicing the UPS regularly. Since networks rely on the correct functionality of a UPS, the importance of maintaining it should not be under estimated. Often a user will discover that a UPS needs attention only once a power failure has occurred and this inevitably results in downtime. Technicians at Uptech have often arrived at sites to discover a UPS running in bypass due to a fault or overload, without anybody at the organisation concerned having realized it. When servicing a UPS our technicians will advise system operators on how to check that the UPS is running correctly. The following is a description of some of the procedures followed by technicians when servicing a UPS.
