Many faults or failures with small UPS (Uninterruptible Power Supply) can be economically repaired without the need to replace them. At UPS Systems, we can offer you a UPS repair service and workshop inspection which will fully inspect, analyse and identify the causes of faults or failures with your existing UPS. All UPS (3kVA) can be accepted for this service. For details on our service and maintenance of larger UPS please contact us. We will then provide a comprehensive and detailed report on the unit together with recommendations on and costs for repair if economically viable. If repair is not economically viable we will also provide our recommendations and pricing on a replacement unit

A successful maintenance plan takes into account the age and actual wear of a UPS to determine where a specific device is relative to its expected life cycle. It also helps budget for major replacement items like batteries or capacitors. Proactively replacing your batteries will help to keep your power system running within specifications and minimize the risk of downtime to your business operations. Emerson offers complete battery and capacitor replacement solutions including both expert installation of new cells and proper recycling of spent batteries and capacitors.


Load bank testing places a resistive load onto the output of the UPS whose technical performance can then be tested and verified. Mains failures can be simulated and the UPS put into standby, on-line and Eco mode and the maintenance bypasses switched (both internal and external).
Load bank testing can also be used to verify the battery runtime capacity and recharge times. Batteries are connected into battery strings, which may be paralleled together to give a UPS system its overall battery capacity. Using a load bank to test the battery provides several benefits. Firstly the critical connected loads do not have to be used to test the battery, where a sudden failure could lead to a load crash. Secondly, the battery test on a load bank can be run for far longer and long enough to identify any failure in battery capacity. If any of the battery strings has a failing or weak battery it can take some time on discharge before the overall DC battery voltage across the strings starts to collapse. The only other way to test the battery is to inspect and test each battery block using a hand-held battery tester and then to analyse the recorded results.


Besides testing of your UPS (Uninterruptible Power Supply), it’s important that you test your batteries. They are the core of your UPS system and if there’s an unrecognised fault, it can mean your system failing when you need it most. UPS Batteries don’t last forever and it’s common practice to replace UPS battery stocks every 3-5 years when they are usually reaching the end of their natural life. It’s entirely possible, however, for a battery to fail before then as a result of external factors like heat, frequency of use and amount of power discharged, which can lead to a ‘domino’ effect as related batteries try and pick up the strain.

To assist customers in resolving emergency situations for emergency power systems including UPS, battery systems and inverters, we offer 24/7 on-site service within specified service areas. In the event of a power failure, experienced support professionals will respond with the expertise and proper equipment to troubleshoot the problem and get you back online quickly and safely.
