An Uninterrupted power supply is a gadget that acts as an emergency power backup in case of power blackouts. It continues to provide power for a short while to the connected devices even after a power blackout therefore giving the user time to finalize what he or she was doing or save their. It usually forms an important part of many systems that rely on electricity for their operations therefore UPS maintenance is paramount. It has several parts which include a rectifier, batteries and an inverter. The batteries are connected to the rectifier and inverter using a parallel circuit. When the power is on the battery is usually charging and in case of a blackout the dc power from the battery is converted to ac and then supplied to the connected device. Therefore any malfunction in any of those parts would make the device not work at all. That is why it should be inspected and maintained more often. This can be done using a simple schedule. First of all we start with quarterly schedule. This is done every three months and involves checking if connections are loose, if insulation has burned or any other faulty things and repairing them. Every six months the device should be checked for liquid spills from batteries and capacitors. The enclosure should also be cleaned and vacuumed and the HVAC equipment checked for any malfunctions. Annual inspection should also be conducted. This is done by doing temperature scans on the electrical connections to ensure they are not loose and do not produce heat. The battery-rundown is also monitored to determine if some of the batteries are near the end of their useful lives. Other tests are carried out every two years to check the circuit breakers, transfer switches and other maintenance bypasses. All these schedules ensure that UPS maintenance is carried out thoroughly and that the system works in the best condition.
