    What is a UPS and why do I need one?

    A UPS is an Uninterruptible Power Supply or alternatively known as Uninterruptible Power Source. A UPS provides instantaneous power to a load requirement. A UPS system can be used either on its own, or in conjunction with a backup generator.

    A UPS is made up of 4 main parts, a rectifier, UPS battery(s) inverter and static switch. The rectifier steps down the voltage if required, converting the current from AC (alternating current) to DC (direct current), this is done to allow for smooth flow of current through the UPS. The rectifier can also aid with the charge of the UPS battery(s).

    The UPS battery can be charged either by the rectifier, or by an external battery charger. The battery(s) can be either built inside of the UPS system, or in standalone casing, pending the UPS autonomy and KVA specification.

    The inverter converts the DC current back to AC.

    The Static Switch, works similarly to how a ATS panel works with a generator. The static switch acts as a safeguard to the UPS and connects the load to the mains supply and can bypass the other parts of the UPS as mentioned above should there be a fault with the UPS.

    UPS Servicing & Maintenance

    It is just as important to have regular health checks and the correct servicing and maintenance on UPS Power Supply Systems. Our UPS services are designed to protect you and your business from any unnecessary down time.

    We can tailor make our UPS service packages to suit your business application, however we predominantly recommend two service packages, minor UPS Servicing and major UPS servicing.

    Our basic service packages include:

    • Battery life span test
    • Cabinet Clean
    • Firmware Upgrades
    • Thermal Imaging

    Battery impedance testing is a service we can provide in our UPS service packages, we can provide a full battery health check report and on individual cells. If batteries don’t meet the manufacturers requirements, then batteries will be replaced before down time occurs. 

    Are UPS only used for data centres?

    In short, no. A UPS can have many application types, ranging from your computer at home, to tills at your local shop, all the way to telecoms units, hospitals or as mentioned, data centres.

    Here at Constant Power Solutions we currently supply a wide array of UPS all the way from 1KVA up to 1500KVA, with plenty more available if you have a specific requirement, and if you’re not sure, we offer free site surveys so we can always attend site to measure up your requirement.
