UPS Power Solutions
What is a UPS power solution?
A UPS power solution provides a source of back-up electricity in the event of a mains power failure. A UPS sits between the mains supply and ‘the load’. At its simplest, it conditions electrical current, converts it from AC to DC, and negates potentially harmful power problems including sags, surges, brownouts and fluctuations. In the case of a total mains power cut, the UPS powers the load from its back-up battery until another energy source starts up.
What are the different types of UPS?
There are three primary types of uninterruptible power supply:• Online or Double Conversion
• Line Interactive
• Offline (or Passive Standby).
An Online or Double Conversion UPS maintains voltage and frequency variations within prescribed limits so output is independent of supply fluctuation. As well as conditioning mains power to negate problems, this is the only UPS solution that provides break-free supply to the plant or datacenter during a power outage. A Line Interactive UPS uses built-in passive electronic regulation devices to stabilize and regulate voltage fluctuations. When mains supply power is present, the output frequency of the UPS tracks the input of the mains. Line Interactive and On-Line UPS use tower or ‘rackmount’ case formats and sit next to their respective loads, typically in a datacenter or computer room. An Off-Line or Passive Standby UPS is a compact device designed for desktops or wall mounting, which uses its own output to track voltage and frequency variations in the mains supply power.
What is a transformer-based UPS system?
While many UPS are transformerless, organizations reliant on larger datacenter and voice networks, industrial processes, security or hospital applications, often require transformer-based uninterruptible power supply. This gives greater robustness, albeit with slightly lower efficiency and greater heat and noise generation.
What should I look for in a UPS provider?
Choosing a UPS supplier involves much more than merely finding a contractor to install the inverters, bypasses, power conditioning and other technology between a critical load and its AC power source. When it comes to designing, installing and maintaining your power protection solution, or choosing a UPS manufacturer as a channel partner, your short-listing criteria must go deeper into their experience, capability and future potential. Here are some pointers:• Do they know their business and do they specialise in it?
• Do they know your business?
• Have they got experience in similar sectors?
• How large is their product range?
• Can they supply a full range of UPS products and accessories from stock?
• Do they support other systems or will they tie you into theirs?
• Can they grow with your business, share your aspirations and complement your company culture?
Rather than merely providing one-size-fits-all solutions, Riello UPS, brings depth and breadth of experience to any company’s power protection needs – while all the time adding value through design, installation, maintenance, warranty, extended warranty and ongoing consultancy services.
