FAQs

 Why do I need a UPS?

Computing and other electrical equipment is sensitive to irregularities in mains power supply. A power cut can result in a severe and significant loss of data, costing millions of pounds each year. In addition, dips or surges in power can reduce the life of computer hardware – a UPS can prevent this. Commercial and industrial organisations rely on an interruptible power supply for business continuity.


 How long does a UPS run when the AC mains fails?

Usually if the UPS is at full capacity the battery will run for approx 10 minutes. However longer run times are possible but this depends on the number of batteries that are installed within the UPS and the load that it supports. See the product specification tables for examples.


 What is the difference between Line Interactive and On-Line UPS systems?

A line interactive UPS corrects power inequalities within a suppression range as well as providing temporary battery back-up if power fails, whereas an On-line UPS conditions and regenerates the power supply at all times, correcting all irregularities, including enabling longer-term battery power if the supply fails. On-line uninterruptible power supplies are very reliable and are amongst the most advanced UPS systems available.

 How can I monitor the power supply or UPS status when it is connected to the load?

The UPSilon 2000 software that is supplied with every UPS allows you to monitor the UPS load status and it monitors the battery on a regular or constant basis.


 What sort of alarm would be activated in the event of a power failure?

If a power event occurs, the UPS will notify you with audible alarms and can send a message notification if the software is installed.


 Can the UPS perform a safe shut down of the connected equipment in the event of a power failure?

It is possible to perform an automated shutdown of most major operating systems using the UPSilon 2000 software supplied with every Zigor UPS.


 What is the difference between single phase and three phase electricity?

In a general sense, the AC power supply in a home is called single phase because both voltage waveforms are in phase, or in step, with each other. Single-phase electric power refers to the distribution of AC electric power using a system in which all the voltages of the supply vary in unison. Single-phase distribution is used when loads are mostly lighting and heating, with few large electric motors.

Three phase electricity is delivered all around Europe. Between any phase and neutral we get roughly 230 volts. Between any two phases we get about 415 volts. Large office premises and industrial sites usually have all three phases supplied in order to run heavy equipment. Zigor provides both single phase and three phase UPS systems.
