Why a UPS?

When it is produced, electric power is perfect; unfortunately its distribution network is not. In fact, it is affected by interruptions of various length, frequency variations, voltage reductions or increases due to maneuvers on the lines' switches, to lightning or to the release or input of relevant charges in nearby locations. It has been observed that a relevant percentage of electronic devices' breakdowns (in some instances even the 80% of times) is due to causes linked to the distribution network. The MTBF (Mean Time Between Failures) of a distribution network can vary from 24 to 900 hours, while that of an electronic device varies from 20.000 to 100.000 hours!

The economic risks caused by this could be very high for a company: costs related to the time needed to recover data and to replace hardware in IT systems in failure, the loss caused by lost sells or by worker's inactivity have to be taken into consideration too.

All valuable appliances need therefore the assurance of continuity to the input and the correct waveform for fit for each specific device (limits for tension, frequency and distortion's maximum and minimum levels).



THE DISTRIBUTION NETWORK CAN COMPROMISE THE QUALITY OF THE ELECTRIC POWER YOU RECEIVE:

TURN IT BACK TO PERFECTION THROUGH A UPS!



 

Main Drawbacks that can damage your electric and electronic devices:

  • Tension interruptions and micro-interruptions on the mains;
  • Quick tension alterations;
  • Frequency variations;
  • Brown outs;
  • Surges;
  • Wave form distortions;
  • Noises;
  • Transient faults;
  • Spikes caused by lightning;
  • Harmonic distortions;
  • Human errors.

 Mains disturbances are classified as follows:

 
CAUSES   EFFECTS

 

SAG (or BROWNOUT): short span drops in voltage. It is the most common input's disturbance (87% of the total). It is caused by the starting of electric devices such as engines, compressors, elevators and freight elevators.

 

 

The effect is the decrease of the power under the level necessary for a computer to function properly, causing stops in the keyboard's operation or unexpected system's crashes, with loss or damage of the data in elaboration.

 

BLACK-OUT: loss of the electric power to an area, caused by excessive request or by natural disaster.

 

Among the effects, we find the loss of the data loaded in the RAM or in the Cache and sometimes the loss of the FAT (File Allocation Table), with the consequent loss of the data stored in the drive.

 

SPIKE: fast and short significant increase in voltage, for example caused by lightning.

 

The effects are quite serious: the hardware may be significantly damaged and the data is lost.

 

SURGE: short span voltage increase, with a minimum duration of 1/10 s caused by the shutting down of electric engines that require high voltage.

 

Any tension's value that exceeds the limits, for which computers are designed, stresses abnormally certain particularly sensitive components and causes failures.

 

NOISE: also known as EMI (Electromagnetic Interference) or RFI (Radio Frequency Interference), it distorts the sinusoidal shape of the electric wave expected in the input, and it is caused by industrial illumination, switches, generators, broadcasting stations and machinery; it can be intermittent or continuous.

 

Noise creates empty spots and errors in programs and in data files.
