There are a number of reasons you may want to invest in a UPS system but generally it is to protect your critical systems from the effects of power failures, voltage dips and power anomalies.

Common power problems

The primary role of any uninterruptible power supply is to provide short-term power when the input power source fails. However, most uninterruptible power supply units are also capable in varying degrees of correcting common utility power problems:

  • Voltage spike or sustained overvoltage
  • Momentary or sustained reduction in input voltage
  • Voltage sags
  • Noise, defined as a high frequency transient or oscillation, usually injected into the line by nearby equipment
  • Instability of the mains frequency
  • Harmonic distortion, defined as a departure from the ideal sinusoidal waveform expected on the line

Some manufacturers of uninterruptible power supply units categorize their products in accordance with the number of power-related problems they address.

During a power failure your IT systems, process control and telephone systems would not operate, leading to missed calls/sales/transactions, loss of product/data or loss of staff productivity.
During power anomalies all circuits may be affected requiring systems to be re-booted, cleaned and data re-entered. The time and inconvenience caused can be a nightmare for any business.
