UPS

We supply and install Uninterruptible Power Supply systems. We will ensure you have the right UPS for the role, making sure that it has enough battery backup to safely shut down the computers attached to it in the event of a total power failure.

A good UPS system will need to guard your system against the following:

• Power failure — Total loss of utility power.
• Voltage sag — Transient (short term) under-voltage.
• Voltage spike — Transient (short term) over-voltage.
• Under-voltage (brownout) — Low line voltage for an extended period of time.
• Over-voltage — Increased voltage for an extended period of time.
• Line noise — Distortions superimposed on the power waveform.
• Frequency variation —
  Deviation from the nominal frequency (50 or 60 Hz).
• Switching transient —
  Instantaneous undervoltage (notch) in the range of nanoseconds.
• Harmonic distortion — Multiples of power frequency superimposed on the power waveform.
