Uninterruptible Power Supply (UPS)

Types of UPS:

  1. Standby UPS: also known as offline or line-preferred UPS. Basically it has an inverter, battery, static switch, low-pass filter and surge suppressor.Unless there is a primary power failure, the system remains on the standby mode.
  2. Line-Interactive UPS: contains a battery and inverter that are always connected to the output. A switch changes the electrical flow if there is a power failure. The continuous connection provides superior filtering.
  3. Double Conversion UPS: has a backup battery that is charged by the input AC and powers the output inverter for a seamless switch.

 

Purposes of UPS:

  1. Protect against power interruptions or failure.
  2. Provide adequate power during short-term interruptions and “ride-through” time to convert to backup supply.
  3. Refine the quality of the power as it reaches your building, office and equipment.
  4. Include a backup source for long-term outages, such as generators.

 

Advantages of UPS:

  1. Continuity: Experience no outages to critical equipment like computers to factory production lines.
  2. Consistency: Electronics within a UPS tells it when it needs to work and kicks in alternate power as needed, which eliminates glitches or surges and allows time to safely shut down main systems if and when needed.
  3. Protection: Safeguards against all the oddities of electricity such as surges, spikes, dips and failure because the UPS essentially senses those things and switches to alternate power before the anomalies cause damage.
  4. Filter: A line-interactive UPS acts as a kind of filter by refining the power as it comes into the UPS then adjusting its output so that internal systems receive a clean, consistent supply free of abnormalities.
