Highlights of Uninterruptible Power Supply (UPS) and types of UPS

Highlights of Uninterruptible Power Supply (UPS)

UPS is a device that provides emergency power at the time of power-cut or power source failure. They are unique from generators or power systems because they provide protection to the connected equipment by using a battery. APC UPS is the most recommended UPS to protect the devices from damaged caused due to power failure.

The battery itself ordinarily has a short runtime (around 5-20 minutes), yet it should sufficiently be to either spare such valuable information/progress that you have made, effortlessly shut everything down, or fix the difficulty that caused the blackout. 

An APC UPS can be utilized to secure equipment like PCs, and other electrical gear where an unexpected surge or power failure can cause difficult issues like data loss or can even cause damage to the equipment.

Types of UPS

Double Conversion UPS 

Here the AC/DC inverter is always associated on. This implies there will be no exchange time between the power source and battery, giving more prominent insurance against power failure. The DC current stream is then taken care of through an inverter stage that remakes the 230V AC mains yield. Since the AC yield is totally recovered, it will be totally liberated from any mains-borne obstruction, for example, spikes and voltage varieties.

Advantages of Double Conversion UPS:

  • Nonstop and all-out force molding
  • Safeguard/over-burden assurance with static detour office
  • No break on mains disappointment
  • Wide information voltage resilience
  • Suggested with Generator sets

Disadvantages of Double Conversion UPS:

  • More costly than different sorts of UPS innovation

Standby UPS

Standby UPS provides protection against power failure and good battery backup. During ordinary tasks, it gets its capacity from its principal power source (for the most part an AC source). When it detects that the principle power source goes past adequate cutoff points or fizzles, it changes to the “disconnected/reserve” battery where it will at that point go to the DC/AC inverter – accordingly, there will be a little exchange time between the fundamental force source and battery.

Advantages of Standby UPS:

  • Minimal effort 
  • Quiet activity when in backup 
  • Productive 

Disadvantages of Standby UPS:

  • Negligible force insurance – just ensures against a little level of issues 
  • Helpless yield voltage guideline – droops and floods will be passed directly to the heap 
  • Break move to battery mode 
  • No safeguard – UPS will drop the heap if there is a high beginning up current, over-burden, or inverter disappointment

Line-Interactive UPS

The line-intelligent UPS has a comparable plan to the standby UPS, however with properties of a double-conversion as well. The line-intelligent plan can deal with small under-voltages and over-voltages (about 20% from its standard voltage) by utilizing a multi-tap variable-voltage. During small under/over-voltages, the battery isn’t being utilized is as yet being charged until there is a major under/over-voltage.

Advantages of Line-Interactive UPS:

  • Lower cost than on the web 
  • Gives preferred insurance over disconnected 
  • Quiet activity when in backup
  • Proficient

Disadvantages of Line-Interactive UPS:

  • Changes, for example, spikes, can even now be passed directly to the heap 
  • Break on exchange to battery mode. 
  • No safeguard – UPS will drop the heap if there is a high beginning up current, over-burden or inverter disappointment

Benefits of Using UPS 

Support of Power: 

The support of capacity to all PC and electric frameworks in case of intensity blackout is the clearest and significant favorable position of having a UPS Power Supply. 

Progression of Operation: 

It is the most essential element that a UPS Power Supply can offer. The UPS keeps up the power on its batteries during typical activity when it is connected to an AC wall outlet. It likewise allows the administrators to securely close down the entire electrical equipment in case of long term usage.

Flood Protection: 

A UPS gadget can continually detect spikes and monitor the approaching voltage because of its hardware. It reconnects its output to the incoming force from the wall when the spike or flood power is no more. 

Less Interactive UPS: 

To clean the approaching power before sending it to the output, the improved type of UPS known as the line intelligent UPS is utilized. It guarantees that the entire electronic frameworks are not liable to power failure after the changes are done in the output.

Bad marks of UPS: 

Start-Up Cost: 

For installation of UPS in large corporate huge investment is required. Even UPS for the home can require thousands of rupees.


Very little arrangement is needed for home UPS gadgets however on account of enormous corporate UPS gadgets, there are numerous extra thought which costs high 

Cost of maintenance: 

UPS batteries don’t keep going long and should be changed when required. The life span of a UPS battery relies upon the battery model. 

Energy Use: 

The UPS should draw more power than the interest of the joined hardware to keep the UPS batteries charged all time. This is a huge extra expense as there is tremendous misuse of intensity.
