02:05 Posted by Unknown No comments


With the disruptions in the electric power supply, electrical equipment can easily get damaged. To avoid such risk, it is advised to install a UPS system to get high-quality, reliable power flow.
With so many types of UPS in the market, people often get confused about which UPS will be the best for their requirement. In this article, we have summed up the various types UPS along with their characteristics.

Types of UPS

·         Standby UPS

These are also known as line-preferred or off-line Ups. It consists of DC/AC and AC/DC converter, static switch, battery, surge processor and a low pass filter for reducing switching frequency. The standby power supplies provide high efficiency at relatively low cost.     
 
 
                                            
It this, AC input is considered as the primary power supply. Alternatively, in case of power supply failure, battery and inverter is used as a backup source. Normally, inverter runs on standby mode. During the power failure, transfer switch automatically shift the load to the backup units.

·         Standby-Ferro UPS

It uses a special saturating transformer having multiple power connection. The primary power runs from the AC input, moves through the transformer and then goes to the output. Inverter picks up the power load only in case of power failure. Unlike normal standby UPS, specialized Ferro transformer offers certain degree control and voltage regulation over the output waveform.

These systems are known for their line filtering and reliability. As a downside, there is a decrease in efficiency if it is coupled with the certain type of computers or generators. Also, Ferro transform itself has the risk of overheating and voltage distortion.

·         Line Interactive UPS

In this, AC power inverter and battery are continuously connected with the UPS output. Battery starts charging when the inverter is operating in reverse while AC power is at normal levels. When there is a power failure, transfer switch shifts the power flow and system gets power from the battery.
As inverter is perpetually connected to the output, UPS lowers the switching transients risk and offers additional filtering. This UPS provide high efficiency and reliability at relatively low cost and small size design. 

UPS is the best technology to get critical power supply backup. There is no single UPS suitable for all types of applications, different UPS types are ideal for different application.

UPS Systems - Source of Backup Power in an Outage

03:06 Posted by Unknown No comments


Electricity surges or blackouts can occur anytime. These can cause data loss and unwanted wear and tear on the electric equipment. Thus, there is the need for UPS systems to get uninterrupted power flow.

Finding the right ACups battery backup system is not such a simple task. To ease your problem, we have compiled a complete guide to help you purchase the perfect UPS.



What is UPS?

It is a device that consists of a battery and provides power backup in case of a blackout. Generally, they are used with computers for allowing the enough time to save the data and shutdown the device.

Types of UPS

UPS systems are categorized in following 3 types:

  • Standby (offline) UPS - It supplies AC power from the wall outlet. In the case of power failure, UPS switch to the battery. The downside is switching process can cause a momentary lapse in the power flow. Thus, they are not suitable for extra-sensitive equipment.
  • Online UPS - This is best for ultra-sensitive devices. It firstly charges the battery by taking the AC power directly from the wall outlet and converting it to DC. Later, it gives the output power by reconverting the battery DC power into AC. It offers zero power interruption and provides clean and stable output power. The only disadvantage it that this double conversion process consumes more energy than standby UPS.
  • Line-interactive UPS - This is best for brownouts, when there are momentary sags in power flow. It uses a special transformer to maintain the stable output voltage without shifting to battery mode during momentary power fluctuations.
Features to consider while buying a UPS 

  • Voltage Rating - Higher volt-amp (VA) rating means longer runtime or backup.
  • Performance monitoring - Nowadays, UPS includes a built-in display to show the essential stats such as battery health, runtime, etc. to determine the current performance.
  • Form Factor - Tower form is a small stand-alone unit perfect for home and small offices. Rackmounted form is large in size and suitable for complex commercial operations.
  • Available connections - Select the UPS that has enough outlets as per your requirements.
  • User-replaceable batteries - Like every other battery, UPS battery also stops working after a certain period. It is advisable to choose UPS with user-replaceable battery option. As this allows you to just change the damaged battery instead of purchasing a new UPS.
Before making your purchase, you must make note of equipment protection policy and Warranty.
