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.
