Best Computer Uninterruptible Power Supply Units Buying Guide
Before choosing the best uninterruptible power supply you should consider following options:
1. Battery types: There are two main kinds of batteries used in UPS systems – lead acid and lithium.
Lithium batteries have a higher energy density, so they can provide longer runtimes. They are also lighter, so a lithium-based UPS is easier to move around.
However, lithium batteries are more expensive, and they don’t last as long as lead-based ones.
Also, lithium batteries need to be replaced every three to five years, whereas lead-based systems can last for up to 10 years.
2. Battery capacity: The battery capacity of a UPS is measured in volts/ampere hours (VAh). The higher the VAh rating, the longer the runtime.
3. On-battery runtime: This tells you how long the UPS can continue supplying power on its own batteries before the generator kicks in.
The longer the runtime, the more time you have to switch off your computer and switch on the backup system.
You can also reduce downtime by keeping your computer running on battery, while simultaneously switching on the backup system to supply power.
4. UPS rating: This tells you how much power the UPS can supply. Most UPSes have a rating between 750VA and 10,000VA. The higher the rating, the more computers the UPS can supply with power.
5. Line-interruption rate (LIR): This tells you how frequently the UPS can be interrupted before the battery is fully drained. The lower the LIR, the better.
6. Response time: This tells you the time taken for the UPS to switch from on-battery to on-grid and vice versa. The shorter the response time, the better.
7. Number of outlets: This tells you how many devices the UPS can supply with power at a single point in time. The higher the number, the better.
8. Warranty: This tells you the period for which the UPS manufacturer guarantees free replacement of the unit in case of defects.
What else you should know about computer uninterruptible power supply units
1. What is a UPS?
A UPS is a device that provides emergency power to a load when the input power source fails. A UPS differs from a generator in that it will provide near-instantaneous power by supplying energy stored in batteries, flywheels, or supercapacitors.
2. What are the benefits of using a UPS?
Some benefits of using a UPS include:
-providing backup power in case of a power outage
-protecting against power surges
-allowing you to keep working during a power outage
-preventing data loss in the event of a power outage
3. How does a UPS work?
A UPS is an uninterruptible power supply. It is a device that provides emergency power to a load when the input power source fails. A UPS differs from a standby generator in that it will provide near-instantaneous power to the load when the input power fails.
4. What are the different types of UPS systems?
The different types of UPS systems are standby, line-interactive, and online.
5. How do I choose the right UPS for my needs?
There is no definitive answer to this question as it depends on the specific needs of your business. However, some factors you may want to consider include the size of your business, the type of equipment you are using, your power requirements, and your budget.
