Questions to Ask Before Buying an Uninterruptible Power Supply (UPS)

An uninterruptible power supply is a battery backup source that saves your electronic devices from frying during unfortunate electricity problems such as frequency variations, surges, blackouts, and abnormal voltages.

It protects the lifespan of your electronics, doesn’t allow hard shutdowns, and prevents data loss.

Do I Need One?

Have you ever failed to save a Word document on a PC to experience a sudden power surge that shut down the computer? Have you ever fried your TV during a storm-related electricity outage? Have you ever lost sensitive information from an external hard drive because of a sudden blackout?

All these disasters could’ve been averted if you had a UPS.

If you own a computer, TV, security system, or gaming console, you should consider buying at least a low-end device. It can help keep your electronics running before you turn them off manually.

How Does it Work?

A battery power source’s primary goal is to feel the surges and turn to the battery automatically before anything shuts down. The switch happens due to IGBTs (insulated-gate bipolar transistors). They’re semiconductors that provide efficiency, low voltage distortion, and stability to the UPS.

IGBTs are integral to the supply unit’s functionality. Usually, larger UPS devices can last anywhere from 12-14 years. We recommend keeping a scheduled check-and-maintenance routine to ensure you can avoid failures.

Are There Any Criteria I Should Follow?

Capacity

To determine your potential UPS capacity, account for how much load each attached device has on the overall system.

Suppose you’re supporting a PC, monitor, speakers, and external memory storage. Calculate the power each of them needs, then buy a UPS that can cover the required capacity. You also need to think about the number of electronic appliances you’re going to plug in and ensure that the unit has enough ports.

Runtime

Another crucial measure is how long you want the external power to sustain the load. The more devices you connect, the shorter the runtime.

Before choosing, prioritize your devices according to the time they’d need for a proper shutdown. It takes longer to save files and unplug a computer than to turn off a TV. Thus, we recommend you plan the sequence in which you’ll deal with all electronics.

Which UPS Type to Choose?

Some other aspects to consider are:

  • Price range and efficiency of each model
  • Usual problems in your power grid
  • Equipment’s importance

Below are the types attached to some characteristics to help you choose.

Standby: The classic, offline UPS can almost immediately switch to battery and help you maintain the equipment during short outages. Not catching minor fluctuations is the main problem here.

Line-Interactive: This version provides power conditioning (after 4-6 milliseconds) and battery backup. It effectively protects against voltage fluctuations but might not be the best type in case of outages.

Double-Conversion: This type provides power conditioning, zero-transfer time, and no change in output voltage. It’s most useful for critical IT system loads.

Final Thoughts

While many people might not realize, UPS is critical to your electronic devices’ health and lifespan in workplaces and at home. We hope that this article helped you diagnose your needs and choose adequate protection.
