It is good to have a UPS or Uninterrupted Power Supply, as it keeps your system running when the power goes down. There are different design types with different capacity, so it is crucial for you to purchase one that suits your needs. In this buying guide, we’ve addressed issues that need to be taken into account while purchasing a UPS for your system.
There are mainly three UPS design types available at Ryans. The least expensive one is known as Offline or Standby UPS. A Standby UPS unit keeps its battery charged and waits for the power to fail. When it happens, the Standby UPS mechanically switches to the battery backup.
A Line-Interactive UPS unit has a similar design but includes a special transformer that makes the UPS unit better at dealing with issues like brownouts or power sags. If you live in an area that faces frequent brownouts or line-voltage issues, it’s certainly worth the small increase in the cost to purchase a Line-interactive UPS.
An Online UPS unit is the most expensive type of UPS that completely isolates the devices attached to it from the wall power. Unlike Standby or Line-interactive UPSs, it keeps filtering wall power through the battery system. The machines attached to an Online UPS unit run completely off the battery bank. As a result, there is never a single millisecond of power interruption when there is power loss or voltage issues. The Online UPS unit effectively works as an electronic firewall between your devices and outside world and stabilizes the electricity for your devices. An Online UPS unit, however, comes with a hefty price tag, approximately 200 to 400 percent higher compared to a Line-interactive UPS unit with a similar specification.
Things to take into account while purchasing a UPS
Equipment to be plugged in
You must think about how many equipment you want to plug into the UPS before buying one. Is there anything else apart from your PC and monitor? You may need to plug in your router as well. If you have a comparatively larger home office setup, you’d probably need a UPS with more plugs/outlets compared to standard ones having two to three. Depending on your needs, you can get up to as much as 8 from Ryans.
Your UPS has to be large enough to power all the equipment plugged into it. At first, you need to find the UPS capacity, which measures how much power a UPS can provide (in watts). The higher the capacity, the more equipment, and devices it can support. Before finding the UPS capacity, you need to calculate the load, the combined amount of power your devices need.
If you are unsure how much watts your system requires, you can consult with our experts at Ryans, available 24/7 to help you out.
The Runtime is the number of minutes a UPS can support the attached devices with electricity during a blackout. If shutting down your devices with safety is all you care about, then a standard UPS will certainly be able to meet your needs. But if you also want to run your system during a blackout, it is crucial to opt for a UPS with higher runtime. Keep in mind the number of watts supported affects runtime: the smaller the wattage load connected, the longer the batteries will last. The larger the wattage load, the shorter the runtime will be.
There are several primary areas to consider when purchasing a UPS. If you find it difficult to pick the right one that fits your need, Ryans Executives are available both online and offline to guide you to make an informed purchase within your budget.
