The unit comes ready to use straight out of the box as its battery comes connected to the internal power cords.
What Could Be Better:
The unit does not restart automatically. When the full line voltage comes back and the battery gets depleted then when you shut off the unit, it does not restart on its own. We feel it could be a deal breaker to some people. It also does not come with a USB charging port. Also, when you plug it in, you get a faint but audible transformer buzz which can be so annoying.
Things to Consider
There are a few aspects that you must consider to get your UPS right. If you are new to UPS systems and their operation, consider this buying guide an introduction to their basic concepts. You will also get to know the one that matches your needs.
What is UPS?
A UPS (Uninterruptible Power System) is a battery backup power system that supplies power to electronics long enough for them to shut down properly whenever there is a blackout or the utility power fails.
A UPS system is handy as it helps prevent loss of important data, saves time and materials in 3D printing and reduces the stress a hard shutdown causes on your electronics.
A UPS is also a surge protector. It protects your connected electronics from power problems like abnormal voltages which can damage or reduce their lifespan.
How Does a UPS Protect a 3D Printer?
A UPS protects a 3D printer from the stress of a hard shutdown. In case of a blackout, the printer will continue running and finish printing the build.
If the printer is not running but it’s on, the UPS will give you time to shut it down properly. Some UPS systems are also capable of protecting a 3D printer from surges and other power problems that can damage it or reduce its lifespan.
How to Choose the Best UPS Unit for Your 3D Printer
You wouldn’t know the best UPS for your 3D printer without knowing the essential features that make up a good one. The features include:
There are 3 main types of UPS systems based on topology or categories according to the type of power protection you need. The 3 topologies are: line-interactive, double conversion, and standby.
Line-interactive and standby UPSs can only provide short periods of battery runtime whenever there is a blackout. When utility power fails, they turn on the inverter which prevents interruption by producing power. They are best for protecting non-critical electronic devices.
Double Conversion, also known as online UPS, provides the best level of power protection for all of your critical electronic devices. It operates on AC/DC power seamlessly and constantly regenerates new and clean AC power through its continuous duty inverter.
If you are a technical geek who owns more electrical devices than just your 3D printer then you want to invest in the best battery backup for 3D printer that offers a huge power capacity. Whenever utility power fails or you get a blackout, the UPS will have enough power to allow the graceful shutdown of all of your critical devices. A 1500VA/900 unit like the Tripp Lite SMART1500LCD would suffice.
This is number of minutes a UPS can support all of your connected devices with power whenever there is a blackout. The number of watts supported affects runtime. A UPS with a large wattage load will have a short runtime.
The minimum runtime for a decent UPS system should be 5 minutes, the required runtime 30 minutes and the potential runtime 60 minutes.
This is a crucial feature. It exists in UPS systems mostly for safety reasons. It is used to transfer electrical power from a source of AC power to some equipment or device while isolating it from the power source. In essence, it prevents the load from generating harmful harmonics and only clean power is provided at the output.
Almost all UPS systems feature surge protection. Surge protection is crucial as it keeps your connected devices safe from the effects of a power surge. A UPS system with 10 outlets like the Amazon Basics Line-Interactive UPS will have 5 surge protectors. One with 8 will have 4 surge protectors.
If you are planning to connect a network device like a modem or Ethernet then you must ensure you get a UPS system with enough power output and runtime otherwise, they will go down.
Management software makes the UPS system easy to operate. You can access all the information about the unit and even customize alerts using the app. Most units come with a free download and they are usually compatible with various devices that you can connect to via USB.
Dimensions and Weight
This is an essential factor, especially if you have a small workspace cramped up with lots of electronics. If that’s the case, then you want to invest in a lightweight and compact unit like the Amazon Basics Line-Interactive UPS that can fit neatly into any space.
If you have no issue with space, then you can go for the likes of Tripp Lite SMART1500LCD that are large and heavy.
Different manufacturers offer different types of warranties for their US systems and batteries. The standard warranty period is 2 to 3 years on electronics and 2 years on batteries. Some like Amazon only offer 1-year warranty. Be sure to go for the best warranty deal. Some manufacturers believe in the quality of their products so much that they offer advanced replacement warranty.
UPS systems come with varying price tags. They can cost anything from 1500 to 250000. Home UPS systems are the most affordable. They provide battery backup for devices for a short time, just enough for you to save your data. Online UPS systems are the priciest because of their massive power loads. They are used by large firms.
Before you choose a UPS system, you must establish the number of devices you intend to connect to it. Most units will have more than 8 outlets, but then again you must check the number of outlets that are battery powered.
Yes. Just like any other electronic device that needs power backup, you can plug your 3D printer to a UPS.
A UPS system will prevent your 22-hour print from getting damaged when your utility power fails, and protect your printer from power surges. Our Editor’s Choice, the CyberPower CP1500AVRLCD is a line interactive UPS system with enough power to support and protect your 3D printer and any other electronic devices you have.
