  • It lasts nearly 5 even while taking a 900W load
  • Free downloadable software for advanced alert


  • No aftermarket batteries are available for this case or rack

Can the rack UPS work on low voltage?

When your home’s voltage drops below 80 volts, the SMART100LCD can still function properly. On the other hand, the system can also support networking devices when the voltage exceeds 140 volts.

Is there a fan to cool the unit?

One fan is located at the back of the casing. It remains on constantly. The drawback of this fan is its excessive noise.

Overall Opinion: This device is good and suitable for small network security and power backups. As a result, it has enough features to facilitate and secure the use of small computers, routers, hubs, and some cables.

CyberPower OR700LCDRM1U Smart App LCD UPS

Nowadays, most UPSs utilize sine wave technology. But this OR700LCDRM1U uses a simulated sine wave function for more excellent stability and data security. In general, powerful batteries can damage data transmitted by networks. That is why the manufacturer has integrated this feature to ensure both power and data security.

The product is not expensive but purchasing the product and the accessories would be an additional expense. Since this case is constructed of high-quality steel, it does not absorb heat or static electricity. As a result, the heat is dispersed, and the internal components remain in good condition for an extended time.


  • Around 30 seconds of backup with a full load.
  • Multiple inputs at the bottom for better power regulation to devices.
  • Universal fit size.


  • The battery isn’t durable and drains a lot after some time.

Simulated sine waves can make the whole machine more energy efficient. Thus, the product ensures zero energy loss.

What is the purpose of the data line protection input at the back of the case?

Sometimes, LAN cables can transmit power surges that can damage both data and hardware connected to the UPS or the source. The option provides a data line protection input that prevents surges from spreading as a solution to this issue.

Overall opinion: UPS batteries are not inexpensive these days. They usually cost hundreds of dollars to replace. OR700L has a weaker battery that is not fully compatible with the features it promises to provide. Other than that, the system is wonderful.

Tripp Lite 500VA Smart UPS Back Up, 300W Line-Interactive

What makes this product special? Why are we recommending it? This model is characterized by many intelligent features as well as durable components. Everything is pretty standard and acceptable for network power backups except these.

This model is suitable for small IT vendors who need to provide continuous service to their customers, even in the case of a short-term power outage. The battery and system can detect the voltage consumed by a device connected to the battery. Thus, the UPS will cover the same amount without a microsecond’s pause whenever a power outage.

Due to the automated voltage fixer, the UPS maintains normal energy flow even when the power supply becomes unstable. Therefore, it mainly helps prevent data corruption from energy overflow or underflow.

Does this UPS take up a lot of space?

As a compact design, it is compatible with most racks. Moreover, it takes up barely one rack space.

Overall opinion: Despite the manufacturer’s assertion that this product is suitable for business purposes, I do not find this statement to be entirely accurate. Despite its stability, I think it would be desirable for users working on data science and networking at home simply.

APC 1500VA Smart-UPS with SmartConnect, SMT1500RM2UC

APC is undoubtedly known for those who are researching a good rack mount UPS for quite some time. It is one of the most reliable UPS manufacturers. The SMT1500RM2UC is an upgraded version of the 1500-UC.

Is the product capable of operating without any monitoring?

With this UPS, you can keep your business’s entire server or network connection online. The integrated software alerts you whenever there is a problem. If this occurs, you will have to resolve the issue manually.

Why does this model provide such a large amount of power backup?

Around three hours of support in a 100W load might seem excessive. However, in commercial sectors, where many hubs and stations are connected, a powerful backup is necessary to mitigate the effects of power outages or voltage fluctuations.

Overall opinion: Although it can monitor the entire network’s power distribution, you need to observe it with your own eyes from time to time. However, the feature truly makes it one of the best UPS models.

Tripp Lite SMX1500LCD 1000VA Intl UPS Smart Pro Rack

This is a UPS set that you can buy all in one package. The price of this model might seem high, but the features it offers make it worth the investment. It is hard to find anything lacking from this UPS. It provides:

  • Innovative technology.
  • A durable case.
  • A long-lasting battery.
  • All of the other features you might expect.

  • Works with the latest computer OS for mobile observation
  • Every mount accessory integrated with the UPS
  • Socket inputs placed at a reasonable distance between each other


  • Might not adapt universal power standard

Is it necessary to customize the software manually?

It is impossible to customize the software used to maintain the UPS remotely. It only has one operating mode. However, it can still be helpful in many scenarios.

What is the cost of this UPS set with mounting?

This set is quite overpriced when compared to other top-rated products. However, even after that, I recommend it mainly due to its proper and sustainable characteristics.

Overall opinion: Despite its budget, the product looks good and is durable from several perspectives. Therefore, this rack mount UPS may be a good choice for home and office uses if money is not a significant factor.

APC 1500VA Smart-UPS with SmartConnect, SMC1500-2UC Rack Mount UPS Battery Backup

The UPS software can read how much power a connection has consumed. In addition, the user can receive push notifications regarding this information.

Is APC 1500VA sufficient to power a 100W load for one hour?

Actually, the battery and distribution system ensures that the UPS can support a 100-watt load for more than 2.5 hours. This is an outstanding feature of the product.

Overall opinion: This product is capable of handling a whole mini-networking setup. It has built-in software that informs users of the current status. However, getting used to the functions, software, and mounting system may take some time.

Tripp Lite 2200VA Smart Online UPS

The Tripp Lite 2200VA is a good product at a reasonable price. However, the product is designed primarily to support server and networking hardware. As a result, the model might be difficult to use for large database systems in the short term. But so far, it has zero records of failing too often.

However, there is the option to extend the battery life if you wish. This feature somehow makes the power supply system better than the average one.


  • No less than 15 minutes of backup
  • Proper voltage regulation for stability
  • LED battery life indicator


  • Less powerful battery

How long will the UPS run with a 100W load?

More than two hours! But the answer actually depends on what you intend to do with the product. As mentioned earlier, Tripp Lite may fail to receive energy backups for large DBMSs and cloud servers. Therefore, using small or mini office networks with this model is better.

Is the battery durable?

The battery will not last very long if it is continuously used for heavier loads. Therefore, the manufacturer has added a feature that allows the user to attach an external battery when they are concerned that their system will require more power during sudden blackouts.

Overall opinion: The product is pretty supportive and stable for most common applications. However, it cannot support power-hungry devices in sudden situations.

CyberPower PR750RT2U Smart App Sinewave UPS System, 750 VA

Although not really, when the battery is fully charged, you can expect almost two minutes of backup, regardless of whether your connected devices are telecommunication devices, routing systems, smart security systems, etc.

Is the model simple to use?

The UPS offers you the possibility of customizing the functions. For example, you can see them on the LCD screen, which might be a bit confusing. Surprisingly, the screen can also be tilted for a better viewing experience.

Overall opinion: It is simple to control, observe, and resolve any issues related to this product. However, you must know the UPS system to accomplish this task. Although 750W operation isn’t a wrong choice, you may want to consider this one for solid support.

APC UPS 450VA Smart-UPS SC, 120V – 1U Rackmount

One of the most powerful UPS models specifically designed for networks. A vital feature of the PAC 450 VA is its continual performance. The system can reasonably diagnose a situation with a suitable sensor, and the system can keep performing its typical functions.

  • Reads frequency variation pretty well.
  • Load capacity (280W) is consistent
  • Easy to mount and run


  • Too heavy

How much hardware can you attach to it?

There are four plug inputs on the back. Therefore, it is clear that it cannot support more than four hard net devices simultaneously. But sometimes, people can use more than four with the assistance of converters.

Is this option capable of providing emergency power to a desktop?

Although a quality system of 450 VA Smart cannot support high-end computers. The system can provide emergency power to medium and large stations and network panels. However, the configuration somehow fails to run a PC smoothly, even for a few minutes.

Overall opinion: It powering up for two to five minutes is the only problem. Otherwise, everything should be okay. But you cannot expect anything more than this, even in new conditions.

Rack Mount UPS: Buying Guide

Type of UPS

There are several types of UPS, but online UPS is the most common type of rack mount UPS. It is a combination of a battery and an inverter. The battery is charged from the grid and supplies energy to the connected load.

So if the power goes out, the system will continue to run from the battery. That’s why it’s a popular type of UPS even though it is relatively cheap and effective. You will find different sizes and models of online UPS, so it’s essential to choose one that fits your needs.

Volt Range

You should consider what size of power load your UPS should have. Most companies recommend not going below 15kVA, and the bigger, the better.

Once if you know what load you need to power, it will be good to choose the right one. So always try to buy a rack mount UPS with a bigger capacity than your total power load.

Battery Backup

Battery backup is the most important thing to consider when choosing a UPS or any type battery operated device. You should choose a UPS that has enough battery capacity to run your equipment for at least 30 minutes.

If you are running a large load, you should choose one with at least 20 minutes of battery capacity. In addition, you can select a rack UPS that has an external battery feature.

Surge Protection

A good mountable UPS should have built-in surge protection. This will protect your equipment from sudden spikes in voltage. It will also protect your gear from damage caused by lightning strikes or power surges.

So check the level of your upcoming USP and ensure is it a surge protector or not.

Power Efficiency

The efficiency of the UPS is measured by its Energy Efficiency Ratio (EER). The higher the EER, the better. It’s suggested you choose a rack mount UPS with an EER of at least 10.

As you know, a rack-mountable UPS works combined with a battery and an inverter. So should buy one that is energy efficient.

Noise Operation

Noise level is another consideration factor to buy a top quality UPS. You should choose one that has a lower noise level if running a data center or any less noisy business. Lower the noise level, the better for the environment.

So try to purchase UPS that has a low noise level, especially for online UPS. You should also consider the auto-fan speed control feature which helps you to automatically adjust its fan speed depending on the temperature in the room.
