Rack Mount UPS: Buying Guide

Type of UPS

There are several types of UPS, but online UPS is the most common type. 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 of UPS

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 of A UPS

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 Capability of UPS

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 of UPS

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 you 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. The 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.

I prefer this product not only because it is affordable, but the accessories are also pretty reasonable. The case is made of high-quality steel, which prevents the absorption of heat or static electricity.

Simulated sine waves increase the machine’s energy efficiency, ensuring zero energy loss, and making it an eco-friendly option.

With this UPS, you can keep your business’s entire server or network connection online. The integrated software alerts you of any issues, which can be resolved manually.

However, it has an excellent track record and no reports of failing too often.

Plus, you can even extend the battery life if you need it! This feature makes it a better choice than the average power supply system.

How long can it last? Well, it depends on what you’re doing with it. If you’re using it with small or mini office networks, it can last up to two hours or more. But if you’re using it with heavier loads, the battery won’t last as long.

Also, the UPS has USB, RS232, and EPO slots for cards and network management if you wish.

I have found it truly useful with the true online operation and sine wave output. This device is a great option for you as it can isolate your equipment from power-related problems.

Its metal case ensures that shocks and dust won’t damage the battery. And you can easily mount the product on any rack with the help of universal mounting holes.

It only has four plug inputs, so it can only support four hard-net devices at a time. But with the help of converters, you can use more than four devices.

Unfortunately, it won’t be able to support high-end computers, but it can provide emergency power to medium and large stations and network panels. It can protect point-of-sale equipment, small switches, and networking devices from power spikes and surges.

This device is convertible between tower and rack mounting and you can use what suits you the most. I like this product for its convenient way of installation. This device is good for homes and small businesses.
