Buying Guide: Things You Should Consider Before Buying a Rack Mount UPS

Online UPS:

The 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 on the battery. This is the most popular type of UPS because it is relatively cheap and effective. There are many different sizes and models of online UPS, so it’s essential to choose one that fits your needs.

Range in-between 15-20kVA:

You will need to consider what size of load you need to power with the UPS. 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 load.

Battery Backup:

The battery backup is the most important thing to consider when choosing a rack mount UPS. You will need to select a UPS with enough battery capacity to run your equipment for at least 30 minutes. If you are running a large load, you should choose one with 20-30 minutes battery capacity. In addition, you can choose a rack mount UPS that has an external battery feature.

Surge Protection:

A good rack mount 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.

Power Efficiency:

As you know, the rack mount UPS combines a battery and an inverter. So you need to choose one that is energy efficient. 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.

Quiet/Low Noise Operation:

It is most important to consider the noise level of the rack mount UPS. You should choose one with a low noise level if running a data center. The lower the noise level, the better. So always buy a rack mount UPS that has a low noise level. You should also choose one with an auto-fan speed control feature to automatically adjust its fan speed depending on the temperature in the room.

So these are the things you should consider before buying a rack mount UPS.
