For more information, please visit ZHONGKANG.

The popularity of uninterruptible power supplies (UPS) has risen significantly in recent years. Not just for businesses, but for home users as well, who often have limited power setups such as houseboats, pop-up offices, and mobile homes. The value of having a safety net for your power-consuming devices is undeniable. Additionally, for those whose data is critical and whose business or personal life relies on constant access and read/write operations, a UPS can provide peace of mind. In the past, power failure solutions were only accessible to large enterprises and high-level businesses, with prices starting in the five figures. However, with the rise of network-attached storage (NAS) in homes and the increased efficiency of mass production techniques, owning a UPS device to protect data in both homes and businesses has become more affordable. However, choosing the right UPS for your NAS device, such as a QNAP or Synology, and finding one that fits within your budget can be challenging. In this guide, we will address the three commonly asked questions by users considering a UPS but unsure of which device to choose: 1) How does a UPS work and how will I benefit? 2) How do I determine the right Watts, Volts, and Amps to choose the best UPS? 3) How much will a UPS cost? We hope this guide is helpful for NAS buyers looking at brands such as Synology, QNAP, Asustor, Terramaster, and others, and also for anyone looking to choose the right UPS for other devices.

What Are the Factors I need to consider when buying a UPS for my NAS?

Choosing the right UPS (uninterruptible power supply) for your Synology or QNAP NAS (network-attached storage) can be a complex task, as there are many factors to consider. However, by following a few key guidelines, you can ensure that your NAS is protected against power outages and other issues that could cause data loss or corruption. The first thing to consider when choosing a UPS for your NAS is the amount of power that your NAS requires. Desktop NAS devices with external PSUs typically have a power consumption of around 60-120 watts and rackmounts generally 250W and above, although this can vary depending on the specific model and the number of hard drives that are installed. It is important to choose a UPS that can provide at least this much power, as well as a bit extra to account for any other devices that may be connected to the NAS. Another important factor to consider is the runtime of the UPS. This is the amount of time that the UPS can keep your NAS running in the event of a power outage. The runtime of a UPS is typically measured in minutes, and you should choose a UPS that has a runtime that is long enough to allow you to properly shut down your NAS in the event of a power outage.

Another important feature to look for when choosing a UPS is the ability to communicate with the NAS. Some UPS&#; have built-in USB or serial ports that allow them to communicate with the NAS and provide status information. This can be very useful in case of power outage, as it can allow you to monitor the status of the UPS and take appropriate action. Finally, you should also consider the size and weight of the UPS, as well as its overall design. A UPS that is smaller and lighter may be more convenient to deploy, but you should also make sure that it is well-designed and built to last. When choosing a UPS for your NAS, it is important to consider the amount of power that your NAS requires, the runtime of the UPS, the ability to communicate with the NAS, compatibility and the size and weight of the UPS. By following these guidelines, you can ensure that your NAS is protected against power outages and other issues that could cause data loss or corruption.

What is a UPS and Why Should I Buy One for my NAS?

The most frequently asked question about UPS is typically &#;What exactly is a UPS and what does it do?&#; UPS stands for Uninterruptible Power Supply and many users believe that purchasing a UPS means they can run their devices and access data from their NAS, DAS, or SAN for hours after a power failure. While this is technically true, it would require a significant financial investment in the form of a 5-figure sum. In reality, most users do not require hours of protection for their read/write data operations on HDD media. Instead, what is often needed is enough time to safely shut down the server or RAID storage. This can be achieved by spending only hundreds of pounds, not thousands, as it depends on the number of devices drawing power, their specific needs, and the efficiency of the chosen UPS. For more information on UPS and how to choose one, please watch the video below.

How Does a UPS Draw Power and How Do I Connect My Devices?

This topic can be challenging for some, so we will break it down and explain it in a simple way. Before delving into technical terms like Watts, Volts, and Power, let&#;s use an analogy that&#;s easy to understand. Imagine receiving electricity to your device as drawing water from a tap.

To understand this concept, we can use an analogy of a tap and water. Just like a tap needs water and pressure to deliver it through the pipe, an electrical circuit needs electrons and voltage to deliver electricity to a device. The water represents the electrons that carry electricity from the power source to the destination device, like a NAS, DAS, or PC. The tap represents the destination device and the water/electrons are going around in a circuit back to the water/power source, which is mostly unseen in the cables.

The pressure in the analogy represents the VOLTAGE, which is the strength of the electricity being pushed by the electrons in the circuit. It&#;s important to measure this as some devices are designed to only accept a specific amount of voltage. If the voltage is too high or too low, the device will not function correctly.

AMPS represent the amount of electrical charge that passes a given point in a second, similar to how much water passes through the pipe per second.

So, now we need to know the WATTS of the device. This is compiled with the following equation:

AMPS x VOLTS = WATTS

Water Volume x Water Pressure = Water Power

If you&#;ve ever experienced weak water pressure in a shower while living in an apartment on a higher floor, this is likely due to the water pressure not being strong enough to deliver the water to the destination device. Similarly, a smaller battery pack is often measured in milliampere-hours (mAh), which represents the amount of charge available, rather than time. Using the analogy of water, this would be like a large drum of water. The amount of water and how fast it travels from the drum is not as important as the available water that can be carried over to the tap. The output and result is heavily affected by the AMPS and VOLTS, similar to the pressure of water and the maximum or minimum amount of water the tap can receive.

Choosing the right UPS Battery for your Home or Office

The majority of UPS devices have a similar setup. You connect one end to your main power outlet (3 Pin, 2 Pin, etc) and the UPS has multiple ports for connecting your destination devices (PC, NAS, etc). Inside the UPS chassis, there is one or more batteries that are charged from the wall plug, while your devices are powered directly from the wall and not drawing from the batteries unless there is a power failure. In the event of a power failure in your home or business, the destination devices will switch to drawing power from the batteries, giving you time to save your data and shut down your devices safely, protecting your digital storage from corruption or loss. It&#;s worth noting that when buying a UPS, there are many figures to consider, but the power drawn by computing equipment is typically measured in Watts or Volt-Amps(VA).

BUT

The power in Watts is the real power drawn by the equipment.Volt-Amps are called the &#;apparent power&#; and are the product of the voltage applied to the equipment times the current drawn by the equipment.

Inexpensive UPS devices typically have a shorter running time because they don&#;t provide as much charge. Mid-range UPS devices, on the other hand, offer longer charge times, more features, and additional functionality such as network alerts, internet alerts via SMS or , an LCD display, USB connectivity for maintenance, and the ability to automatically save or shut down certain NAS or PC machines in the event of a power failure, eliminating the need for manual intervention.

There is more to choosing the right UPS than matching the WATTS of your destination device and that of the UPS

UPS capacities are giving in VOLT-AMPS , not WATTS

Remember again,

VOLTS x AMPS = WATTS

Well, Resistance present in electrical load means that the WATTS cannot be matched Like for Like. So:

How do I Choose the Correct VA for the Watts on my NAS, PC and more?

You will need to consider a UPS with a VOLT-AMP 50-70% higher than the WATTS present on your destination device. Don&#;t forget to factor into your consumption any other devices that are drawing from the UPS, as this consumption is not per device, but TOTAL.

What is Line Interaction on a UPS?

Some UPS devices have a &#;Line Interactive&#; feature that can strengthen a weak or inconsistent power supply, particularly useful for those in remote areas where maintenance may be less frequent. When it comes to sizing a UPS, it&#;s important to note that equipment nameplate ratings are often in VA which can make it difficult to determine the Watt rating. To avoid oversizing the UPS, it&#;s recommended to configure the system such that the VA rating of the load is no greater than 60% of the UPS VA rating. This will prevent exceeding the Watt rating of the UPS. However, this approach may result in an oversized UPS and a longer run time than expected.

How Do Synology, QNAP, Asustor and Terramaster NAS work with a UPS?

Almost all NAS drive brands support the use of a smart UPS, connected via USB for monitoring or via the network. That said, how each NAS system reacts to a power cut and switching to the UPS battery does differ. I recently tested the CyberPower system with a selection of 4-Bay UPS systems to see how each NAS brand&#;s hardware and software react. Below is the video for each brand. Just click the video, or you can open them up in a separate tab by clicking the title.

Below are a number of tiered UPS systems for your individual power needs and budget. These are based on the Watts you need to cover and based on a single NAS of different size each.
