Despite the fact that household electrical networks have a high level of reliability, power outages or power surges are quite common. To protect yourself from such troubles and keep the equipment working for a long time, you can install an uninterruptible power supply. This is a special device that allows you to stabilize the voltage in the network, in addition, it is equipped with a battery of a certain capacity, which allows you to save all the data when working on a personal computer or to ensure that other equipment is correctly turned off in the event of a power outage.
In specialized stores you can find a large number of such devices, each of which has its own performance characteristics. It is quite easy to get confused in the existing variety. To make it easier for you to choose, we decided to create an overview of the best UPS of the year. Before proceeding to a direct analysis of the characteristics of such products, we decided to give the main points that you should pay attention to when buying an uninterruptible power supply.
What qualities are important for UPS in 2022?
Such a device structurally includes a control circuit and a charger that includes an inverter. It is from the power of this element that the uninterrupted supply of electricity and the switching time directly depend. Stabilizing parts equalize the output voltage. All uninterruptible power supplies can be divided into three main groups according to a number of characteristics. One of the most common products operates on the principle of an externally powered redundant circuit. It will charge the battery directly from the mains. In the event that the voltage starts to jump or disappears altogether, the UPS begins to use its own resources. Such designs are cheaper compared to the rest, in addition, they will practically not heat up during operation, they are distinguished by a high efficiency.
The interactive scheme works on a similar principle, but switching to using your own resources is much faster. The voltage shape can be both sinusoidal and rectangular or trapezoidal — depending on the brand of the device. The efficiency here is somewhat lower, the case may start to heat up when the voltage drops.
On sale you can also find designs with double conversion — these are quite expensive products designed to maintain the performance of stations with high load rates. The scheme of operation is such that at first the incoming current is converted into direct current, and at the output it again becomes alternating. It is the inverter that acts as such a converter. This mechanism is constantly connected to the network, it does not need additional time to switch to a backup power source. If necessary, you can change not only the voltage power in kW, but also its frequency. To select the most suitable UPS, you need to know the power consumed by the equipment that will be connected to it.
When compiling our rating of the best UPS, we took into account not only all these points, but also user reviews, as well as the ratio of price and quality of models. Sufficiently expensive products were not included in this review, since we also took into account the financial capabilities of people. Now is the time to start analyzing the immediate characteristics of each product.
Best double conversion UPS in 2022
3. Ippon Innova RT 1000
Products of this brand have been on the market for over ten years. This model appeared on sale not too long ago, and it has more power compared to other products of this company. It is produced using online technology (double conversion of electric current). The design is perfect not only for domestic use, but also for industrial systems, in particular, servers running on Noveli, Windows NT, Unis and so on. With the help of this equipment, it is possible to ensure the elimination of any violations and malfunctions that occur in the power supply networks. The rectifier makes the current constant, and it is in this area that the battery is charged and the inverter is powered. Based on this voltage, the inverter outputs a stable sine wave alternating current.
All connected equipment is completely isolated from the external network, but at the same time they are provided with full power. In the event that the voltage in the external network disappears, the product starts using the energy stored in the batteries, the power of which lasts for 15-20 minutes, depending on how capacious the equipment is. You can control and configure the uninterruptible power supply using a few mechanical buttons. In addition, this product is equipped with a liquid crystal display, which displays all the important information for the user — the current mode of operation, the degree of charge of the batteries, the output load power. It should be noted that this equipment is multifunctional — it is equipped with several interface ports that allow you to directly connect server equipment.

The product has small overall dimensions. On the front side, you can find only one power button. The model is designed quite simply and concisely, nothing superfluous can be found on the case, which is quite natural for an uninterruptible power supply in an inexpensive price segment. On the back side, you can find six sockets at once, designed to connect various computer devices — a system unit, monitor, printer, and so on. There is also a USB connector, two more RJ-45 connectors and a circuit breaker. There are perforations on the sides that allow you to efficiently remove warm air. Unfortunately, the fan located under the case does not have its own ventilation grill — a somewhat unusual design solution.
The central board and all other elements are close enough to each other, so forced ventilation is used to protect against overheating, which creates quite a lot of noise. The fact is that in a running UPS, the fan always rotates at the same speed, regardless of the applied load. Heating elements are equipped with radiators, but this does not eliminate the need for a fan. This device has two Yuasa REW45-12 batteries, each of them has a nominal capacity of 8 Ah, each weighs 2.7.
- High power reserve;
- Acceptable cost;
- Small overall dimensions;
- Good quality and long service life.
