Top 10 uninterruptible power supplies (UPS)

Relatively inexpensive and compact bespereboynik from the company PowerCom. It was built according to the backup power supply scheme and does not know how to adjust the output voltage level in the main mode. It does not contain fuses, for its "reanimation" simply press the machine button. The output power of the UPS is 425 W, the battery lasts a dozen minutes of the PC. Equipped with four euro sockets, which are protected from foreign objects "curtains". The main purpose of this uninterruptible power supply is in case of a sudden power outage, to save all documents on a personal computer, and then complete the work. In addition, it is able to provide reliable protection of active network equipment. The case has a connector for a USB cable, as well as a telephone and local area network. By the way, it is possible to automatically turn off the PC when the battery charge drops below a certain level. It has the functions of automatic self-testing and protection of the battery from deep discharge.

Even an "honest" sine wave does not always guarantee the absence of compatibility problems with powerful modern power supplies, but this is not the fault of UPS. However, with the recommended bespereboynikom and such cases will be very few. We present you the classics of the "genre" in the category of gaming UPS. Far from new, but a very good-quality and high-quality model capable of protecting the conditionally average gaming PC, as well as any other peripheral or network equipment from most typical failures and disturbances in the power supply circuits. The device has a lot of advantages over competitors. For example, it can function normally when powered by a generator set. For many, the benefits of this feature are unimportant and not obvious, but “computer scientists” of the same banks will appreciate it.

The device is well administered, including remotely, allows you to configure the thresholds of protection circuits and AVR, supports fast automatic recovery in case of overload and is relatively easy to maintain.

Good inexpensive high power UPS. An acceptable option for the case when there are problems in the power supply, and there is no sufficient funding for the purchase of the same APC. The output signal has a stepped shape, but 1200 watts make it possible to count on holding the computer with a 600-watt power supply unit built according to the APFC scheme with auto-voltage. This is at least. In addition, the smaller the battery - the longer the work in the generation mode and later there is a need to replace it. This is the question of what is better: the correct sine wave of lesser power or approximated by a larger one. Any other equipment will continue to work without problems, even if the input voltage is low / high, even if it is completely lost. Of course, we are not talking about household appliances with transformers or electric motors. This UPS does not have any “bells and whistles”, but advanced users will be able to adjust some parameters with the help of bundled software.

If the predominant type of power failures is a significant deviation of the supply voltage from the nominal, and the total power consumed by your equipment is only a couple of hundred watts, it does not make sense to purchase an expensive UPS. It is possible that the best solution to the problem would be to use an inexpensive and bespereboynik, equipped with a relatively simple AVR. Such as Ippon Back Basic 650, whose automatic adjustment system can, if necessary, increase or decrease the input voltage by 15%. Of course, a companion service like a noise filter or short circuit / overload protection is recommended by the UPS. The line includes devices with Schuko-type connectors (under the euro plug) and C13 (computer), so choosing the model of work that suits your needs will not make up.

It is only necessary to take into account that the output waveform of any member of the Back Basic family is far from pure sine wave, therefore, working together with the APFC power supply units that have the so-called Auto Range (Full Range) is not guaranteed.

Powercom has established itself as a reliable supplier of energy-saving products. The Imperial Series IMP-825AP is a linear – interactive uninterruptible power supply with five sockets, telephone line protection and a USB interface. The device allows you to minimize and save work in the operating system. It has a large capacity maintenance-free lead-acid batteries, and this despite the small size! The standby power is 495 W - this means that the average personal computer with a 17 ”monitor and 150 W will work offline for 15–20 minutes. During the disappearance of electricity switching to the battery occurs within 2-4 ms. In this UPS there is a built-in AVR voltage regulator, which maintains the output voltage within the normal range, thereby not using the battery resource during voltage fluctuations in the electrical network. Pay special attention that sockets of this UPS are not standard, but special ones - computer IEC-320-C14, which some users may not like.

It is possible that some of our readers personally encountered the results of the heightened sensitivity of high-precision equipment to the supply voltage. Any problems are possible, up to the rapid exit of expensive equipment. Online trouble free servers help to avoid potential losses, and the recommended model from Powercom is a reasonable compromise between price, quality and reliability.The "three-thousand" of the VANGUARD line is also worthy of attention, but its younger representatives are not so interesting, since they have only a couple of output sockets instead of six controlled by two groups of older "brothers". If the instability of the power supply is manifested periodically, by the way, bypass technology will be necessary, allowing to increase the device efficiency by automatically turning on the inverter bypass circuit. Return to the double conversion mode of the VGS-2000XL is instantaneous. In addition, additional batteries can be connected to this UPS, while its battery life will increase in proportion to the capacity of such an “additive”.

Online, as they are commonly called models with double conversion of input voltage, uninterruptible power supply from Ippon is designed for a maximum power of a connected load of 900 watts. The UPS is configured and controlled using the display and mechanical buttons. In the operation mode, the display shows such parameters as the autonomous operation time with the remaining battery charge, battery charge level, frequency and voltage of the electric current. Equipped with eight output power connectors such as IEC 320 C13 (computer socket). It is installed both vertically and horizontally, thanks to the removable stands included in the kit. It is possible to connect additional battery models. This model is ideal for both small production facilities and residential.
