Input voltage range

In this case, the input voltage range is implied, in which the UPS is able to supply a stable voltage to the load only due to its own regulators, without switching to the battery. For redundant UPSs (see "Type") this range is quite small, approximately 190 to 260 V; for interactive and especially inverter ones, it is much wider. Some UPS models allow you to manually set the input voltage range.

Max. current

The maximum current drawn by the UPS. In fact, the current reaches its maximum value only when the UPS is operating from the mains with maximum load power and a completely discharged battery. However, when calculating the load on the power grid, this parameter should be taken into account.

Output frequency

The frequency (frequency range) of the AC voltage output by the UPS. For computer technology, the frequency range of 47-53 Hz is considered normal, although the smaller the deviation from the 50 Hz standard, the better. On the other hand, in some UPS models, this frequency can be automatically synchronized with the frequency of the mains — so the power supplied to the load will not differ regardless of whether the load is powered by the mains or from the battery. In this case, a wider frequency range, on the contrary, is more desirable.

Battery in set

The absence of a battery in the UPS delivery set - to use such a device for its main purpose, you will have to buy a battery separately. This is associated with additional hassle, but it gives such an important advantage as the ability to independently select the capacity and number of batteries, without relying on the choice of the manufacturer and without the risk of overpaying for an unsuitable option.

Note that only models that do not have internal batteries and are designed for the use of external batteries (see below) can be supplied in such a configuration. These can be both professional inverter models (see "Type") and inexpensive backup models.

Battery(ies) connection to UPS

Rated voltage of external batteries that can be used in the UPS.

For more information about such batteries, see "External battery connection", here it is worth saying that the voltage of the external battery must correspond to the voltage for which the UPS is designed. If these parameters differ, at best, the UPS simply will not start, and at worst, overloads and even a fire are possible.

In general, the more powerful the UPS, the higher the voltage of the external batteries it is designed for. However, there is no strict rule. Some models even allow for multiple voltage options, such as 96/108/120 V. It is also worth noting that a power source with the required voltage can be assembled from several lower voltage batteries connected in series: for example, 3 batteries of 12 V can be used to achieve 36 V.

It is important to emphasize that the standard voltages for most modern UPS systems are multiples of 12 V. However, car batteries cannot be used in these devices. Despite having identical voltages, car batteries are designed for a fundamentally different mode of operation. Using them in a UPS can result in, at best, improper functioning of the device, and at worst, fires and even explosions.

Total battery capacity

The capacity of the battery installed in the UPS. For models with multiple batteries, this is both the total working capacity and the capacity of each individual battery: the batteries in such devices are usually connected in series, so that their total capacity corresponds to the capacity of each individual cell.

Theoretically, a higher battery capacity means the ability to power loads of a given capacity for longer. However, in fact, this parameter is more of a reference than practically significant. The fact is that the actual amount of energy stored by the battery depends not only on the capacity in amp-hours, but also on the voltage in volts; this voltage is often not specified in the characteristics, despite the fact that for accurate calculations it must be known. So when choosing, you should focus on more "close to life" characteristics — first of all, on the directly claimed operating time in different modes (see above).

Number of batteries

The number of batteries supplied with the UPS.

In general, this parameter is more of a reference than practically significant: the number of batteries is selected in such a way as to provide the desired performance — primarily the time of continuous operation. First of all, it is worth paying attention to such characteristics when choosing.

Full charge time

The time it takes to fully charge the UPS battery. Note that in this case, this time is calculated according to special rules: not from 0 to 100% of the charge, but from a state in which it is impossible to maintain half the load, up to 90% of the charge. Of course, a full charge will take a little longer. However, this data is closer to practice than the “from 0 to 100%” calculation: the inability to work at half load makes the UPS practically useless, and this condition can be taken as zero, and 90% of the battery is already able to provide a good guarantee in case of a power failure.

Cold start

The ability to turn on the uninterruptible power supply in the "cold start" mode.

A cold start is a turn-on mode in which there is no external power, and the load connected to the UPS is powered immediately from the uninterruptible battery (which, of course, must be charged). This mode is especially useful in emergency cases — for example, if you urgently need to print a document, but there is no light.
