Maximum apparent load power allowed for this model
In electrical engineering, full power is called, which takes into account both active and reactive power; the first type of power is discussed above, and the second can be described as the effect of windings, inductors and capacitors on the operation of AC networks. Apparent power is the main parameter for calculating loads on equipment in professional electrical engineering; it is usually denoted in volt-amperes (VA), in the case of stabilizers — in kilovolt-amperes (kVA). Note that for convenience, different types of power in electrical engineering are denoted by units with different names. That is why the power in W indicated in the characteristics of the stabilizer is usually not equal to its power in VA.
When choosing a stabilizer for some household appliances, it is quite enough to have active power data, but if possible it is better to use the full one. In particular, it is this parameter that is key when looking for
a stabilizer for a refrigerator or
a stabilizer for a boiler : in the first case, 0.4 – 1 kVA is considered the optimal value, in the second — from 0.1 to 0.7 kVA. However, anyway, it is necessary to choose a specific model in such a way that its total power is not lower than the total power of the entire connected load — and it is better to have a reserve (in case of unforeseen circumstances or connecting additional eq
...uipment). At the same time, note that powerful models are distinguished by large dimensions and weight, and most importantly, high cost; therefore, it does not always make sense to chase the maximum numbers.
Also note that there are formulas that allow you to derive the optimal total power of the stabilizer based on data on active power and type of load; they can be found in special sources.
