Input voltage range

The voltage range at the input of the stabilizer, at which it is able to operate in normal mode and supply a constant voltage of 230 or 400 V to the load (depending on the number of phases, see above). The wider this range — the more versatile the device, the more serious power surges it can extinguish without going beyond the standard operating parameters. However, note that this parameter is not the only, and not even far from the main indicator of the quality of work: a lot also depends on the accuracy of the output voltage and the response speed (see both points below).

Also note that some models may have several modes of operation (for example, with 230 V, 230 V or 240 V output). In this case, the characteristics indicate the "general" input voltage range, from the smallest minimum to the largest maximum; the actual ranges for each particular mode will vary.

In addition, there are stabilizers that can operate outside the nominal input voltage range: with a slight deviation beyond its limits, the device provides relatively safe output indicators (also with some deviations from the nominal 230 or 400 V), but if the drop or rise becomes critical, it works appropriate protection (see below).

Output voltage accuracy (±)

The largest deviation from the nominal output voltage (230 V or 400 V, depending on the number of phases), which the regulator allows when operating in the normal input voltage range (see above). The smaller this deviation, the more efficiently the device works, the more accurately it adapts to “changes in the situation” and the less voltage fluctuations the connected load is exposed to.

When choosing for this parameter, it is worth considering first of all how demanding the connected devices are for voltage stability. On the one hand, high stability is good for any device, on the other hand, it usually means a high price. Accordingly, it usually does not make sense to buy an advanced stabilizer for an unpretentious load like light bulbs and heaters, but for sensitive devices like audio systems or computers, it can be very useful.

Grounded sockets

The number of sockets for 230 V with grounding provided in the design of the stabilizer.

Some electrical appliances, such as refrigerators and washing/dishwashers, must be grounded when connected. This point should not be ignored — there is a risk of a serious electric shock. Accordingly, the number of sockets with grounding corresponds to the maximum number of such devices that can be simultaneously connected to the stabilizer without the use of splitters. At the same time, ungrounded devices can also be connected to such sockets.

Carrying handle

The presence in the design of the stabilizer of a special handle for carrying the device from place to place. This feature is useful primarily for powerful and, accordingly, heavy devices, which would be inconvenient to hold directly by the case. And in the most "weighty" models, which are not designed to be carried alone, there are several handles.
