When selecting a device, it is important to consider the following features and parameters:

• Equipment type. The most common options include affordable relay stabilizers with step voltage regulation and more precise inverter devices with double energy conversion. Hybrid and electromechanical models are less common.
• Phase number. Household refrigerators are typically designed for connection to a single-phase electrical network of 220 V. This means that an appropriate stabilizer must be chosen.
• Power. The rated power of the stabilizer should be two or three times greater than the power of the load. This parameter is calculated taking into account the starting consumption of the refrigerator, which exceeds the constant power value.
• Stabilization speed is a parameter that indicates the amount of time it takes to stabilize the output voltage to its nominal value. The faster the speed of stabilization, the less likely the refrigerator is to experience a breakdown in the event of a voltage surge.
• The input and output voltage are important considerations, as extreme deviations in voltage can potentially damage the refrigerator. A stabilizer that can handle a wide range of input voltages and has minimal output voltage variation is able to compensate for failures and increase the lifespan of the connected device.
• Functions and features of network stabilizers for a refrigerator can include electronic protection against overheating, overloads, and short circuits, an auto restart system, a set of network filters, and digital/LED indication. Additional options enhance the quality of the stabilizer and make it more convenient to use.
