When choosing a stabilizer please note the following recommendations
the nominal power of the stabilizer must be 30% higher than the power of the consumer at an active load (heaters, electric ovens, furnaces, stoves, etc.). This is due to the high starting current of the loads. When the load is switched on and in the case of short-time modes, the short-time load significantly exceeds the nominal parameters indicated in the load characteristics. This requires the use of a stabilizer with a certain reserve of power, especially in locations where the voltage at the input of the stabilizer is in most cases close to the lower limit of the input voltage range.
when the voltage stabilizer is used to supply an inductive load, the selected stabilizer should have 3 to 5 times the output power of the load load! (luminescent and fluorescent lighting, electric motors, pumps, air conditioners, refrigerators and freezers, etc.).
when the voltage stabilizer is used to supply a capacitive load, the selected stabilizer must have a 5 to 10 times higher output power than the consumed load power! (pulse chargers, LED drivers, pulse power supplies, etc.)
If these conditions are not met, the stabilizer may be overloaded and damaged and the warranty will not cover the damage.
