Why Should We Leave Margin When Choosing A Voltage Stabilizer?

When buying Automatic Voltage Regulator, it is recommended that you reserve enough margin. For inductive loads, you should choose a voltage stabilizer with at least three times the actual power, because the voltage stabilizer must overcome the surge impact of the mains and the starting impact of the inductive load (such as mechanical equipment with motors and electric motors) in actual work.

When the voltage stabilizer is used on inductive loads, since the inductive load has a large instantaneous starting current, which is generally about 3-5 times the rated current, and often exceeds 3 times the operating current (such as refrigerators, air conditioners, washing machines, electric fans, large air conditioners, printing presses, air compressors, elevators, water pumps, etc. are all inductive loads), so all voltage stabilizers equipped with inductive loads such as motors and compressors must consider their power reserves. To leave a margin, you must reserve enough margin to avoid the impact current generated when the load is turned on. Cause immediate damage to the voltage stabilizer.

If the whole factory uses a voltage stabilizer, when starting the machine, it should be avoided that a high-power inductive load starts at the same time. Therefore, when purchasing a voltage stabilizer, there should be 1.5 times of reserved capacity, and the reserved capacity for a single machine should be 3 times. Pay attention to the voltage value of the mains power supply, whether it exceeds the input voltage range specified by the purchased voltage stabilizer, and whether the three-phase voltage differs by more than 10V.

Before purchasing a machine, it is necessary to consider future business expansion, whether additional equipment is needed, and whether the voltage stabilizer needs to reserve expansion capacity.

Whether it is a single machine or a whole factory, the selected voltage stabilizer should reserve a certain reserved capacity to avoid a 100% load rate of the voltage stabilizer. The load rate of the voltage stabilizer is generally 90%, which is more appropriate.

Professionals suggest that when choosing a voltage stabilizer, you should also pay attention to choosing a regular manufacturer, because these manufacturers have reliable quality and considerate service; at the same time, whether the manufacturer has good after-sales service, such as the implementation of three guarantees for product quality, is also an important factor that consumers should pay attention to.
