What Should I Pay Attention To When Buying A Static Voltage Stabilizer?

What should be paid attention to when buying Static Voltage Stabilizer? Compared with other types of voltage stabilizers, static voltage stabilizer products have the advantages of large capacity, high efficiency, no waveform distortion, balanced voltage regulation, etc. They are suitable for a wide range of loads, can withstand instantaneous overloads, can work continuously for a long time, manual/automatic switching, overvoltage protection, phase loss, phase sequence protection and automatic mechanical failure protection, reliable operation, etc. When purchasing static voltage stabilizers, the power consumption is generally very large, such as factories, construction sites, docks, etc. Many of them are used in inductive load equipment. At this time, it should be noted that since inductive loads have a large instantaneous starting current, which is generally about 3-5 times the rated current and often exceeds 9 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, compressors, etc. must consider their power reserves. If there is a margin, it is necessary to reserve enough margin to avoid the impact current generated when the load is turned on. The voltage stabilizer causes immediate damage to the voltage stabilizer. When purchasing a static voltage stabilizer, you should consider whether it is designated for a single device or for the entire plant's electrical equipment. If the entire plant uses a static voltage stabilizer, when starting the machine, you should avoid starting a high-power inductive load at the same time. Therefore, when purchasing a voltage stabilizer, you should have 1.5 times the 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 difference is within the voltage regulation range. Before purchasing the machine, you should consider future business expansion, whether you need to add equipment, and whether the voltage stabilizer needs to reserve expansion capacity. Whether it is a single machine or a whole plant, the selected voltage stabilizer should reserve a certain amount of reserved capacity to avoid a 100% load rate for the voltage stabilizer. The load rate of the voltage stabilizer is generally 90%, which is more appropriate.
