2. Introduction


This 300KVA voltage stabilizer belongs to SBW Series product. Its rated capacity is up to 300KVA, which could bear a load of many large-capacity electrical equipment. It is a three phase industrial voltage stabilizer/regulator which is often used with industrial appliance.


The input voltage and output voltage of this 300KVA voltage stabilizer is 380V±20% and 380V±2% respectively. However, the voltage could be customized according to real conditions. For example, the input voltage range could be larger or narrower. The output voltage could 415V or 440V or any other voltage that you designate.


The working theory of this high power industrial voltage stabilizer is like follows: if the input voltage changes, the servo motor drives the chain to move up and down, which could change the position of the carbon brush. When the carbon brush moves along the copper column, the voltage could be regulated at a certain value.

3. Main Characteristics


① Strong load-bearing capability: the industrial voltage stabilizer has a rated capacity of 300KVA, which could bear a large load.


② Fast reaction speed to voltage change: when the input voltage fluctuates, the stabilizer could react within one second.


③ Full protection functions: the product is designed with various protection functions, including over-voltage protection, under-voltage protection, over-current protection, time delay protection, phase failure protection etc.


④ High precision: the output voltage is very precise to the rated one, which could facilitates normal work of load equipment.


⑤ Strong electricity inductiveness: the copper column strengthens the electricity inductiveness.
