2. Major Components
 

There are many components of the voltage stabilizer: transformer for compensating voltage, copper column for regulating voltage, carbon brush for helping regulate the voltage by its movement along the copper column, drive chain for facilitating the movement of carbon brush, servo motor for driving the chain to move, circuit board for controlling the whole circuit, iron enclosure for protecting the product.

 

There are also other small parts that play important roles in constituting the voltage stabilizer. Together with those major components, all the parts play their roles respectively to enable the voltage stabilizer to perform normally.


3. Product Competitiveness


① High response rate: it reacts very quickly to voltage fluctuation. It only needs one second when the input voltage ranges between 365V to 395V.

② Strong load-bearing capability: the rated capacity of this product is 250KVA. It could bear large load and keep the voltage stable.

③ Strong instaneous over-load bearing capability: it could bear double rated load for 30 seconds.

④ High-quality material: the major components are of high quality, which prolongs the lifetime of the voltage stabilizer.

⑤ Reasonable exterior and interior design: the appearance is pleasing while the overall interior layout is well-designed.

⑥ Inexpensive price: the unit price of this 250KVA voltage stabilizer is cheap because we are a manufacturer.
