2. Product Description:


① Copper coils, carbon brushes, servo motors, circuit boards, and enclosure are major components of this three phase voltage stabilizer or three phase voltage regulator.


② Copper coils, which adjusts the output voltage, is of good electrical conductivity, making the stabilizer or regulator more stable when it works.


③ Imported 1017 carbon brushes is more durable than normal carbon brushes, facilitating a longer life of the stabilizer.


④ Servo motors of the product is of low noise and sound performance.


⑤ Three circuit boards, working with three regulating ciols respectively, controls three phase voltage independently and precisely.  


⑥ The enclosure of the stabilizer is a dustproof iron case, which protects the major parts of the product.


⑦ There are many heat dissipation holes in the enclosure, which effectively lowers the temperature of the product when it works.


⑧ The stabilizer is energy saving. Its power consumption is merely 1% of the rated capacity of the electrical appliance.


⑨ The output voltage is of high precision: 380V±2%. And the response time is leass than 1 second if the voltage fluctuates less than 10% of 380V.


⑩ There are many protection functions: short circuit, over-voltage, under-voltage, over-load, over-current etc.


3. Applications:


① Industrial factories and construction sites.


② Mining tunnels, oil fields, railway and subway stations.


③ Schools, hospitals, and hotels.


④ Research and Development Centers.


⑤Other places of which the voltage fluctuates greatly.


4. Product Selection:


How do you choose the rated capacity of stabilizer?


Firstly you could confirm the rated capacity of your own electrical appliance. The capacity of stabilizer you intend to purchase should be 1.5-2 times of the one of your appliance if the load is capacitive load. If the load is inductive one, then the capacity of the stabilizer should be 3-5 times of the rated capacity of your equipment. Please see the table below to get more information:



Type of Appliance or Equipment Start Impact Rated Capacity of Stabilizer
Capacitive load Computer, TV, refrigerator, fluorescent lamp, mercury lamp etc. 1.5-2 times 1.5-2 times of the capacity of your equipment
Inductive load Air conditioner, pump, air compressor, machine tools, printing machines etc. 3-5 times 3-5 times of the capacity of your equipment


So please identify the rated capacity of your own appliance and then choose the right stabilizer accordingly.


5. Maintenance and Aftersale Services:


① Cleaning the product (dedusting) regularly.


② The guarantee period is one year after you purchase the product.


③ If there are some tiny problems after you use the stabilizer for a period of time, we could provide parts of the products for you for free.


④ If there are some problems that you could not solve after you use the product for a period of time, we could help you to tackle with the problem through video calling within 48 hours.
