2. Major components


The major components of 20KVA single phase voltage stabilizer includes copper coil, aluminum coil, servo motor, carbon brush, enclosure, omni-directional wheels, air switch, and other essential parts.

 ① Copper coil, a very important part for this 20KVA single phase voltage stabilizer, is crucial in voltage regulation. Due to the copper material, the electricity inductiveness is strong. Also, the voltage stabilization precision is relatively high.

② Aluminum coil, plays a significant role in compensating voltage automatically when input voltage fluctuates severly. It co-works with the copper coil to provide a stable voltage power supply.

③ Servo motor, though a small part, drives the carbon brush to move along the copper coil.

④ Carbon brush, also a small component, moves along the copper coil and helps regulate the voltage. It's durable and of high quality.

⑤ Enclosure, the largest part of the stabilizer, covers all the components of the 20KVA voltage stabilizer and protect them from being damaged.

⑥ Omni-directional wheels helps you to save energy when you move the stabilizer.

⑦ Air switch plays an important role in protecting the product by tripping automatically when the current is over the rated one.
