2. Product Major Parts
The voltage regulator is composed of many parts, the following description mainly focuses on the major parts of this product.
Copper coils for voltage regulation: there are three copper coils regulating each phase independently.
Servo motor for driving the carbon brush to move along the surface of the copper coil: the servo motor plays an important role in pushing the carbon brush to move when the voltage fluctuates.
Carbon brush for voltage regulation through co-working with copper coils: three carbon brush moves along the surface of the copper coil to realize voltage stabilization even when the power supply is not stable.
Enclosure: this part protects all the major components of the voltage stabilizer from being damaged.
Wiring terminals: the terminals is very user-friendly. It’s very easy for users to connect wires because there are clear indications of how to connect wires.
Air switch: this part plays a role in protecting the voltage regulator and latter load equipment because it would trip when there is over-current or short circuit.
