Input Line Reactors
The addition of a line reactor, sometimes known as a choke or inductor, helps protect your equipment from input power disruptions that damage the drive.
Line reactors are electro-magnetic devices which consist of a steel core wrapped with copper coils. The coils form a magnetic field which current flows through limiting the rate of rise of current, reducing harmonics and protecting additional electrical devices. There are generally two types of line reactors used with VFDs; AC & DC.
When a reactor is installed between the power system and the VFD, it is known as an AC line reactor. When a DC reactor is inserted into the DC link of a drive, it is known as a DC link reactor.
Both AC and DC reactors act as harmonic current limiters but the AC reactor protects more equipment due to being installed between the VFD and power source limiting exposure to power system surges and fluctuations. This limits exposure to power system surges and fluctuations. Reactors can prevent overvoltage trips, increase the reliability and life span of the VFD, improve total power factor, and reduce nuisance tripping.
Product Features
- Enclosed coils completely enclose the Line Chokes coils against moisture, dirt, dust, and industrial contaminants for maximum protection in industrial environments.
- Mounting Clamps are made of heavy steel to add strength to core construction and provide stability. Slotted mounting feet permit easy and flexible installation.
- Attractive epoxy coated black matte finish, easy-to-read label with complete technical details.
- Constructed with high-quality silicon steel laminations to minimize core losses and increase performance and efficiency. The core is constructed using the “Hole-Less” method thus minimising the magnetic reluctance and decreasing the No-Load Current (NLC) and No-load Watt Losses. This will help give a performance with minimum vibration and humming Sound.
- Super Enamelled Copper or Aluminium wire of the highest quality assures efficient operation.
- Every Line Reactor is tested at a full rated current. This enables us to determine the exact Airgap required and also indicate the functioning of the Inductor at rated current.
