Chokes And Inductors

Product Details:

VFD Line & Load Chokes : These chokes are installed input (Line) & output (Load) side of variable frequency drives to have di/dt, impedance matching & harmonic mitigation. With these chokes the protection against the surge, transient voltage & noise to the drives are ensured. The output chokes are installed for the longer cable lengths application for example distance from drive to the load if it exceeds 25 meters. Many application like submersible pumps in Oil well, process plants needs the output (Load) chokes. The mounting geometry can be Foot or Flange mount with natural or forced air cooling.

Features :

• Can be installed on both input and output side of VFD
• Di/dt protection
• Offer impedance matching and harmonic mitigation
• Complete protection to drive from transient voltage, noise and surge currents
• Lowers the cable length requirement from drive to load
• Can be foot or flange mounted
• Option of natural or forced air cooling

Applications :

• Process plants that require the output (load) chokes
• Submersible pumps in oil well
• Line & Load applications
• VFD's - Yasakawa, Mitsubhishi, Siemens, Allan Bradlley, ABB, Fuji, Danfoss, LG and Control Techniques
• 50 Hz to > 5 kHz VFD's
• Process plants with output (load) chokes
• 3%, 5% & 7% Impedance
• Di / dt Protection Systems

Product Details:

Power Line Reactors : These chokes are used for smoothening the surge current to the load like thyristor drives, Variable Frequency drive, Servo Drives, Robotic controllers and various power electronic modules. In variable frequency drives, the line reactors are used for line and load di /dt protection along with controlling the speed and torque

Features :

• Oppose rapid changes in current
• Attenuate spikes of current
• Limit peak currents
• Suitable for electronic variable speed drive
• Extra protection to Ac and DC drives
• Reduce harmonic distortion in the input line current
• Ensure no damage to input rectifiers from in-rush current

Applications :

• Power electronics
• Variable speed drives of Mitsubhishi. Yasakawa, LG, Danfoss, Control Techniques, Fuji, ABB, Allan Bradlley, Delta and Siemens
• Thyristor drives
• Robotic controllers
• Servo drives

Product Details:

Harmonic Mitigation Chokes : These chokes are normally three phase with air gap which will act as a integrated choke which will offer additional inductance and di / dt to the load. The throw back of harmonics generated by the power electronics devices are mitigated by the unique “TransChoke”.
Harmonic Mitigation Chokes are the cost effective solution for minimizing the presence of harmonics in the electrical systems. These are basically available in three phases.

Features :

• Reduces the harmonics in electrical systems
• Available with three phases
• Ensure extra inductance
• Di/dt protection to load
• Reduces operations and maintenance costs
• Load side surge suppression

Applications :

• Line & Load applications
• Di / dt Protection Systems
• 50 Hz to > 5 kHz VFD's
• Process plants with output (load) chokes
• 3%, 5% & 7% Impedance
• Submersible pumps in oil well
• VFD's - Yasakawa, Mitsubhishi, Siemens, Allan Bradlley, ABB, Fuji, Danfoss, LG and Control Techniques

Product Details:

DC Chokes : These chokes are used for DC bus for AC ripple reduction for medium & large machines and power systems. The laminations used in these products are Electrical grade CRGO with low loss. Our prudently designed DC Chokes are suitably utilized in industrial machinery power systems for filtering the power supply. These chokes are made sturdily by making use of optimum grade copper wires terminal blocks and electrical steel laminations
