Line chokes for VFDs (Input and Output)

Apart from standard process automation, industries are also investing in “Variable Frequency Drives” for energy saving applications. It is a well-known fact that the presence of loads such as Variable Frequency Drives will generate significant magnitude of

harmonic distortions in the system, and may cause irreversible damage to other loads / equipment such as Capacitors, Transformers, Alternators, Relays, Power Supplies, SMPS etc. installed in the plant. Therefore it becomes extremely critical and necessary to limit harmonic distortions from automation / power saving equipment such as VFD’s, DC Drives etc. Most drive manufacturers propose a Line Choke/ Reactor to be connected in series with the VFD’s to reduce the harmonic current generated by VFD’s. For general purpose motors and using drives especially with long cable runs (typically over100 m), an Output Choke is recommended to maintain the voltage waveform within the specified limits.

The presence of series reactor essentially increases the input systems impedance and hence the harmonic current generated by the VFD’s reduces marginally by a factor of about 5 to 10%.

We supply chokes for all brands of VFDs, ratings up to 150kw, low voltage systems i.e.1000V. These are generally 1, 2, 3 OR 4%. Our Chokes are noiseless and help smoother operation to VFDs.

Having a team of Experience and Experts, we have been able to manufacture, export and supply a wide range of Line Chokes. Our products are manufactured using high quality raw material to suit typical need of Input or Output Chokes. In order to ensure the Quality and Performance of the product, the products are tested on various parameters.

Line Choke Manufacturer in Pune

DC Chokes Manufacturer in Pune

Being in the field of Electronic/ Electrical product lines since 25 years, we thoroughly understand the use and function of DC chokes in power Supplies, UPS Systems, battery chargers, VFDs etc. We manufacture DC chokes that smoothen the DC source and do not allow any part of AC component (ripple) to feed further (output). All this is achieved without any noise or vibrations in the DC chokes. Our DC Chokes deliver optimum results in functioning of the DC source at peak performance. High quality / low loss stampings are used while making these DC chokes.

Notable features of our DC Chokes

  • Accuracy in inductance value (-0% +20%)
  • Noiseless / vibration-free operations
  • Correct filtering /smoothening effect to the loads
  • Minimum temperature increase

Backed by the team of Experienced and Experts with advanced infrastructure, we have been able to manufacture, export and supply a wide range of DC Chokes.

Our products are manufactured using high quality raw material to suit exact requirement of Inductance value. Optimized Designs to achieve high efficient Chokes, utmost care is taken. In order to ensure the Quality and Performance of the product, every Choke is tested on various parameters including “Linearity Test” before dispatch to the clients.
