HNL Mains Choke Series

Standard HNL mains chokes must always be used whenever regenerative power supply units are incorporated at the mains.  Standard mains chokes can be installed in any position.

Standard HNL mains chokes are used in drive systems and are positioned between the power supply units and the frequency converters while current-compensated mains chokes are connected between the mains input of the power supply unit and the standard choke. The standard mains chokes must always be used whenever regenerative power supply units are incorporated at the mains. The standard and current-compensated mains chokes have their own distinct functions apart from sharing some common functions. We can help you find the right mains choke for your industrial automation needs and build one for you if needed using our proprietary tools and knowledge.


  • HNL mains chokes are designed using materials that are free of harmful elements like silicone and asbestos that can pollute the surrounding environment.
  • The mains chokes are equipped with type plates featuring details such as their type designations, nominal voltage/frequency, nominal current, number of capacitors and their ratings, certifications and more on their housings.
  • Standard Indramat mains chokes not only lower the harmonics in the mains current but also Indramat chokes help in the continuous reduction of harmonics in the line current and thereby resulting in system interferences and perturbations getting eliminated. They also assist in achieving high continuous power in the DC bus of some converters.
  • Current-compensated mains chokes come with the ability to alleviate the leakage currents or asymmetric currents in the mains connection phase of the drive system and can be used where the operation of the manufacturer’s mains chokes is not allowed.
  • Regenerative HNL mains chokes retain charge in their capacitors for a considerably long time after the power supply has been switched off.


HNL01.1R mains chokes can be connected to components with regeneration to the mains of the manufacturer’s HMV01.1R power supply units. On the other hand, HNL01.E chokes must be connected to components without regeneration to the mains of HMV01.1E, HCS02.1E and HCS03.1E power supply units. The entire range of HNL mains chokes is known for their excellent performance in any industrial setting.
