Input Choke

Product Details:

Line/load reactors play an important role in your power system. It absorbs many of the power line disturbance, which in returns help protect many of your sensitive equipments. Line/Load reactors is also a reliable filtering solution which can help reduce the harmonic currents, generated by inverters and drives, in your system.
FEATURES

• Improved the reliability of motor drive system
• Improve power factor of the system
• Extend motor’s lifetime
• Reduce motor peak voltage, rise time, spikes, temperature and noise
• Reduce harmonics
• Protect motor from long lead effects
• Extend semiconductor life

Applications

Help in protecting VFDs & Motors from high frequency transients such as voltage spikes, pulsed distortion and harmonics

During installations which have more than two drives installed on the same power line. Multiple drives on a common power line require one reactor per drive to reduce cross talk.

Motor/Output Chokes are often installed between the motor and the drive & perform a lot of tasks, including ensuring the motor current continuity and smoothing its pulsation, minimization of the short-circuit current in converter load system as well as the limitation of commutation over-voltages and compensation of the supply line capacitance.

It is necessary to supply the voltage to drives which are located far away from the supply source. Long supply lines have higher capacitance, which contributes to a significant increase of power losses in the system. The output chokes compensate for the capacitance of the supply line and limits the harmonics and commutation over-voltages in the motor circuit. Optimal selection of its inductance has a significant impact on the operation of the entire power transmission system.

Applications

• Longer lifetime of motors
• Reduction of edge steepness dV/dT to earth and between the phases
• Reduction of motor noise
• Current smoothing
• Variable Speed Drive Harmonics Solution
