25 hp (20 kW) 3 Phase AC Output Line Reactor for VFD

产品规格

Model No: ATO-OCR-0050-0M14-0.4SC

产品描述

15 kW output line reactors will provide some protection on slow, low energy surges but a spike of high energy and fast acting will go straight through the AC line reactor, maybe taking out the rectifier, IGBT or if you are lucky the drive will trip.
A number of VFD's have built in DC link reactors and so the harmonic performance is as good as fitting a 5% AC reactor except you do not get the voltage drop effect that DickDV mentions. Fitting an AC line reactor to a VFD that has DC link Reactors does not improve the harmonic performance that much and the downside of voltage drop and lowering the efficiency of the VFD system is an important aspect.

3 phase output line reactor used to protect the motor and/or cable from voltage spikes generated from the drive, particularly with long (greater than 70 foot) cable lengths. They also assist with preventing ground leakage of drive output voltage resulting from line reflections that can rise to more than 1800 volts with a 480 vac drive system. The suppression also helps reduce motor bearing currents and voltage stresses on the motor windings. dV/dT filters provide more protection.
