7.With temperature protection (NC aux. contact)
Before use Reactor
Drives are susceptible to problems caused at their interface to the line or motor.
Some of these issues include AC voltage waveform line notching or cross-talk, DC
bus overvoltage trips, inverter overcurrent and overvoltage, and poor total power
factor. Since all drives demand nonlinear current and voltage, drives demand currents
rich in harmonics.
Three phase AC reactors are intended for use as input filters for adjustable speed DC drives and as input or output filters for AC-PWM variable frequency drives. Drive performance is significantly improved, the drives input rectifier is protected from failure or damage, and drive harmonic demands are tamed with the addition of a K-rated reactor. KLR reactors act as interface buffers between solid state power circuits and the line or the motor. (Not unlike the surge protector for your desk-top PC). All drives, in any application, will benefit when applied with this reactor.
