AC Output Reactor

AC Out Put Reactor (OCR)

Production introduction:
Line reactors used on the output side of a drive (load reactors)
Output reactors are recommended for operating "non-inverter-duty" motors and for any motors when the length of wiring between the AC drive and motor exceeds 75 feet. Protect the motor insulation against AC drive short circuits and IGBT reflective wave damage, and also allow the motor to run cooler by "smoothing" the motor current waveform.
Load reactors are also used on the output of AC Drives to reduce the effects of high motor wiring capacitance and to “soften” the dv/dt (high rates of change of voltage) applied to the motor windings.
This reactor is used for suppress the capacitive charging current of connection cable between inverter and motor, and passivating the voltage rising rated of PWM as well. It is mounted at the output side of frequency inverter. When the distance of cable between inverter and motor over a value, suggest installed output rector to compensate recharge current of line capacitive.
 
Product application
• Help meet IEEE 519 criteria by reducing harmonic distortion of the input line current.
• Improve input line current balance.
• Reduce nuisance drive over-voltage trips caused by transient voltage spikes and power line notches.
• Protect input rectifiers from in-rush current caused by sudden power line surges and sags.
• Extend the life of the DC bus capacitor bank by reducing the internal heating caused by ripple current.
• Protect motor windings from long lead effects when used on the drive output.
The use of line and load reactors increases the reliability, performance, and efficiency of VFD systems, extends the life of both drives and motors, and reduces the amount of energy consumed by the motor/drive system.
