FAQ
What is the difference between an Inverter Incoming Reactor and an Output Reactor?
An Inverter Incoming Reactor (ACL Series) is installed on the line side, between the power supply and the VFD input. It suppresses harmonic currents drawn by the drive, limits inrush current during startup, and improves the input power factor. In contrast, an output reactor is installed between the VFD and the motor to protect motor windings from dV/dt stress.
What motor power range does the ACL Series Inverter Incoming Reactor cover?
The ACL Series spans 24 models covering motor adapters from 0.75kW to 450kW, with rated currents from 8A to 1100A. Custom designs beyond this range are available upon request.
What is the voltage drop specification and why does it matter?
The ACL Series has a voltage drop of 2%–4% of rated voltage (380V AC / 50Hz). This controlled impedance provides the filtering effect against harmonics and inrush currents, while keeping the voltage loss at the drive input within acceptable limits for normal operation.
How does this Inverter Incoming Reactor help with power quality?
By adding series impedance on the line side of the VFD, the ACL Series reduces harmonic current distortion drawn from the mains, limits the rate of rise of inrush current during capacitor charging, and improves the true power factor. This protects upstream transformers, cables, and switchgear from overheating and premature aging.
Can I order a custom Inverter Incoming Reactor with non-standard specifications?
Yes. The specification table represents typical models, but ZHIMING can design and produce ACL reactors to meet special requirements including non-standard current ratings, voltage ratings, inductance values, and mounting dimensions. Contact the manufacturer with your specifications for a customized solution.
