What Is Inverter Output Reactor？
The ZHIMING OCL Series Inverter Output Reactor is an electrical component installed between a variable frequency drive (VFD) and the motor it controls. Built with high-quality imported silicon steel laminations and high-purity copper windings, this Inverter Output Reactor suppresses the steep voltage rise rate (dV/dt) of PWM output waveforms and limits capacitive charging currents in long motor cables. By smoothing the inverter output waveform, it improves power quality, boosts the system power factor, and protects motor windings from insulation stress. Compact, quiet, and thermally efficient, the OCL Series complies with IEC 289:1987 and is suitable for a wide range of industrial drive applications.

FAQ
What does an Inverter Output Reactor do in a VFD system?
The OCL Series Inverter Output Reactor is installed between the VFD and the motor to limit the voltage rise rate (dV/dt) of PWM output pulses and reduce capacitive charging currents in long motor cables. This protects motor insulation from premature aging, reduces electromagnetic interference, and improves overall power quality.
What motor power range does the OCL Series cover?
The OCL Series spans 24 models covering motor adapters from 0.75kW to 450kW, with rated currents from 8A to 1100A. Custom designs beyond this range can be produced upon request.
What is the noise level of this Inverter Output Reactor?
The OCL Series is designed for low acoustic noise emission, measuring less than 35dB at a distance of 1 meter horizontally from the reactor. This is achieved through core clamping, precision winding tensioning, and full vacuum pressure impregnation.
What insulation and voltage withstand ratings does it have?
The Inverter Output Reactor features Class F or H insulation and passes a 3000VAC / 50Hz / 60s dielectric test between core and winding without arcing or breakdown. Insulation resistance exceeds 100MΩ when tested at 1000VDC.
Can I order a custom Inverter Output Reactor with non-standard specifications?
Yes. The data table represents typical models, but ZHIMING can design and produce OCL reactors to meet special requirements including non-standard current ratings, voltage ratings, mounting dimensions, and environmental conditions.
