Overview

Single-phase DC link reactor with a rated current of 50A, low-energy-consumption design, core made of low-loss silicon steel sheets, strong impact resistance. 220V/380V/400V voltage selectable, F.H insulation class, safe and reliable. The DC reactor for vfd acts as an inductor for DC power, limiting current, reducing DC ripple, and suppressing DC harmonics. Widely used in VFD DC buses, rectifiers, and DC power systems.

Feature

Reduces DC bus ripple for more stable DC voltage.
Limits inrush current, protecting rectifiers and DC capacitors during startup.
Suppresses harmonics, reducing high-frequency harmonics on the DC bus.
Extends the lifespan of capacitors and inverter components, improving reliability.

FAQ

Q1: What is a DC reactor in a frequency converter?

A DC link choke in a frequency converter is an inductive element installed between the rectifier and the DC bus. Its main functions are to smooth DC current, suppress harmonics, limit inrush current, and protect the DC bus capacitor and rectifier components, thereby improving the stability and lifespan of the frequency converter system.

Q2: Does a DC reactor lower the system voltage?

A DC smoothing reactor generally does not significantly lower the system voltage. It is not a device used to change the voltage, but rather to limit current changes through its inductive characteristics. In actual operation, due to the influence of coil resistance and inductance, a certain voltage drop will occur, but this drop is usually small and will not affect the normal operation of the system within the normal design range. In other words, the main function of a DC reactor for inverter is to smooth current and suppress harmonics, not to reduce voltage.
