DC Smoothing Reactor
Installed on the DC side of converters, the DC smoothing reactor limits the AC ripple superimposed on the DC current. It also decouples parallel VFDs, limits circulating current and fault current rise rate, and smooths the DC link of current- and voltage-source inverters and rectifier power supplies.
Key Features
Precision Core Construction
Imported cold-rolled silicon steel core with two-limb structure and square yoke, pressed by tie rods to minimize noise.
Dry-Type Self-Cooling
Dry-type natural cooling design, available in Class B and Class F insulation.
Compact & Quiet
Small size, low temperature rise, and low noise.
Wide Current Range
Rated current from 2A to 10kA to match different converter and DC-side demands.

Why Choose WeiLian
01 Wide Current Range
Source DC smoothing reactors from 2A to 10kA, giving your engineers room to match different converters and DC-side operating demands.
02 Built Around Converter Requirements
Current, inductance, insulation class, dimensions, and mounting can be adjusted around your converter rather than forcing redesign around standard hardware.
03 Small Batches Welcome
MOQ starts from one unit, making replacement projects, converter upgrades, and early-stage equipment development easier to validate before volume purchasing.
04 Every Unit Electrically Verified
100% electrical testing checks key reactor performance before dispatch, giving procurement and engineering teams clearer acceptance evidence for delivered units.
