DCL Balance Reactor

The DCL Balance Reactor is engineered to enhance DC link stability and protect power electronic devices by suppressing current mutation, limiting surge/inrush current, and reducing high order harmonics. Built with high quality copper wire and a silicon steel (iron) core, it offers safe, stable performance with low temperature rise and low noise, helping improve system reliability in demanding applications. Typical configurations support Rated Voltage options such as 380V/690V (customizable), with a wide operating current range of 5A–1600A and 50Hz/60Hz frequency. Inductance is customizable to match your DC link and converter design. Optional insulation is available in Class F / Class H, and the reactor supports short time overload up to 1.5× rated current for 60 seconds (configuration dependent). Common application fields include new energy, rail traffic, EV charging piles, and industrial power supplies & UPS. (Specifications can be customized—please confirm final data when ordering.)

Key Features

• Suppress Current Mutation: Limits rapid DC current changes to protect IGBTs, diodes and other power devices from instantaneous overcurrent damage.
• Safety Protection: Reduces surge/inrush current during startup and load steps to improve system robustness.
• Energy Storage & Freewheeling Support: Stores energy during commutation and helps provide a continuous current path for the load.
• Suppress Harmonics: Lowers interference from high order harmonics generated by converters, improving power quality.
• Industrial Grade Materials: Copper windings and silicon steel core deliver stable inductance, durability, and reliable thermal behavior.
• Customizable Electrical Specs: 380/690V (customizable), 5A–1600A, 50/60Hz, optional Class F/H insulation, and customizable inductance.
