製品説明
DC-004 20-60A Single Phase DC Bus Reactor Choke for VFD Inverter
The DC-004 Single Phase DC Bus Reactor Choke is a high-reliability electrical component specifically engineered for VFD (Variable Frequency Drive) inverters, featuring an adjustable rated current range of 20-60A. As a core part of the VFD DC bus circuit, it is designed to optimize power quality, protect inverter components, and ensure stable operation of the entire drive system, widely applicable in industrial automation and motor drive scenarios.
Construction & Design
  • Dry-type iron core structure using high-quality low-loss cold-rolled silicon steel sheets
  • Core column divided into uniform segments with air gaps separated by epoxy laminated glass cloth plates
  • Special adhesives prevent air gap displacement and avoid magnetic saturation during operation
  • Coil tightly wound with F-class high-temperature enameled copper wire
  • Excellent insulation performance and good heat dissipation
  • Temperature rise limit of ≤95K, suitable for long-term continuous operation
Key Functions & Benefits
  • Effectively suppresses high-order harmonics and current ripples in the DC bus
  • Smooths voltage fluctuations and limits inrush current and short-circuit current
  • Protects IGBT modules and other core components from damage
  • Improves power factor and reduces electromagnetic interference (EMI)
  • Relieves DC bus voltage stress
  • Extends service life of both VFD inverters and connected motors
Technical Specifications
Standard Compliance IEC289:1987, GB10229-88, JB9644-1999
Protection Grade IP00
Operating Noise ≤65dB at 1m distance
Overload Capacity 1.35 times rated current for 1 minute
Rated Current 20-60A (adjustable)
Applications
Perfectly compatible with various single-phase VFD inverters, suitable for small and medium-power motor drive systems such as industrial pumps, fans, and conveyors. Provides reliable power filtering and protection for the entire system with compact size, lightweight design, and easy installation.
