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.
