Custom High Current Reactors: Vertical Power Solutions for Inverters

Sub-headline:

Engineered for high-density power conversion. As a leading Custom Inductor Manufacturer, we deliver High Current Reactors featuring Flat Copper Wire technology and a vertical block structure to maximize space efficiency while handling currents exceeding 50A.

Key Highlights:

Vertical Space Saving: The optimized vertical orientation (65mm height) allows for a smaller footprint on the PCB, critical for compact PV Inverter designs.

Flat Wire Efficiency: Utilizes heavy-gauge Rectangular Wire (2.2x1.4mm) to maximize the copper fill factor and significantly reduce skin effect losses at high frequencies.

High Saturation Stability: Built with high-performance magnetic cores to maintain inductance (265µH) even under peak current loads.

Reference Case Study: Model SIP6KL266W50H65

Note: The specifications below are from our production model SIP6KL. This demonstrates our manufacturing capability for Vertical High Power Reactors.

Parameter	Specification (Reference Only)	Customization Range
Model P/N	SIP6KL266W50H65	Custom P/N assignment available
Category	High Power Reactor	Output Filter / Boost Inductor
Dimensions	52.5 x 50.0 x 65.0 mm (Max)	Scalable (e.g., SIP3KL - SIP10KL)
Inductance (L)	265 µH ± 10% (@1kHz)	50µH - 5.0mH (Optimized for Current)
Rated Current	50 A (Irms)	20A - 200A+ (Flat Wire Design)
DCR (Resistance)	18 mΩ Max	Ultra-low DCR options
Wire Specs	2.2 x 1.4 mm Flat Wire	Copper / Aluminum Flat Wire

Engineer's Insight: The SIP6KL is a workhorse for the 50A class. By employing Edgewise/Flat winding with a 2.2x1.4mm conductor, we achieve an exceptionally low DCR of 18mΩ in a compact vertical form factor. This makes it an ideal choice for the output filter stage of solar inverters.

Tailor This Reactor to Your Needs

We engineer High Current Reactors to fit your thermal and electrical constraints.

Flat Wire Technology Advantage

Why Flat Wire? In High Current Reactors, standard round wires leave significant air gaps. Our Flat Wire Inductor technology stacks conductors perfectly, improving thermal conductivity and allowing the component to run cooler.

● Cost Optimization: For cost-sensitive projects, we can replace the copper flat wire with Flat Aluminum Wire, offering up to 20% cost savings while maintaining the same physical footprint.

Core & Structural Customization

● Material Selection: We utilize Sendust, High Flux, or Silicon Steel cores depending on your operating frequency (50Hz vs 20kHz).

● Mounting Options: The SIP series can be customized with Heavy-duty Terminals or Busbar connections to facilitate easy integration into high-power cabinets.
