Customization Process Guide

From Concept to Mass Production

Professional engineering team & automated production lines ensuring every CT and Rogowski coil matches your specs precisely.

Requirement Analysis & Solution Design

We go beyond order-taking by analyzing your application (PV, storage, EV charging) to define key parameters—turns ratio, accuracy, linearity, and dimensions—while optimizing integrator matching and anti-interference design for Rogowski coils.

Rapid Product Prototyping

Once the plan is confirmed, we initiate rapid prototyping. Utilizing our modular core inventory and flexible winding processes, we produce functional samples within 15-20 days, allowing you to proceed with circuit testing and validation ASAP.

Rigorous Testing & Validation

Samples undergo strict functional and environmental testing, including ratio and phase error calibration, as well as withstand voltage, temperature rise, and EMC tests to meet IEC 61869 and application requirements.

Scalable Mass Production

After approval, we move to mass production using automated winding and epoxy casting lines, ensuring consistent magnetic performance and insulation reliability, with monthly capacity over 500,000 units.

Final QC & Global Delivery

We perform AQL sampling or 100% inspection before shipment to ensure zero defects in appearance and performance. Familiar with export packaging standards, we provide shock-proof and moisture-proof packing for on-time global delivery.
