❓ Common Industry Inquiries

Why choose Rogowski coils over traditional CTs for smart storage? +
Rogowski coils offer high accuracy (AN1V PB512 class), no saturation, and flexibility, making them ideal for measuring high currents in tight spaces within Battery Energy Storage Systems (BESS) where traditional iron-core transformers might fail due to space constraints or magnetic saturation.
How does Fujian Smrtr ensure long-term reliability for outdoor installations? +
Our outdoor products, such as the Jlszv-35W Metering Box and waterproof split-core CTs, use epoxy resin casting and specialized anti-corrosion materials to withstand extreme temperatures and humidity, ensuring a service life exceeding 15 years.
Can you provide OEM/ODM services for specialized industrial designs? +
Yes. With a team of 20 senior engineers led by industry-renowned professors, Zentar® specializes in custom magnetic component design, ranging from 21mm slim split-core transformers to multi-thousand ampere sensors for industrial welding.
What is your production capacity for wholesale orders? +
We have an annual capacity of 50 million magnetic components and 5 million electrical safety products. Our ERP-managed facility ensures short lead times even for large-scale global wholesale requirements.
