Jiangyin Spark Electronic Technology Co., Ltd. is a professional manufacturer specializing in current transformers and current sensing solutions. Founded in 1995, we have nearly 30 years of experience in the development and manufacturing of current transformers, Rogowski coils and related current sensors.
Our products are widely used in energy monitoring, power meters, solar inverters, EV charging systems, industrial equipment, smart buildings and electrical power monitoring applications.
Jiangyin Spark Electronic manufactures a wide range of current sensing products for different current measurement applications, including:
Split Core Current Transformers
Flexible Rogowski Coils
Rogowski Coils with 5A Output
UL2808 XOBA Split Core Current Transformers
Solid Core Current Transformers
Outdoor Waterproof Current Transformers
Busbar Current Transformers
Hall Effect Current Sensors
Miniature Current Transformers
Miniature Voltage Transformers
Different current ratios and output signals are available according to the application, including 333mV, 100mV, 1A, 5A, 4-20mA and other customized outputs.
Flexible Rogowski coils are one of our key product ranges for high-current measurement.
Compared with conventional large current transformers, Rogowski coils are flexible and easy to install around existing cables and busbars, making them suitable for retrofit installations and applications with limited installation space.
We provide Rogowski coil solutions for different measurement requirements, including voltage output, current output and customized signal output.
For power meters designed for standard 5A CT inputs, we can also provide Rogowski coil systems with 5A AC output, with primary current ranges such as 1000A/5A, 2000A/5A and 3000A/5A.
Our split core current transformers are designed for convenient installation without disconnecting existing cables.
They are widely used in energy monitoring systems, power meters, solar inverter systems, EV charging equipment, building energy management and industrial power monitoring.
Different window sizes, primary current ratings and secondary outputs can be selected according to the installation and measurement requirements.
We also manufacture UL certified current transformer models for applications requiring certified current sensing components.
With our own production and assembly facilities, Jiangyin Spark Electronic manages key manufacturing processes and product inspection in-house.
Quality control is carried out throughout production, from raw material inspection and assembly to electrical testing and final inspection.
Our manufacturing experience allows us to support both standard products and customized current sensing solutions for OEM customers.
Jiangyin Spark Electronic has developed current transformer products with certifications including UL, UL2808 and CE for different product series.
Customization is available according to customer requirements, including:
