Magnelab is one of the world’s most respected companies who design and manufacture AC current sensors and current transformers. We are also the original manufacturer of the split-core current transducer. All our transformers and transducers measure different AC current ratings, from microamperes to as much as 20,000 Amps. Our Rogowski Coil flexible-core RopeCT comes in lengths of between 12 and 48 inches and also have various amperage ratings. Furthermore, we design a range of high quality custom magnetics devices. We work together with individuals and industries such as energy monitoring, aerospace, computer and medical alike.

Producing quality magnetics for more than 46 years
