The SCTK681B series of split core current transformer are designed for fast and easy installation.The split core design permits non-contact current measurements through magnetic field induction without requiring that the primary wire be taken offline and disconnected for CT installation.This method permits a safer,easier and portable current measurement. An internal precision burden resistor across the secondary winding of the CT provides a safe low voltage output and permits safe opening of the secondary

FAQ
Q: How to choose between 0.333V and 0-500mA outputs?
A: 0.333V output is a low-voltage signal, suitable for electronic energy meters, PLCs, and voltage-input measurement instruments. 0-500mA output is a current signal, suitable for control systems and traditional measurement equipment that require current signals. Please choose based on your measurement equipment input interface.
Q: What is the function of the built-in precision resistor?
A: The secondary winding has a built-in precision parallel resistor. It converts the current signal directly into a safe low-voltage output (0.333V) or standard current signal (0-500mA), eliminating the need for external sampling resistors. It also allows safe open-circuit operation on the secondary side, improving operational safety.
Q: What about the accuracy and core loss of this product?
A: This product uses a high-precision openable core design with low core loss, ensuring high-accuracy current measurement across the entire measuring range, meeting various industrial and power monitoring application requirements.
Q: How to apply for samples? What is the lead time?
A: You can submit a sample application through our website or email. Please provide your company information and target model. Samples are free of charge and will be shipped within 3-5 working days. Mass order lead time is generally 2-8 weeks.
