FAQ
Q: Does the split-core current transformer require power-off or cable removal during installation?

A: No. The SCTK671 series uses a split-core structure with a core that opens and closes. It can be installed without disconnecting or removing any cables or busbars. It is especially suitable for retrofit projects and applications where power cannot be turned off, significantly reducing installation costs and time.

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 (0-10V), eliminating the need for external sampling resistors. This simplifies installation, improves safety, and saves component costs and installation space.

Q: What are the advantages of epoxy potting?

A: Epoxy resin potting provides excellent insulation, moisture-proof, dust-proof, and corrosion protection, while also enhancing the product's vibration resistance. The completely enclosed structure ensures long-term stable operation of the transformer in various harsh environments.

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.
