Hemei Electronics is a domestic manufacturer specializing in the research, design and production of power supply current transformers, split core current transformers, clamp-type current transformers, high-precision current transformers and miniature voltage transformers. Measures AC current from 1A to 5000A with outputs of 0.333V, mA, 1A and 5A.
Split-core current transformers are designed for quick and easy installation.The CT's have an internal precision load resistor on the secondary winding that provides a safe, low voltage output and allows the secondary winding to be safely opened.
The split core current transformer are designed for fast and easy installation.The CTs are ideal for installation on existing electrical cables by clamping on the conductor.This method permits a safer,easy 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.

Our current sensors are split-core current transformers characterized by high accuracy and low phase shift.
They are precisely designed for the electronic measurement of AC waveform current, ensuring galvanic separation between the primary circuit (power) and the secondary circuit (measurement). Covering a range from 0 A to 125 A, these current transformers are primarily intended for mounting on the primary circuit.

Utilizing the principle of electromagnetic induction, the magnetic field generated by the wire current induces electrical energy through the magnetic ring coil, the magnetic ring coil adopts the open and close structure, which is directly stuck on the cable conductor, and the output of the coil outputs a regulated DC power supply through AC/DC conversion.
