Product Detail
A PCB current transformer is a miniaturized, high-precision current sensor specifically designed for printed circuit boards. Its features include small size, easy installation (direct soldering to the board), good packaging, high accuracy, wide output linear range, and small phase shift.
It is widely used in electronic energy meters, EV charging piles, motor protection, power monitoring, energy management, and other scenarios requiring precise measurement and monitoring of circuit current, enabling the proportional conversion of large currents into smaller currents for use by instruments and protection devices.
Product Feature
Integration and Small Size: Compact design, directly solderable to PCBA, saving space and additional connecting wires.
High Precision: High accuracy and small phase shift, meeting the requirements of power metering and energy measurement (e.g., Class 0.1, 0.2).
Wide Linear Range: Maintains high linearity over a wide current range.
Excellent Insulation: Typically encapsulated in epoxy resin, offering high power frequency withstand voltage and strong insulation.
High Adaptability: Stable output signal, well-matched to power systems (e.g., three-phase).
Versatility: Available in various window sizes and package types; customization is available.
