Micro Precision Current Transformer

Micro Precision Current Transformer operate on the principle of electromagnetic induction, where an alternating current in the primary conductor induces a proportional current in the secondary winding via a high-permeability micro-core. Unlike conventional CTs, MCTs utilize advanced materials (e.g., nanocrystalline alloys) and compact structural designs to achieve precise signal scaling while maintaining minimal phase error.

Product Features

    1. Miniaturized Design: With volumes as small as 1 cm³ and weights under 5 grams, MCTs integrate seamlessly into space-constrained applications like PCB-mounted sensors and portable devices.

    2. High Accuracy: Achieves 0.2%–0.5% ratio error and ≤10′ phase displacement, even for currents as low as milliamperes, ensuring reliability in precision measurement.

    3. Broad Frequency Response: Supports bandwidths from 50 Hz to 100 kHz, enabling accurate monitoring of harmonics and transient currents in modern power electronics.

Common Applications

    1. Smart Meters: Enable energy measurement in compact residential and industrial electricity meters.

    2. Medical Equipment: Monitor leakage currents in patient-connected devices (e.g., MRI machines, infusion pumps).

    3. EV Charging Systems: Provide isolated current sensing in onboard chargers and battery management.

    4. IoT Sensors: Power low-energy wireless nodes for predictive maintenance in industrial automation.
