MEASTEK HCTM0300A High-frequency Flexible Current Probes Are The Best Choice For Distributed Current Monitoring With Bandwidth Advantages
HCTM0300A high-frequency flexible current probe is ideal for distributed current monitoring and power bus monitoring.
It can measure 0.3KA peak current and can effectively cope with high current test scenarios. The insertion loss is almost zero, only a few picohenries, which has minimal interference to the object being measured, ensuring that the measured data is true and reliable.
The length of the probe ring and the connecting line can be customized to meet the testing needs of different special occasions. Its low-frequency bandwidth -3dB is 4.8Hz, and its high-frequency bandwidth -3dB is 15MHz. It can accurately capture the detailed changes of the current signal, and has excellent performance in harmonic measurement, power monitoring and other fields, providing strong guarantee for the stable operation of the power system.
Application scenarios:
The power system current probe is used in automated production lines to measure the working current of equipment motors; in power distribution cabinet maintenance, it monitors branch currents; and in UPS power supply testing, it detects charging and discharging currents.
