MEASTEK HCTM1200A High Sensitivity High Current Test Probe 0.9Hz
Excellent Low Frequency Performance Dedicated For IGBT Current
Measurement
High sensitivity for large currents
The high sensitivity of 5mV/A enables it to maintain high accuracy
when measuring large currents. It can accurately measure the peak
current of 1.2KA, which is an indispensable tool for monitoring and
maintaining large current equipment such as large mechanical
equipment and industrial production lines.
Fast response current probe
dI/dt reaches 10KA/μs, and has the ability to quickly respond to
current mutations. In some occasions where the current changes
rapidly, such as the switching moment of power electronic equipment
and the starting process of the motor, it can capture the current
change in a timely and accurate manner and provide you with a
complete current change curve.
Stable and low-noise measurement environment
The maximum noise is 10mV Vpp, creating a stable and
low-interference measurement environment for you. Even in
industrial environments with strong electromagnetic interference,
the accuracy of the measurement data can be guaranteed.
Outstanding low-frequency measurement capability
The low-frequency bandwidth -3dB is 0.9Hz, which performs well in
low-frequency current measurement. For some low-frequency operating
equipment, such as large wind turbines, low-frequency transformers,
etc., it can accurately measure their currents, providing strong
support for the stable operation and maintenance of the equipment.
Sturdy shell, durable and resistant
The sturdy shell design has good impact and vibration resistance,
can adapt to harsh working conditions, and extend the service life
of the equipment.
