The UNI-T UTP4150 is a professional high-frequency DC/AC active current probe featuring a wide 12MHz bandwidth and exceptional measurement accuracy. Part of the comprehensive UT-P4000 series, this probe excels at capturing both static and dynamic current components with high precision and minimal circuit disturbance. With its impressive 29ns rise time and dual measurement ranges, the UT-P4150 delivers the performance needed by engineers and technicians working with modern power electronics, motor drives, renewable energy systems, and other demanding applications.
Designed for seamless integration with oscilloscopes, this probe transforms the standard high-impedance BNC input oscilloscope into a powerful current measurement system. The UT-P4150 combines precision, durability, and user-friendly operation to help professionals accurately analyze current waveforms across a broad spectrum of applications where understanding both steady-state and transient current behavior is essential to successful design and troubleshooting.
The UT-P4150 employs sophisticated Hall Effect technology to provide true DC-to-AC current measurement capabilities. Unlike conventional current transformers that can only measure AC signals, this probe accurately captures the complete current waveform including DC offsets, low-frequency components, and high-frequency transients up to 12MHz. The implementation of advanced signal conditioning ensures minimal insertion loss, preserving circuit integrity while providing highly accurate measurements. With the ability to handle currents from 100mA up to 150A, the UT-P4150 offers the versatility needed for a wide range of applications from sensitive electronic circuits to high-power industrial systems.
