High load high current probe750A peak 500A RMS ultimate load! TR3150U(5MHz bandwidth) is optimized for new energy battery/high-power power supply testing. BNC interface plug and play support Keysight, Rigol, Dingyang and other high-voltage oscilloscopes, domestic imported equipment seamless connection, heavy-load current test efficiency doubled. |
Pincer openingThe clamp-on opening structure can easily handle thick wires or busbars with a maximum diameter of 13mm. The one-key opening and closing handle design can quickly and firmly clamp the tested conductor even if wearing gloves, without disconnecting the power supply in the whole process, ensuring the continuity of the test. |

Auto zeroBuilt-in one-key calibration function, 3 seconds to complete accurate zero, completely bid farewell to complex manual process. No need for professional background, novice is ready to use; Senior engineers can save 50% of operation time and focus on core tasks. Efficient and labor-saving, so that each device always maintain the best measurement state, productivity soared! |
Dual range designDouble gear covers full current, one-key switching and efficient measurement! The TR3150U is designed with 0.1V/A(75A) and 0.01V/A(500A) dual range, and the 5MHz bandwidth stably supports high-voltage systems such as motor drives and photovoltaic inverters. Peak value 750A is impact resistant, 1% accuracy combined with 200mA resolution, and can be accurately captured from standby power consumption to full load current. One-key degaussing and zeroing (AUTO ZERO green light prompt) eliminates environmental magnetic field interference, and flexible switching of double gears greatly improves test efficiency. Economical high-load solutions, so that high-current debugging security worry-free! |

High-frequency signal testThe high-frequency AC/DC current probe is comfortable in measuring 5MHz signals, and the waveform is clear and faithful (CH1 yellow waveform); However, the same frequency test of the low-frequency probe is seriously distorted (CH2 pink waveform), resulting in signal distortion due to insufficient bandwidth! The high-frequency probe accurately captures high-frequency details such as transients of switching power supply and harmonics of new energy current with a bandwidth of 20MHz + (e.g. TCP0150 up to 20MHz and CP503B up to 50MHz) and an accuracy of ≤ 1%. Its low insertion loss and anti-saturation design (such as Hall closed-loop technology) ensure 0 distortion of amplitude and phase of 5MHz signals, and its dynamic range reaches 110dB. |
