Flagship high current probe

750A Peak Conquer Extreme Surge. TR3150A face the new energy inverter test with 500A RMS/5MHz bandwidth. BNC interface is fully adapted to laboratory equipment such as Keysight, Sigilent, Puyuan Jingdian, etc. Domestic imported oscilloscopes are connected and measured immediately!

Pincer opening

The Φ19mm large jaw can easily cope with 500A transient surge, the built-in sensor intelligently detects the jaw state, the red light warning when unlocked, and the new energy copper bar measurement has zero fault tolerance.

Auto zero

Rapid reset after 500A surge! Large current impact is easy to cause zero drift, thermal recovery mode 3 seconds to complete self-calibration, new energy test without cooling waiting.

Dual range design

Double range a key switch, small current to high power full control! The TR3130U adapts to multiple scenes in 0.1V/A(50A) and 0.01V/A(300A) double gears, and accurately captures the current waveforms of frequency converters, UPS and other equipment with a 6MHz bandwidth. Peak 500A resistance to transient impact, overload red label warning (OVER RANGE) active protection. 20mA resolution takes into account the detection of small standby current, and one-key switching avoids the trouble of frequent replacement of traditional probes.

Fast capture of transient signals

Whether it is the instantaneous voltage drop of the switching power supply or the sudden distortion of the high-frequency signal, the system relies on the high-speed signal processing architecture and intelligent trigger mechanism to lock and record the transient details in real time. The millisecond response matches the rhythm of signal changes, and weak jump characteristics can still be clearly extracted in strong noise environment, ensuring zero omission of key data in scenarios such as power integrity verification and RF fault diagnosis. Provide engineers with true and reliable transient behavior analysis to help efficiently locate hidden dangers in the system.
