Industrial safety high current probe

CAT II 600V industrial safety protection! TR3130U(6MHz bandwidth/300A RMS) through the EN61010 certification, suitable for inverter, motor drive field. BNC interface is compatible with all brands, Fluke, McKexin, OWON and other oscilloscopes are plugged and used directly, and the measurement efficiency and safety of high-risk scenes are improved.

Pincer opening

Φ19mm fast ringing jaw × state visualization! Real-time feedback of jaw state, red light is always on when not biting, and 750A peak current measurement is anti-negligence.

Auto zero

One-key zeroing eliminates the zero offset caused by common mode noise and ensures the safety of frequency converter measurement.

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.
