Tronovo angstrom current probes are designed with an open design that allows the current probe to be easily connected and disconnected from the conductor, allowing for accurate measurement of DC and AC signals by simply clamping the wire. We offer a wide range of models to choose from, with a maximum bandwidth of 100MHz and the ability to measure currents from 50mA to 40A.
Features:
• Bandwidth: DC~50MHz
• Measurable current range: 50mA to 40A
• AC/DC measurement of AC or DC waveforms
• Clamp opening eliminates the need to disconnect the circuit under test
• Current conversion ratio: 50mV/A
• Narrow jaw design, easy to use in dense and tight spaces
• Zero Adjustment: Aligns the baseline position of the probe
• Degaussing function: eliminates DC measurement interference
• External power supply, 5V power adapter
• Universal interface, compatible with BNC interface oscilloscopes

High frequency high current probeThe TR3040B extends the bandwidth to 50MHz (rise time ≤ 7ns), taking into account high-frequency response and high-current capability, perfect for dynamic testing of switching power supplies and on-board electronics. The 40A DC/28A AC RMS range (Figure 13) with a 50mV/A conversion ratio provides high signal-to-noise ratio data in power tool and industrial controller scenarios. Fully compatible with the mainstream oscilloscope, BNC output directly connected after the probe menu configuration parameters. |
Pincer openingThe long and narrow jaw structure takes into account high-frequency response and high current: the 4.5mm opening supports one-key opening and closing, seamlessly clamps the wires of electric tools or industrial controllers, and the whole process is continuously powered. The 50MHz bandwidth and low noise design ensure dynamic current signal integrity, and the 4.5mm size adapts to standard cables, providing a safe and efficient online monitoring solution for high-speed production lines. |

Zeroing and degaussingZERO knob accurately calibrates the small offset at 40A DC; DEGAUSS key actively disintegrates the high-frequency magnetic residue of the switching power supply,. Aiming at the dynamic load characteristics of power tools, the design realizes "one key to zero" in the 10kHz ~ 50MHz broadband domain, avoids the cumulative error caused by pulse current, and provides a maintenance-free and efficient calibration scheme for mass production testing. |
Low noise≤ 1mVrms ultra-low noise base, achieving industry-leading signal-to-noise ratio at 0.05V/A attenuation ratio. Its 50MHz bandwidth (rise time ≤ 7ns) effectively suppresses high-frequency interference by optimizing input impedance characteristics, and the measured PWM waveform noise fluctuation of switching power supply is<0.8mV, ensuring accurate capture of small ripple in 28A AC high current scene. |
