SIGLENT’s high-voltage differential probe has good common-mode noise suppression ability, high input impedance and low capacitance, and can accurately measure differential voltage signals. At the same time, it has a large impedance to the ground, which can measure the floating signal. In addition, it is equipped with one-button zero adjustment and overload acousto-optic alarm function to ensure the safety and convenience of operation. It can be widely used in the research and development, debugging or maintenance of switching power supply, frequency converter, electronic ballast, frequency conversion household appliances and other electrical power devices.
