Product introduction

 

This series of program-controlled withstand voltage tester adopts high-performance safety tester designed by high-speed MCU and large-scale digital circuit. The output voltage, rise and fall of output voltage and frequency of output voltage are completely controlled by MCU. It can display breakdown current value and voltage value in real time, and has software calibration function. It is equipped with PLC interface, RS232C, RS485, USB device and USB Host interface can be used to form a comprehensive test system with computer or PLC. Rk99 series of program-controlled medical withstand voltage tester has all the functions of the conventional voltage withstand tester, and the arc (flashover) detection function is added. Through the external oscilloscope, the "flashover" phenomenon of the electrical equipment under test can be detected intuitively, accurately, quickly and reliably. When there is no "flashover" phenomenon in the tested electrical equipment, the oscilloscope displays a stable "Lissajous figure, that is, a closed circle In case of "flashover" of the tested electrical equipment, a larger "flashover" phenomenon of electrical equipment will appear in the edge green of Li Shayu's figure to ensure the safety of the tested electrical equipment. This product is also suitable for testing various electrical equipment with flashover defects. It is an indispensable withstand voltage tester for medical electrical equipment manufacturers, maintenance departments, users, product quality inspection departments and technical supervision departments.
