RD9914B insulation withstand voltage tester is a safe and high-performance tester designed with high-speed MCUs and large-scale digital circuits.. The voltage rise and fall as well as the voltage frequency of the instrument are controlled by the MCU. It displays the breakdown current and voltage values in real time. And it’s also with the software calibration. Equipped with PLC, RS232C, USB interfaces, it is convenient to form a comprehensive test system with computer or PLC system. It can intuitively, accurately and quickly test the electrical safety performance indicators such as breakdown voltage, leakage current, insulation resistance and other electrical safety indicators of various measured objects.
