Products introduction
KD50A series digital insulation resistance tester, also known as megohmmeter and high-voltage insulation resistance meter, is used for insulation resistance test. This instrument has the functions of large-screen LCD gray backlight display, data storage, data query, alarm, automatic discharge, charging, automatic shutdown, etc. At the same time, it also has the function of measuring DC voltage AC voltage absorption ratio and polarization index. The whole machine is beautiful, with wide range, high resolution, convenient operation, convenient carrying, accurate, reliable, stable performance, large output power and strong anti-interference ability.
KD50A series digital insulation resistance tester also has shock-proof, dust-proof and moisture-proof structure and can adapt to harsh working environment. It is a commonly used instrument for telecommunication, electric power, meteorology, computer room, oil field, electromechanical installation and maintenance, and industrial enterprise departments that use electric power as industrial power or energy. It is suitable for measuring the insulation resistance of various insulation materials and transformers, motors, cables and electrical equipment.
KD50A series digital insulation resistance tester consists of medium and large scale integrated circuits. This meter has large output power and multiple output voltage levels (6 voltage levels). The rated insulation test voltage range is 100V~15kV (the output voltage is determined according to the model), and the step adjustment voltage function can output a variety of different voltage levels (for example, the 15kV model can produce 12KV and other voltage levels, with a wider range of use), and the insulation resistance measurement range is 0.01M Ω~50T Ω (the measurement range is determined according to the model); DC voltage measurement range 0~1000V; AC voltage measurement range 0~750V; DC current measurement range: 0.01nA-6mA; Capacitance measurement range: 10nF~50uF.
