TK4300 Multi channel Electrical Parameter Measurement Analyzer TK4300 is an instrument used for comprehensive analysis of various electrical parameters in electrical circuits. It is suitable for measuring and analyzing AC and DC parameters on the input and output sides of electric vehicle charging stations (machines). It can measure dual voltage of DC~100 kHz and analyze power/energy with an accuracy of 0.05 level. This instrument, together with other equipment, can be used to build a comprehensive testing platform for electric vehicle charging piles (machines). It is suitable for the metrology and testing industry, power industry, manufacturing units, research institutes, universities, etc. to conduct full performance testing (type evaluation, etc.), factory inspection, and arrival acceptance of charging piles (machines).
