What is the input impedance on the voltage inputs of ION86x0?
Product Line
ION8650
ION8600
Environment
Voltage Measurement input impedance specification
Resolution
The AUX power order options of the ION86x0 have no design capacitance on the voltage measurement terminals. On these meters, the measurement terminals have 5 Meg-Ohms to Earth on all four terminals (V1, V2, V3, Vref).
The blade-powered order options do have a capacitive network for EMC filtering. The precise characteristics will depend on which terminals are used for the installation. See attached a simplified schematic diagram.
