Features

― Measures voltage of each battery terminal with refernce to chassis

― Reports battery voltage

― Reports accurate estimates of the isolation status while the battery is having large voltage variations

― When the battery is not connected or if the battery voltage drops below 15 V, the parallel combination of the two

reported isolation resistances (for the high and low sides) is still accurate, as well as the sum total of the reported

high and low capacitances

― Measures and reports modeled leakage resistances per model adapted by the safety standards ISO6469-1, FMVSS

§571.305 and others

― Reports calculated isolation resistance in Ω/V per requirements of the safety standards

― Measures and reports the value of capacitance from each battery terminal to chassis

― Calculates and reports the energy stored by the total capacitance between the battery and chassis

― Reports uncertainty for all measured and calculated values

― Continuously monitors connections of the voltage sense lines to the battery terminals; reports inadequate

connections

― Continuously monitors connection of the unit to chassis; reports inadequate connection

― Provides high immunity to common-mode noise that can be present on the battery terminals

― Provides nonvolatile storage for the value of the maximum (design) voltage of the battery (used in calculations of

the isolation resistance and stored energy). If the actual observed battery voltage is higher than the set maximum

voltage, the higher value is used in the calculations of the isolation resistance and stored energy

― Provides nonvolatile storage for calibration of the voltage measurements and other parameters; all reported

measurements have their respective calibration parameters applied automatically

― Provides built-in galvanically isolated and intrinsically leakage-safe excitation source

― A single CAN message provides sufficient information for determination of the safety status of the system

― Initializes in under 6 seconds

― Fast detection of a rapid change in insulation resistance: The SIM100 detects an insulation value change in less

than 5 secs

― Warning and Fault alerts provided in the STATUS byte for low insulation resistance values
