Emulation of NTC/PTC temperature sensors for the high voltage area up to 1kV

The NTC/PTC-Simulator is a galvanically isolated resistor cascade, that is controlled via CAN bus in the range of 0..8MOhm. The resistor cascade can be used in the high voltage area up to 1kV and is especially designed for the simulation of temperature sensors for electric vehicle batteries. It can be used wherever an adjustable resistor is needed.
