Precharge Contactor — symbol and terminals
The Precharge Contactor is an educational high-voltage model used in the EV High Voltage section of the lab. Contactor that charges link capacitors through a resistor. Place the symbol on the schematic, wire the listed terminals and run the solver to explore its behaviour. Models are simplified for teaching and must not be used to design or service real equipment.
| Terminal | Name | Function |
|---|---|---|
| in | Input | left |
| out | Output | right |
| coil+ | Coil + | top |
| coil- | Coil - | bottom |
