The WaveSculptor motor controller has 10,000µF of low-impedance capacitance across the DC bus input connections. An external precharge circuit is mandatory. When not driving a motor, the WaveSculptor does not draw any power from the DC bus. Therefore, to avoid any high voltages on the bus connector when it is unplugged, an external discharge circuit is recommended.
This product provides a method to implement these two requirements. It can be configured in multiple ways, depending on the safety / cost tradeoff you wish to make with your vehicle. Please refer to any relevant regulations when deciding what type of circuit to use.

The precharge controller is priced at A$250 (approximately US$200, €150) ex GST.
