The VClamp adapter allows RoboClaw or MCP to be used with switching power supplies. It dissipates the excess regenerative energy through a connected resistor. The regenerated power from a brushed DC motor can cause switching power supplies to shutdown due to over voltage. The VClamp can be controlled by RoboClaw or MCP and is activated when the set maximum voltage of the RoboClaw or MCP is exceeded. VClamp is also ideal in battery system where the regenerative voltages need to be controlled to prevent over charging.
