This shunt regulator can protect power supplies from voltage spikes generated by motor controllers they are connected to. This version has a fixed set point of 33.0 V, a shunt resistance of 32.8 ohms, and four SMT shunt resistors populated on one side of the PCB. This version is intended for those who want to use this board with a higher-power external shunt resistor. An external potentiometer can also be added to change the set voltage.
